One thing I have always loved about CG artis that there is no "one right way" to do

things. For any given task, there are anumber of methods, techniques and tools to getit done.

And while Blender has a powerful selection oftools, sometimes the "fake" or "cheat" is oftenpreferred for various reasons. Time and hard-ware limitations are generally the biggest rea-sons for using a "fake" or "cheat".

And then sometimes the tool actually helps cre-

ate the "fake", as in the case of normal maps.Once set up, a normal helps you "fake" geome-try and details that would take too long torender or cause time delay and memory issuesfor game models.

Well enough chattering from me, after the longwait for this issue, I'm sure you want to dive inand get your Blenderart fix.

Have fun!

IntroductionOver the years I have used a number of fakes, cheatsand workarounds. Some I have used because therewasn't a tool or option coded yet and some becauseit was either easier to use the fake or because itsaved render time.

Of all the fakes I have used (or read about), my fa-vourite has always been the "Light gel", used to cre-ate interesting shadows. Almost since the beginning

of traditional photography and film making the Lightgel has been used for creating interesting effects.

So just what is a "Light gel"? In traditional photogra-phy and film making, the term applies to sheets ofacetate (or other similar clear materials) with pat-terns printed on them, such as bars, window panes,leaves etc. The light gel is then held in front of thespecified lamp or light source to create the shadowpatterns. (Light gels can also be colored to createmoods or colored shadows.)

In Blender, this technique is easy to apply and doingso can save not only on modeling and set up time,but it can save quite a bit on your final render time.

So just how do you go about setting thisup?

To create light gels in Blender, you simply add tex-tures to your lamps. It's really that simple. You canuse either procedural textures or images (grayscaleseems to work best.)

You set up Lamp textures the same way you do formaterials, (in the Texture buttons [F6]). Some fun tex-ture types to try are Wood and Clouds. Both add

great shadow patterns. You can experiment with theother texture types to create more unusual patterns.

To create somewhat more realistic shadow patterns,of say, tree branches and or leaves, you can use agrayscale photo. Then when applying the texture tothe Lamp, choose Image as the texture type and pick

your grayscale photo. Instant shadows.

IntroductionThere are generally regarded to betwo ways to generate normal mapsfrom 3D content; renderbump andrenderbumpflat. The following tu-torial discusses the creation of nor-mal maps in the context ofrenderbump, that is, using Blender3D's own internal ability to 'bake' the

topology and physical characteristics of a high reso-

lution, highly detailed 3D object to an image called a"normal map" (#).

An understanding of Blender's basics is required, sobeing able to move objects, change views and ma-nipulate objects will be necessary. It's also assumedthere are assets available and ready for use - the in-formation below won't discuss how to make highresolution 3D models.

Baking normal maps, what's needed?

To successfully bake normal maps using Blender 3Da number of items are required before anything canbe done;

A low poly 'game' mesh

A high poly 'art' mesh

The low poly 'game' mesh is the actual mesh thatwill eventually be used in game, in this instance a'tech' door shown on the left of the image belowmarked low poly, this should be 'optimised' aswell as possible (as few polygons as necessary for itstarget use), and must be UVW mapped and textured.

The high poly 'art' mesh will be used to providethe geometric detail that's baked to the image ap-plied over the game mesh. The "high poly" version ofthe door is shown on the right of the image below.

Design note : A third version of the model is often used,

called the "control cage", this is optional and more todo with work practices (#).

Preparing the models, what needs to bedone beforehand?

Because the high resolution object is effectively be-ing baked to the low resolution one, there needs tobe a way for the baking process to understand what

it's supposed to be doing in relation to both objects.In other words, Blender needs to know where it'ssupposed to 'bake' (or 'write', 'paint') the colourednormals, what areas of the texture image shouldhave baked normals and what areas shouldn't.

For this to happen the low poly mesh must have afunctional UVW map with materials and textures as-signed.

Taking the example of our tech door, shown below is itsUVW map as laid out and occupying a partial section ofthe available image space; it only uses a section be-cause other objects use the same rusty metal texturesheet; keep that in mind when UVW unwrapping, leavespace for other objects where necessary.

Design note : keep in mind that depending on how manyassets need to be UVW unwrapped and normal mapbaked, the distribution and amount of space available foruse by any given individual object will need to be adjustedwhere appropriate (#).

The high poly mesh does not need to be UVW mapped.

HOW TO : Create or edit a UVW mapBefore doing any UVW unwrapping it's best to makesure the low resolution model has at least one material

assigned to the mesh and at least one image/textureassigned to that material, this is important for the nor-mal map baking process.

Note : Render baking is only available with Blender ver-sions 2.45 or above.

For Blender 2.45 only;

In the 3D view, RMB select the object to be UVWunwrapped and then press [F] to enter UV FaceSelect mode.

Press [A] to select all the UV faces of the object(this may need to be done twice, once to de-selectalready selected faces, and again to then re-selecteverything).

Press [U] to activate the UV Calculation pop-upmenu and select Unwrap, this will create a basicUVW map of the object.

For Blender 2.46 or above, do the following;

Press [Tab] to enter edit mode as you would nor-mally when editing the mesh.

Press [A] to select all the objects faces (may need tobe done twice, as above).

Then as above, press [U] to activate the UV Calcu-lation pop-up menu and select Unwrap.

Unwrapping the mesh will create a basic UVWmap for the object which will generally occupy thewhole image or as much space as it's proportions

will allow.

8/41

Note : It is also beyond the scope of this tutorial to cover,in any great length or detail, the various aspects and fea-tures of UVW mapping available.

If the model shares the texture sheet applied to it withother objects, that usually means the new UVW mapwill need to be scaled back to a more reasonable size toallow or compensate for the presence of other subse-quent objects on the same texture.

So, for all versions of Blender 2.45 or above, do the fol-lowing;

Either divide the interface ([RMB] on a windowedge divider, select Split) so a separateUVW/Image Editor is available, or, switch to thatview [Shift+F10]; the newly created UVW mapshould appear superimposed over the top of theimage that's assigned to the material - press [Alt+Z]to toggle the display of the texture on the model tocheck.

In the UV/Image edit view, press [A] to select UVfaces (may need to be done twice as mentioned

above), and then [S] to initiate Scale, simply movethe mouse to scale the selected UVW map up ordown, [LMB] to set the move.

This should result in a UVW map similar to the imageabove, where the map itself occupies an appropriateamount of space on the image.

Preparing the models, where to put them

It's important to note at this point that baking normalmaps in this way is a "like for like" process, it's not ex-plicitly a 'projection' - one object being 'projected' ontoanother - but rather relies on the objects occupying theexact same co-ordinate in 'XYZ' space. In other words,

the objects have to sit on top of each other in order forthis process to work correctly.

Shown below are both the high and low poly meshesplaced at the exact same 'XYZ' co-ordinates on Blendersgrid. It's important, at this point, to make sure thatboth objects are placed exactly on top of each other -it's helpful here if both objects have the same POO('point of origin' - the little pink spot around which thecursor is usually placed when objects are selected).

HOW TO : precision position control

Assuming that both objects are using the same POO, inorder to move or position them with precision doeither/or of the following;

RMB click to select and object and hold [Ctrl]whilst moving, this will 'snap' the object to thegrid as it's moved.

And/or

Press [N] to open the Transform Properties panel,

in the LocX, LocY and LocZ text fields, enteror edit the numbers shown so that both objectsuse the same values; this ensures both objects arein the same place 'numerically'.

This should put both the high and low objects into thesame place; usually confirmed by the presence of some-thing called z-fighting - this is the 'flicker' often seenas a result of your graphics card trying to draw copla-nar surfaces at the same time (surfaces that occupy thesame surface at the same time), as it can't do that, itswitches or swaps the rendering of one surface withthe other as the object is moved and rendered to themonitor screen.

Once this initial preparation is done to both meshes,it's time to render the normal maps.

WARNING : Do not skip the above steps, make sure thelow poly mesh has a good 'clean' UVW map and thatboth objects are in the exact same place; taking shortcuts and ignoring the above will result in poor renderresults and wonky renders (for more on this see the

'advanced' section).

Baking normal maps with Blender

Baking normal maps with Blender is straight forward,both the high and low resolution versions of the modelneed to be selected, a few options active and a 'render'button pressed.

HOW TO : render bake normal maps

The order in which the two mesh objects are selected isimportant so make sure to do this correctly;

10/41

RMB select the high resolution mesh first, then hold

the Shift key down and RMB select the low resolutionmesh - of the two meshes the low resolutions outlineshould be the brighter pink when done in the correctorder.

Switch to the Scene panels window, [F10], and findthe panel titled Bake.

Click the Selected to Active as well as theNormal button.

Depending on where the normal map is going to be

used, the drop down selection menu - currently show-ing Tangent - may need to be changed to the appro-

priate setting; for game content this is usually

Tangent, select that setting if it's not already active.

Additionally activate the Clear button, this will forceBlender to clear the texture before it re-bakes the nor-mal map, handy if the process is run several times.Margin can also be set which will force a 'bleed'amount to avoid edge anti-aliasing errors (#).

Click the BAKE button to render bake the normalmap to texture.

If the UV/Image editing window is open, baking will be

visible as the progressive 'live' creation of the normalmap as it gets baked to the texture image - dependingon how big the image is, it shouldn't take too long toprocess. The result will be something similar to what'sshown below - the normal map baked to the areamapped out by UVWs of the low resolution mesh, allthat then needs to be done is to save the image. So;

HOW TO : save the baked normal map

On baking the normal map to image a small * should

appear appended to the Image menu text of the viewheader once the process is done (it will appear asImage* instead of the default Image); this indicatesthere is a new image being held in the render buffer,which now needs to be saved.

Click Image and select Save As..., a file browsewindow will open.

In the header area of the newly opened file browsewindow, find the drop down menu Save Image[image type], and select an image format that willsave the image either in a 'raw' state, or one thatuses 'loss-less' compression; suggestions are TargaRaw, BMP or Tiff.

Conclusion

Using Blenders own internal normal map render capa-bilities is a quick way to generate game ready normalmaps and providing the steps above are followed thereshouldn't be any major problems - most issues requiresimple 'tweaks' to fix. There are a couple of caveats tousing Blender for this process however, which are dis-cussed in the advanced section which can be foundhere.

IntroductionModeling an object efficiently is often aquestion of understanding its basic geo-metric shapes and imagining a wiremesh over that surface. How far is anobject a cube, a cylinder, where couldparts be extruded from, and in which or-der do you start working? Those ques-tions should be asked first before anyserious attempt is started because it can

save the time needed to model the sur-face and prevent time consuming re-tries.

The original Blend file is also accessible viaBlenderart.org and includes all the following mode-ling steps and objects.

The Big Bobby Car was in particular a good object todemonstrate that type of approach.

Lets look at the screenshots first and evaluate its

design and curvature qualities. There are possibledifferent approaches to start this model, however Ifound it to be easier to imagine this starting withthe curvy edge shape of the fender, extruding it in,scaling cross sections to meet the desired height forthe center parts, and then finishing it up by addingloop cuts and some pushing and pulling of controlpoints.

The Modifier hierarchy requirement:

In particular I make use of the modifiers such as themirror and subsurface because this isa symmetrical object and this way I only need tomodel half of it, but I can visualize it as a completeconstruction.

When using the modifier it is important to under-stand how the internal hierarchy works.

When you use the mirror modifier together with thesubsurf you want the mirror to be the first one. Thereason for that is the following one:

The first modifier passes the

geometric result to the follow-ing one.

This means when the mirror isthe first, the subsurf modifierwill get a solid geometry tosubdivide. Because it is a solidsurface the result will be niceand smooth without any kinksor breaking edges.

When the subsurf is the first,the mirror modifier will gethalf a model which is subdi-vided and willmirror exactly that, producinga shell which clearly shows aseam.

Modeling Steps of the main body:

Lets start with browsing some images online for theBig Bobby Car and find some inspirational and useful

images. In an ideal situation you want to have nice pro-file images. When they are hard to find, maybe handsketching some designs will help.

Also as a small tip for making your own profile images:when using a digital camera try to stay as far away aspossible from an object and zoom in as far as possiblebefore making the shot.

This will create a picture with a tunnel look, where per-spective distortions are minimized compared to stand-ing close to the object and using a rather wide anglewhich will distort your profile shots significantly. Thisalso applies to making reference shots of a human bodyor head.

In my scene I used a downloaded image from the inter-

net and worked in front and perspective view at thesame time - to make it easier for you to see what hap-pens in my scene and which steps I am executing.

Another tip before starting to work, besides saving of-ten, is to actually distribute different stages of yourmodels over the layers Blender has to offer. This way

you can first quickly go back to an older stage and sec-ond you can easily compare maybe 2, or 3 differentresults/stages by just browsing through the respectivelayers.

Putting down basic details:

Step 1As mentioned in the beginning I found the objectto be suitable to start modeling the curved shape of thefenders first. I started with a small cube, rotated andmoved the mesh to left side and started by extrudingthe form to the right. After each extrusion I rotated thecross section so that it was perpendicular to the curvesurface of the fender. I also used the upper edge as oneto orientate myself along. It is very important in thisstep to have perpendicular cross sections, because oth-erwise your fender thickness can change fast and alsothe flow will not be so even and easy to control.

Step 2 The

lower edgeof the ex-truded cubemodel is be-ing adjustedto moreclosely fol-low thelower line ofthe fender.Pay attention to how I moved points together to gently

sharpen edges and make other edges more linear.Step 3 Themodel wasscaled alongthe y axis tosomewhathalf of theBig BobbyCar's thick-ness and Iadded a loopcut where Iwould assume the engine part would flow into thefender surface.

Creating basic proportions for the engine area:

Step 4 I selected those points which by simply movingthem up could define the upper surface of the engineblock as well as the seat for the child's hip. It was veryimportant to arrange those points in side view insmooth curves. The space between the points should

be even and the continuity should be even and notshow any sudden changes which would read like dents.

Image Step-4-1 shows what I mean. A selection of

points is off and creating an undesired flow.

Also pay attention to how I again moved points closertogether to form sharper bends at the top left engineblock edge.

Step 5 With the same process also the lower part of thecar was modeled by simply pushing and pulling pointsand grouping them together to form sharper edges orby distributing them evenly apart to form even andnice bends.

To align points together I selected a row of points,pressed "s" to scale, selected the, in this case, z-axis bypressing "z", and entered "0" to move all points alongthe z-axis closer together along the x-axis.

15/41

Step 6 Through adding two loop-cuts at the displayed

position I sharpened the edge of the engine block nice-ly. The right loop-cutwas simply placed tothe right of the originalline. The left loop cutwas not placed initiallywhere it is right now. Iadded the loop-cutclose to the left edge ofthe model and thenmoved it along the y-

axis to form this sharpedge at engine block and having straight falling sidesurfaces sharply flowing into the surface of the fender.

Step 7 Now, to build the engine block itself I selectedspecific edge points and positioned them again along anice even curve trying to prevent kinks. To make theseat area more soft, Ialso moved their edgepoints away from eachother. Compare step 7with 7-1 and you will

see how much justsome push and pullingcan actually create al-

ready a quite impressive surface quality.

Finishing up the model with adding smallfeatures:

Step 8 At particularareas, I selectedsome faces and ex-truded them up-wards to form thebackrest and lampbodies. While I wasobserving my refer-ence images I wasplanning those inalready. You can see this by how fine I started with stepfirst, laying down already the required geometry forthat later coming task.

Step 9 As a finishingtouch, I selectedsome front centerpoints and moved

them straight downto give the car amore child-like,smiling attitude andexpression.

Step 10 This image shows a problem with my engineblock or hood edges. I highlighted the edge flow and

you can see that those rings form a specific edge flowwhich is nice along the sides but does not continue in-front of the hood along the smiling part of the fender.In this case I would need to re-arrange my edge flow

and with the given model it might be quite difficult toachieve.

However this is a minor problem.

Wheel Styling and efficient distribution:

The wheel or more accurately, the rim and spoke de-sign is quite a challenge when you look at the referenceimage and try to imagine the steps it would take tomodel it.

For a more detailed instruction, I would suggest thatyou follow my online video tutorial which explains allthe steps taken in detail. In this text tutorial I wouldlike to focus on some basics and the application of thearray modifier in conjunction with the clone tool.

Step 1 Before starting to actually model the sketchedout slices I need for the wheel and based on that whattype of meshdensity Ineed. Wherethe rims

meet, wherethe spokesmeet, wherethe holes

meet - all those design decisions should be answered as

much as possible before you invest serious modelingtime. In the following image you can see the final re-sult of that attempt. Special care was spent on creatingnice half round openings, which would, with the arraymodifier, form complete circles.

Step 2 The arraymodifier works simi-lar to the mirror tool,however beside theability to merge

matching slices to-gether, it can alsoarray elements alonga distance, line, orrotational value. Inthis case I used the rotational value utilizing an"Empty" as my value provider.

A quick calculation of 360 degrees divided by 5 slicesresults in 72 degree. My empty is thus rotated by 72degrees.

Inside the array modifierthe empty is defined asthe object and the arraycount is set to 5.

It is important besides"Merge" also to selectthe "First/Last" button aswell. This will not onlymerge between the dif-ferent slices but also be-tween the start and end

slices closing the circle.

Step 4 To finish

up the wheeldistribution,instead of dupli-cating the ob-

ject with "shift"+ "d", I clonedthe object bypressing "alt" +"d". This com-mand is called"Duplicate

Linked" andmeans that an-other 3D container is being created which howeverlinks to a shared 3D mesh data block.

The greatadvantage isthat I onlyneed to editone wheeland have thelinked dupli-

cate also up-dated in realtime as youcan see inthe followingimage.

This working method saves work time and disk spacebecause your mesh data does not increase with eachadded linked duplicate. Of course you can make alinked object a so called "Single User" by selecting the

following command: Menu > Object > Make Single User> Object & ObData.

Steering Wheel

As a note whenyou work withfaces and extrudesurfaces upwardswhile also usingthe mirror modifi-er, you need oftento delete faceswhich would beinside your mod-

el. The mirrormodifier hasno possibility toactually check ifedges of geome-try which meets through the modifier do not need tobe extruded. Inside the image you can see the faces Ihave selected and how the edge between the two quar-ter parts looks somewhat pinched. Remove those facesand the quarters will flow smoothly into each other.

Step 1 Similarly with the wheel, a method of firstsketching out basic proportions and mesh require-ments was explored. I put down an outer and innerring and tried to find a minimum requirement formesh density to beable tomodelthe wheelincludingalso theholes.

Step 2 A mirror

modifier is be-ing used to cre-ate a complete2D steeringwheel sketch.

Step 3 An addi-tional internaledge extrusionwas applied in-side the steering

wheel holes tocreate the ge-ometry which Iwould needlater to modelthe materialthickness from.

With propor-tional editingturned on, Imoved the center ring down and created a nice and

soft transition from the moved inside to the outsidering.

Step 4 With asimple straightdown extrusionthe materialthickness wasadded.

Step 5 In thisstep you can see

why the addi-tional edge ex-trusion was applied in step 3. By having the face edgesselected, a simple additional extrusion downwards cre-

ated the surface

for the hands tohold. This willmake the wheelmore comfortableto hold as well asmore stable be-cause of theadded materialgeometry.

The upper center of the steering wheel also received

some pushing and pulling adding a ball shaped dome.Step 6 To buildsome additionalstrength and du-rability to thewheel, additionalinternal struc-tures needed tobe added. I se-lected some facesbelow the wheel

and extrudedthem down.

The amount of points/faces you can work in this caseseriously depends on the grid size you started to workon in step one. If the required amount of points is notpresent you can also actually bake the subdivision mod-ifier by clicking on apply and continue working on athus finer mesh.

Step 7 To round up the styling, through push and pull-ing, the lower edge was reduced and made sharper, to

remove the bulky look. The extrusion was also con-nected to the center pipe to provide a nice flow.

IntroductionUsing a Normal Map, you canadd high quality surface detail toa low poly mesh. The effect issimilar to a Bump Map, exceptthat the Normal Map algorithmuses more channels. Simply put,a Normal Map is more accurate and looksless "painted on" than the plain greyscaleBump Map method.

Normal Maps can make a low-poly mesh look high-poly, but without the CPU strain which a high-polymesh would cause. For this reason, they are typicallyused in games where various characters and modelsneed to look awesomely detailed but without slow-ing down the in-game action. In this tutorial, youare going to use a Normal Map to make a low-polymesh look as though it is a high-poly version. Basicmodeling knowledge of Blender, including UV un-wrapping and Sculpt mode are assumed.

Outline:

You will start off with a low-poly model, whichyou will need to UV unwrap.

Once unwrapped, you will duplicate the low-poly model and use sculpt mode to create ahigh-poly copy.

You will follow a simple baking process to cre-ate a Normal Map based on the difference of the

two models

Finally, you will apply the Normal Map to thelow-poly model to see the effect.

STEP 1: Prepare and unwrap your low poly model.

My low-poly mesh is the Suzanne monkey head,

subdivided once. Su-zanne is not really idealbecause she has overlap-ping faces, especiallyaround her eyes, whichwill likely be trouble-some for Normal Map-ping. Where possible usea simple base mesh with-out sandwiched faces. Ihave applied setsmooth to her edges as this helps disguise that she

is really a low poly mesh.

Unwrap your low-poly model. A good Normal Mapdepends on a quality (well spread out) UV layout.

Make sure the low poly mesh has an image associ-ated with it from the UV edi-tor. While in EDIT mode,assign a "new image" in theUV editor as needed (andpre-save this image). Thisnew UV image is now set upand ready for baking, whichcomes later in STEP 3

STEP 2: Prepare a high-poly version.

You can make a high-poly copy of the low-poly mesh byduplicating (SHIFT-D) thelow-poly version, thenapplying multires etc.and using Sculpt Modeto add in surface details.

A few pointers...

Name each mesh(I'm calling mine

"Suzanne_hi" and"Suzanne_lo")

You do NOT need to have identically unwrappedUV maps for each mesh. Your high-poly mesh canbe a completely different model for clever effects.

When baking the Normal Map (STEP 3) it will beimportant to have both meshes in the same place;one inside the other (not side by side). Whensculpting, move the low-poly mesh out of the wayonto another layer (M-key).

Sculpting should aim to add surface detail to yourlow-poly mesh (muscle bulges, cloth wrinkles, skintextures and so forth), but don't try to sculpt exten-sions your low-poly doesn't actually have (e.g.don't grow more arms or sink big holes).

Save frequently. Sculpt mode is a heavy process,and is prone to crash.

STEP 3: Bake the Normal Map

SHIFT-select both the high and low poly models (thelow-poly should be selected last!)

Now you need to bake

(Scene (F10) => Bake options)with the following set-tings...

The Bake should be set to"normals" (not "fullrender").

Make sure "Selected to Active" is activated. This com-pares the high poly mesh against the low poly mesh inorder to work out surface displacements.

Normal space should be set to "tangent". This will gen-erate a Map that allows for the object to be animated(e.g. change rotation). Older methods could only makeNormal Maps for stationary objects where only thelighting posi-tions couldchange.

Now hit the big"BAKE" buttonand you shouldsee your newand blue UVmap generate.(I like using1024 sizedmaps for rea-sonable resolu-tion)

Save this mapwhen you aredone.

22/41

STEP 4: Apply the Normal Map to a low poly figure.

You no longer need the high-poly mesh. Simply applythe newly saved image as a texture to the low-polymesh with a certainsettings as shown...

Under Shading (F5) =>Materials (red ballicon)

Under "Map input"change the projectionsetting from "Orco" to"UV".

Under "map to" thedefault is "Col" (diffusecolour). Change this to"Nor" (normal, orbump).

To make the Map workas a Normal Map in-stead of a Bump Map,under Shading (F5) =>Texture (F6) (the leop-ard skin icon), under "Map image" panel, hit "NormalMap" and select "Tangent" from the next drop list.

Your render (F12 key) should now show the low res

model with all the bumps that the high resolutionsculpt has. This technique works well on a subdividedmesh with soft edges.

As you can see, this

low-poly mesh nowlooks very similar tothe higher polysculpted version.

The result works wellin GLSL / texturedmode (go to the topmenu "Game => GLSLmaterials" and thenshow a 3D windowas "textured"). Game Engine also works, but be sure todelete the high-poly version before hitting P or yourisk freezing up your machine.

Again, my choice in using Suzanne as a model is notideal. The troublesome brown patches can be tweakedin Photoshop / Gimp etc. but it's much easier to avoidbadly positioned faces.

So that's it. Now you can use Normal Mapping to give your low resolution meshes some high resolutionpunch, without compromising heavily on animation

render times

IntroductionIve always been a big horror fan and remem-ber the black and white movies from wayback in the day. There were movies likeThem, From Hell it Came, and Nosferatu, allof which really made an impression on me.In the case of Nosferatu, the lighting and useof shadow became as important as the titlecharacter himself.

Lighting and color always play major roles inour work as artists and film makers, whetherwe work in 2D or in 3D. When I art directed the TVanimated series Mutant League, we had to conveyteamwork and optimism in a bleak world so thelighting and colors, though muted, were oftencheerful and upbeat. My studio produced a shortanimated film called Black Zero: Mercenary Ant, fea-turing a heroiccovert operativewho rescues peo-ple. For Black Ze-ro, shadowsplayed a majorrole in hiding thehero as he infil-trates an off-shore oilplatform to res-cue a hostage.

Todays current crop of horror films, particularlythose from Japan, like the Ring, the Grudge and One

Missed Call got me all hot and bothered to makeone of my own. Im currently working on an adapta-tion of the Edgar Allan Poe classic short story, the"Tell-Tale Heart: Larynx Edition". I thought it might

be fun to kick up

the spooky a fewnotches.

The very first thingthat came to mind,once I decided todo this short film,was lighting andmood. We allknow the story butsince I plan to make it creepier and scarier allaround, I really need to think about lights, shadowsand ways to make the viewer feel like theyre in aclaustrophobic situation.

In this promo shot for the film (rendered in Blenderwith textures from Photoshop), I have the Old Manbeing slightly chewed on by a grandfather clock that

just happens to be possessed. Youll also notice theuse of another lighting technique called a gobo. Itssimply a light that projects an image such as thetree branches you see in the background.

Guide the viewers eyes with the lights, shadows andnegative space. Very rarely do we find symmetry inthe real world, so its good practice to place yourcamera so that the focal point of your image or shotis never in the center.

Horror movies generally arent very scary if you canfully see the monster coming down the hallway.Granted, there are some creatures like the Alien andany variety of Jasons, Michael Myers, etc, that willstill make you straight out run like a track star. Butin most situations, if turn those lights down really

low, that monster could be a kitten and still makeyou run for the hills.

Conveying Moods


24/41

Lighting can also be used to great effect when com-

bined with proper staging, The goal is to cover up acreature even further, thus creating the effect of dread.Take a look at films like The Grudgethe main attrac-tion; a ghost name Kayako is typically only partially vis-ible due to the long black hair covering her face. Railson the staircase, a bathroom stall, her sticking halfwaythrough a wall, etc., also often obscure her. In the raretimes we do see her fully, she is in or surrounded byshadow (the hallway in the hospital in Grudge 2, forexample).

So lighting is just part of the equation. Filmmakersmight also wish to employ what is called a Dutch An-gle, where the horizon is slanted to one side. This shotis used to cause disorientation in the viewer or to putthem in the actorsplace. Theres re-ally nothing scar-ier than themonster comingafter you as youlay helpless on theground in the

woods. Here youcan see the use ofboth the Dutchangle and lowerillumination onthe grandfatherclock.

The simplest thing you can do to show that somethingisnt quite right in a scene is to defy the laws of nature.Our eyes and our senses are used to light sources natu-

rally coming from above. We open our door to get themail and we expect the sun to be in the sky (this, ofcourse, also has to do with just how much beer youmight have had the night before). When we wait for a

taxi late at night we expect the light to come from the

moon, neon signs and the street lamps.

By placing your light source at an unexpected angle,say below a persons chin, were immediately thrownout of whack. Lighting a subject from below makes usthink about where the light is coming from. Low lightsare great to convey supernatural forces or even theground opening up beneath our feet.

So were going to take a look at how you can convey asense of dread, of dark power, with the lights in Blend-er. The following is just one of several methodologies

when it comes to lighting. Some people adhere to the3-point lighting routine (Key, Fill and Rim), whereas Iuse lights quite liberally in many situations. Although Idont stick with 3-point lights, I do typically start mylighting with 3 to set the mood. From there Ill add asmany lights as necessary to emphasize parts of certainmodels or things I want the viewers eye to catch, likethe details in a clock face.

One potential pitfall you can try to avoid is placing allof your lights down right away. Ive discovered that

endless amounts of time can be wasted tweaking lightsuntil you get them to look the way you wanted.

25/41

What I tend to do is to start with just one lamp and

modify it until Im happy. Ill move the lamp. Then Illadd the next lamp and put the original one on its ownlayer.

I add one lamp to the scene and modify its settings un-til I can make out the edges of the models. This type oflight is called a Rim or Back light because its role is topush the models away from the background so theydont blend with other background objects. I normallystart with the Rim since its usually the most difficultfor me to adjust in a way that makes me happy.

Anyone whos familiar with the original story knowstheres an old man with a crazy eye, but there sure asheck aint a clock that will eat your face off. It was im-portant that the clocks arms had a very otherworldly

feel to them so I placed them and their lights on theirown layer. With these lamps set to only illuminate theitems on the same layer, I avoided having these lightsaffect any other objects in the scene. You may find

placing specific ele-

ments and theirlamps on separatelayers a very benefi-cial way to achieveotherwise difficultillumination scenari-os. I chose colorsthat one would nottypically use to illu-minate a room sothey would feel out of place.

26/41

Just like the clocks

arms, the faceneeded special atten-tion. I placed 3 lightsvery close to the vari-ous parts such as thenumbers, the entireface and all of theextra gold details.Making sure theviewer sees all thisgold on the grandfather clock communicates the Old

Mans wealth.

The ceiling lamp was

the easiest of themall to place since its

job was to simplyilluminate the tex-ture on the wall anda small spot abovethe clock. This lampssecondary role wasto provide a smallpunch so the clockstood out a bit more from the background.

I hope you enjoyed seeing how I tend to work and theprocess behind the choices I make when directing and

planning a film. Keep in mind that what we are creat-ing is art, so try to find a balance between the technicaland creative sides of the process

IntroductionAs technology develops further andfurther, some objects that are be-ing used every day by millions ofpeople suddenly become function-less. Then, all of a sudden, they be-come symbols, artifacts of acertain episode of time. Thatswhat happened to the good oldcassette. It reminds one of youth,good music, mix-tapes, being onthe road and hanging around infront of a radio waiting for somespecial song with your finger on

the record button

Lets celebrate the memory of this ancestor of allportable audio devices and animate the winding/unwinding of a cassette tape!

In the script I'm using this to get the X Loc and YLoc values of each object out of their final desiredposition (b) and the center of the gazebo (a) which Iget from an empty object that I can even animate

with oscillating movements to get interesting ef-

fects, check lines 68 and 78 for final implementa-tion.

Setting up the Scene

First of all, set up a basic studio-like scene. I wantedthe cassette and tape to be stretched out on whitepaper. Thus, I added a plane and gave it this Materi-al: Slightly grey colour, no specularity and a proce-dural marble-texture (noise-depth: 4) affecting thenormal value. Two spot-lamps with somewhat old-fashioned buffered shadows, above all a sun and aforth lamp close to the floor illuminate everything.

No tape without a cassette, so lets start with that.First, we need a simple cassette-sized box, with aBevel-Modifier to get some rounded corners.

Cassette Tape



28/41

Enough modeling,

lets just add a pho-tographic texture ofa cassette. I took apicture of one Ifound at myparents phonoshelf. Pretty retro,hmm?

As this scene willmostly be shotfrom a bird's per-

spective, the lack ofcomplexity of thecassette won'tbother us.

The Tape

Now its time for thetape. First add a path.

Grab and move thepoints and add somenew using CTRL-LMB to

define the word/ phrase/ symbol you would like to lay

out with tape. Remember: Sharp edges and crossingsare quite unlikely in reality, so better avoid that (Trustme, I made some studies with real tape;).

It is useful to write out the word without lifting yourpencil off the paper first!

I picked up the word mix to celebrate the ancient tra-dition of creating elaborate mix-tapes. Finally, the endsof the path should touch the edge of the cassette. Dontforget to name the path, like mix.


byBen

noWagner

29/41

Well, thats the

path, now weneed the tapeitself. Add aPlane and deletetwo vertices.

Select the re-maining two andpress Subdivide(->Find it in theEditing buttons)about 8 or 10times. Now withall vertices beingselected switchto front view andextrude themand give themthe height ofabout of thecassette.

Next, we need two modifiers.

First, add the Sub-Surf modi-fier and adjust it as you like.Second, add the Curve modifi-er. Fill in the name of yourPath (in my case mix).

Now, with thepath selected,click on CurveS-tretch in the Ed-iting buttons.The result will be

shocking at first!Chaotic lines allover the place!

Thats because somethings wrong with the position of

the mesh-tape object. Select the mesh-mess and move italong the y-axis until the mesh perfectly stretches alongthe path. You can increase the Sub-Surf value of themesh if it looks somewhat edgy.

Animating the tape

Now, everything is set up tobegin with animating thescene! First of all, we turn thePath into a Softbody. Select the

Path, choose the Objects-but-tons and than the Physics-but-tons. There, enable theSoftbody-function. Set the fric-tion-value to 2 and the gravityto 0.0 as the tape operates on a plain surface anyway.Finally, disable the Use Goal option.

Next, add an Empty just close to the ends of the tape,somewhere inside the cassette. In Object/ Physics-but-tons, with the Empty selected, choose the Harmonic-Field. There, set the

strength value to 0.6 andgive Damping a 0.6, too. AsFall-off-value, choose 2.1.

Activate maximum andminimum distance by click-ing on the small use-but-tons and enter thefollowing values: MaxDist:3.46, MinDist: 0.30. Youmay change those values to

your liking and even move

the harmony-empty aroundto find the best settings for

your scene.

30/41

Thats it! Now press Alt+A and watch your laid out tape

getting wound up! You might notice some crazy behav-iour of the tape close to the Harmony-empty. Try tokeep this whirling around to be happening inside thecassette. Move the Harmony-empty, or change its set-tings to handle this issue. You want the tape to emergeoff the cassette? Just render your clip. Then, within theblender sequence editor, choose reverse and the taperevolves the other way round

IntroductionIt has been told time and againthat it is the little things that willhelp make an event more accepta-ble to your audience. To that effect,applications like Blender havecome equipped with many simula-tions, material settings, and nodesto create things like smoke, fog,and lighting that audiences canfind acceptable for a scene or eventin a story. Sometimes though,these effects require resources thatare above what the general hobby-

ist can put together.

But that rarely stops the audience from asking for "alittle extra."

One such requirement for "a little something extra"occurred when we were making a short reel called"The Surprise Attack." The animated demo was in-tended to be short, depicting just one "awesome"

moment in time in a larger concept.Specifically, the moment depicts an event of unex-pected danger when a seemingly normal helicopterflies into view of a lone human person only for thesaid vehicle to shift and change into a metallicmonster that literally takes on weight and falls outof the sky, landing on a rooftop helipad and actinggenerally menacing.

The reel looked fine but a little extra something wasmissing.

"There should be dust. When it comes down. That'sa lot of weight so it would be nice for dust to getkicked up from the floor." said one member of mytest audience.

I agreed of course with the assessment. It made

sense. The artist in me definitely felt the sameabout that single piece of action. But it was nosooner than I had agreed to add dust, that I beganassessing how tricky it could be to simulate it.

Traditionally, Blender comes equipped with thingslike Volumetrics and Particle simulations. I had seena few clouds and fog done to good effect with thesesystems. But in almost all cases the render timeswere very significant. As a novice with only mid-range equipment and no render farm, doing it thisway was out of the question.

But I really wanted that cloud of dust. I alreadyknew some members of the potential audiencewould notice the need for it and I didn't want todisappoint. I also knew that if I could somehowsolve this concern, the same method could be usedto derive other similar effects in future projects.

Having ruled out using Volumetrics or Particles, Idecided the dust would have to be done with somegood old-fashioned Texture Projection. This wassomething I had seen used for explosions andsmoke in old video games from quite a few yearsago, but getting it right was still kind of tricky. I wastrying to pass off a cardboard cut-out for what hadto appear as an effect with volume.

To achieve the effect I used some old clouds texturemaps I had made in my stock and UV mapped it to aset of curved sub-surfed meshes that were modeledto appear like waves with their mid sections slightlyprotruding outwards.

Dusting off a Surprise



32/41

The mesh shape appears below.

And the materials settings appear below

Once I was convinced that the dust hadthe right "look" all that remained wasto animate the mesh

by keyframing Location, Rotation, andScale so that the dust clouds started invery small size, grew larger and fannedout in a nice way for the camera.

Finally, we tweaked the Dust cloud'sAlpha setting so that the cloud starts

out totally invisible, becomes opaque,and then dissipates back into nothing-ness as the mesh fans out.

The final effect, though not spectacular,performed to a satisfactory level withmy test audience and appears to haveescaped criticism, at least for the timebeing as I write this. The impact to

render times with this effect was also negligible. Thissame method can be used for other similar "background

effects" such as animated

fog, smoke, gun fire, ciga-rette smoke, and to a cer-tain extent it can evenmake do for halos onlamps and light fixtureson a set by using the rightmaterial.

Dont forget, its not al-ways about how complex

your visual effect was to

make, many times its justdown to what your audi-ence is going to actuallysee.

1- What inspired / or led you to start Blenduca-tion?

In retrospect, it seems like my entire life has pre-pared me for this endeavor.

Identifying the Problem

I started working with Blender and found lots ofgreat tutorials in PDF, video and HTML format bysome amazing people. When I watched Bassam'sChicken Chair (Can be viewed here) I was hooked.I had to learn more. The problem was getting an-swers to a particular problem. It was such alengthy and almost impossible task.

I thought, Wouldnt it be great if I could just askthe person that made that tutorial? It would saveme so much time and effort. I am still waiting forGrayBeard to reply to me.

The Birth of the Idea

I attended the Siggraph show in Boston 2006 afterbegging Ton to let me work the booth at theshow. With David Millets help, Ton agreed to letme. After meeting Ton, Bassam, Andy, David Milletand the many other BlenderHeads at the Boston

Siggraph, I discovered that Blender was not justabout the 3D graphics, it was a community of peo-ple from all over the world with the same passionto create and help others create.

During that show I spoke with Bassam at length

about starting a Blender User Group. From thatdiscussion Blenducation was born. Though it wasjust a seed of an idea, it had legs. The name Blend-ucation was coined by Petri Rantanen AKA Falgor.

After many hours of talking with the great folks inthe IRC channels I was able to fine-tune the idea toLive Blender classes via a Web Browser. Now aftertwo years of very hard work and many hundreds ofhours, it's here.

2- Introduce yourself and tell us a little about yourBlender experience?

My name is David Hickson. I have been learningBlender from the community for the last 3 years,and I am still learning new things every day.

How I found Blender

I came across an article in a Mac World Magazineissue a few years ago and it had some informationabout Blender. I immediately went to the web site,downloaded the application and jumped right in. Isoon realized that I was spending more timesearching for resources to learn how to do the sim-plest processes than actually working in the pro-

gram.There are tons of good tutorials out there, but forevery one good tutorial, you must weed throughlayers and layers of bad ones (at the time I had afull time job and you just cant be surfing the en-tire Internet looking for new tutorials when youhave a real job). So anyway, once you have foundone that covers the topic, its usually incomplete orsome small part has been over looked with the pre-sumption that, you should know that. Thisproved to be very unproductive and frustrating. Ifound myself saying, I just want to model! And to

make matters worse I would jump from one sub-ject to the next and miss huge parts of what wasimportant.

INTERVIEW: David Hickson - Blenducation 35



36/41

During one of my Blender Ninja quests for knowl-

edge, Bart pointed me in the direction of IRC andwhat a great resource that was. So many amazingartists just sitting there waiting to help, except myunderstanding of Blender was so bad I didnt evenknow how to ask good questions. Without know-ing the basic terms of what I was doing and doingwrong I only frustrated people in IRC (I still do attimes, sorry ZanQdo). I have since put away mypaintbrushes and clay and now hold a mouse orWacom pen instead.

3- Classes are currently being offered for free. Willthere be fees for future classes, and if so how much

are you expecting to be charging? Will there still befree courses as well?

There will always be FREE classes offered at Blend-ucation to introduce people to Blender and to getthem started with Blender. Think of it as the wel-coming committee to the Blender Community.These classes will have an open question and an-swer period throughout the class to help peoplefind great resources and new challenges.

There will also be a pay-per-seat program set up foradvanced classes. The prices will be set up on a

tiered system. The more advanced the class, themore it will cost.

Tier one classes will be $5US and $10US per seat.

Tier two will be $10 and $15US per seat.

Tier three classes will be $15 and $20US per seat.

If a class runs three nights and is a tier three class,it will be offered at a discounted seat rate.

4- Not only are you offering Blender classes, but youhave extended an invitation to interested instruc-

tors to use Blenducation to teach/offer classes aswell. Can you tell us a little about how to get in-volved as an instructor at Blenducation?

Yes, I have begun to invite some power Blender us-

ers to become instructors at Blenducation andmany of them have become part of the team.Among them is David Millet (US), an amazinglyskilled gentleman and a great mentor.

Sebastian Koenig (Germany), whose works aretruly amazing. He makes it look so effortless.

Then there is Mr. (Jonathan Williamson) Bomb(US), whos human anatomy could have landedhim a gig as a Doctor, but the difference is thatdoctors only know the parts and Jonathan canmake them.

OOPz AKA OOPz (England) is a very well knownBlender artist that specializes in the world ofBlender's Game Engine. His expertise in the BGEwill be a key area of interest to many Blender art-ists.

Daniel Salazar AKA ZanQdo is a straight shoot, nofluff educator, if you are lucky enough to get intoone of his classes you will come out a better artist.

Do I have more time? Ok, there is Goeland86 (US),who long ago invited me to join him on a projectof recreating a historic air battle. He is a very gra-cious person with extreme patience.

And then there is Jean-Sbastien (Canada (AKAECKS)) who has few equals when it comes to me-chanicals, like cars and bikes.

Also there is another good friend of mine that isknown as Super3Boy (US) infamous in YouTubeworld as the boy prodigy of the Blender communi-ty. Let me assure you his skills and knowledgedont end at Blender, have you checked out hiswebsite?

The list goes on to include our most influentialBlender rigger Mr. Mancandy himself, Bassam Kur-dali (US).




37/41

I was testing some stuff one day and invited him in

to check it out and it froze up his laptop. If he for-gives me he may do a couple classes.

What would this list be if I had not contacted andasked Roland Hess? That is correct, I am so excitedthat Roland has offered to give a couple of lecturesfor us.

Also on the team is; FWEEB, MFOXDOGG, Paulo Cri-tovao, Templa Edhel, and many others joining us tohelp the community grow.

A more accurate and updated list is on the site at

http://blenducation.org/wordpress/presenters/ . It istheir commitment that strengthens my resolvethat the Blender community truly does care,thanks guys.

Qualifications

You dont need to have a degree to teach classes atthis point, although most of the very advancedclasses or Tier three classes will be taught byBlender Foundation Certified Trainers (BFCT). Thefree classes are great way to learn how to teach anonline class.

Just submit a few renders and tell us why youwould like to be on the team. If you are selected

you will be notified and we will set you up yourvery own blog Page. In addition to the blog pageand your own gallery, all the instructors at Blendu-cation are offered free passes to other instructorsclasses. This allows the presenters to grow theirskills and sharpen their Blender knowledge fromone another.

5- You mentioned setting up Certified trainingguidelines along with the BF Certified trainer pro-gram. Has any progress been made on that?

Yes in fact, I have spoken with a couple of key peo-ple on the BFCT board and we actually have a fewinstructors that have the BFCT credentials now.

I am waiting to see what happens in the next cou-

ple of months with the BFCT program, I have beentold that some changes may take place. My hope isto layout a Direct path to Becoming BFCT pro-gram that will provide all the criteria one needs toknow in order to submit your work with confi-dence to the BFCT board and become accepted. Iam working closely with them in order to designthis learning path. Obviously, not everyone will ob-tain their BFCT nor will they want to. Some people

just want to learn more at their leisure. So there isno pressure.

6- What are your future goals for Blenducation?

The short-term goal is to add to our team of in-structors so we can help users all over the worldbecome more marketable in the industry. It has tostart somewhere. It is true that a person with nodegree gave the very first diploma.

Next we hope to add a testing center that will helpthose of you that wonder where you need to studymore in order to go after your BFCT certificate or

just to brush up on those rusty skills
