Introduction

Before attempting to create a scene it is important to understand global settings pertaining to any scene that

will make modelling more efficient together with settings that pertain to individual scenes and stages in scene

development. This tutorial explains Viewport Configuration options, Scene Settings and basic MAX / VIZ

Configuration.

Viewport Configuration

MAX / VIZ uses viewports to:

Navigate around the project and display different parts in different viewports

Transform objects on different planes when using the viewport reference coordinate system

Display object elements in a variety of ways to aid modelling

2/24

At this stage in Key Fundamentals it is important to understand that in MAX / VIZ you have to deal with two

types of rendering.

1. What you see in the viewport, or Display Rendering

2. What you produce as an output image or animation or Output Rendering

Open Render types.max. This scene contains a box and a tree. What you see is the Display

Rendered

On the Main Toolbar press Quick Render This produces an Output Rendered image

The following two sections explain how to alter certain display rendering and output rendering settings to help

you model efficiently

The Viewport Menu and Viewport Configuration dialog are used for altering the display render as shown

below:


3/24

Viewport Menu

To Open the Viewport Menu right click on the viewport text (eg'Perspective') to the top left of any viewport you

need to configure. The following menu appears. Commonly used items are shaded in the image below:

Smooth + Highlight / Wireframe

Open Viewport configuration.max. This scene contains a tree on a box object

Viewport Menu > Smooth + Highlights - the objects are now displayed as Smooth and

Highlighted

Press Wireframe - this reverts back to Wireframe display mode

Explore Others - these other options are sometimes used as a modellings display aids

TIP: Toggle between Wireframe and Smooth and Highlight display mode frequently when modelling. Usually

only one viewport (two at most) are kept in Smooth and Highlight mode when modelling to save on system

resouces

Keep the same scene open to explore the next three options


4/24

Show Grid

Viewport Menu > Show Grid - notice the grid is turned off. Practice turning the grid on and off

Grids are a modelling aid, often used to 'snap' vertices and even objects to when creating a scene. However,

they have limited use in landscape work due to two main issues

1. A large proportion of surface boundary detail and object positioning is done in AutoCAD

2. Grids tend to complicate the view when working with many landscape surface meshes

The grid displayed in this scene is the default Home Grid and all geometry is created by default at the level of

the home grid. However, grids can be created, moved and used as modelling aids

TIP: Use the Show Grid toggle as a visual aid at the start of modelling to quickly view how far a surface or

object is above 0

Show Safe Frame

Viewport Menu > Show Safe Frame - use this toggle to show what will be rendered in the

Output Render

NOTE: This is usually kept off and just used as a reference when needed so that the modelling viewing area is

maximised

Viewport Clipping


5/24

Viewport Menu > Viewport Clipping This displays the viewport clipping controls

Move the bottom control gently upwards to see the objects in the scene clipped

TIP: This can be a useful technique for cutting into the landscape to show a section view

Texture Correction

Open Texture correction.max. The scene has a box object (zero Z value) with a flag texture

assigned to it. Notice that the texture looks badly tiled

Viewport Menu > Texture Correction - the texture now looks as it is meant to look in the

Perspective viewport

NOTE: MAX / VIZ defaults this to Off to save on system resources. Paving materials are often better viewed in

the viewport with this set to On and unfortunately this has to be set every time the scene is opened

NOTE: If another graphics driver is selected other than the Software Z-Buffer option, the texture may display

correctly in the viewports


6/24

Views

MAX / VIZ has a number of different default views to choose from. Briefly explore the different views available

(apart from Camera View)

Open Viewport configuration.max

Viewport Menu > Views > User

Viewport Menu > Views > Front

Viewport Menu > Views > Back

Viewport Menu > Views > Top

Go as far as Right and practice toggling between the different views

NOTE: Views are changed in other ways later in the tutorial

Viewport Settings

Before starting modelling certain environment settings in the scene need attention together with some viewport

settings

For the background colour of output renderings (as oppose to the display render) and ambient light the

Environment dialog is used. For display options to aid the modelling process the Viewport Configuration

dialog is used. These dialogs are both used in the initial setup of a scene

Render Background Colour and Exposure Control

The background colour of output renderings needs changing as the default colour is black and for now

Exposure Control needs setting to 'no exposure control'

Open Environment.max
http://www.cadtutor.net/tutorials/3ds-max/scene-setup.php#topnavhttp://www.cadtutor.net/tutorials/3ds-max/scene-setup.php#topnavhttp://www.cadtutor.net/tutorials/3ds-max/scene-setup.php#topnav


7/24

Press Quick Render Note that the output render has a default black background and the

scene objects are rather 'washed out'

Rendering > Environment - this displays the Environment and Effects dialog

Click on the Background Color swatch and move the Hue selector to top blue and the

Whiteness down


8/24

On the Exposure Control rollout change the Exposure control from the default Logrithmic

Exposure Control to no exposure control. Exit the dialog

Press Quick Render - notice that the output render has a light blue background and the objects

are not 'washed out'- better for test rendering. However, the scene does now look a little dark.

The next step is to alter the ambient light colour in the scene

Keep the scene open for the next stage

Ambient Light, Global Lighting Level

Ambient light is light that is reflected from all objects in the real-world environment. For starting a scene and to

add a lighter ambient tone to the scene in both the display and output renders, lighten the ambient colour as

described below:

Keep Environment.maxopen (if not open again and change the background colour)

Press Quick Render Note that the objects in the scene look dark

Rendering > Environment - this displays the Environment dialog


9/24

Move the Whiteness slider down to just below half way then exit the two dialogs. Notice that the

objects in the viewports look brighter (if default lighting is not used in the viewports)

NOTE: The objects in the scene will not look brighter if default lighting is used in the viewports. The setup is

changed to not use default lighting a little later in the tutorial when the ambient lighting effects can be seen in

the viewports

Press Quick Render - notice that the output render looks much brighter

Change the Global Lighting Level to 1.2. - notice that the output render look even brighter

Practice altering settings for Background colour, Ambient light and Global Lighting Level,

testing the effect using the viewport display and Quick Render

Keep the scene open for the next exercise to determine viewport layouts

Viewport Layout

The layout of viewports are a personal preference. You can change the layout at any time in the Viewport

Configuration dialog


10/24

Open Environment.maxif not already open and adjust the background colour and ambient light

settings as before

Viewport Menu > Configure - on the Viewport Configuration dialog select the Layout Tab

From the viewport layout thumbnails select a new layout

Left click in any of the viewports in the viewport image to display a dropdown menu and select

another view from this menu

Press OK to implement the viewport layout

Practice changing the viewport layout, then change it back to the one displayed in the image

above

Changing the View in the viewport

Right click in any viewport to make it active (the active viewport will have a yellow border)

On the keyboard type T for Top, L for left, F for Front, P for Perspective, U for User

Force 2-Sided


11/24

The Rendering Tab of the Viewport Configuration dialog is where you use three particular settings that aid

the modelling process (Force 2-Sided, Default Lighting and Shade Selected Faces). Force 2-Sided is

explained below:

Open Force 2-Sided.max. This scene contains a model of a bamboo plant

Notice in the User viewport that some stems and leaves appear to be missing

Press Quick Render - notice that in the output render some stems and leaves are missing.

This is due to the fact that MAX / VIZ by default only renders one side of any face (covered in a

later module) in the viewport display and output renders. With landscape work, using objects

from various sources and geometry from AutoCAD you often need to tell MAX / VIZ to render

both the display and output render as Force 2-Sided. This is because the imported geometry

often has faces which face the wrong way

NOTE: MAX / VIZ renders one sided by default to save system resources, so if the scene does not need Force

2-Sided leave these options checked off

NOTE: As well as changing this setting in the viewport and render settings, you can configure any material to

display 2-Sided. This is covered in 'KV04 Lighting, Materials and Production'

Right click in the User viewport to make it active

Viewport Menu > Configure - on the Viewport Configuration dialog select the Rendering

Method Tab

Rendering Options group > Force 2-Sided


12/24

Press OK - notice that the bamboo in the User viewport now displays all stems and leaves,

although in the other viewports the display rendering is still one-sided

Press Quick Render - notice that the output render is still missing faces. This setting is dealt

with later in this tutorial when you look at output render settings

NOTE: On the Viewport Configuration dialog on the Rendering Method Tab notice that you can apply any

changes to all viewports under the Apply To groupsection

Default Lighting

MAX / VIZ provides default lighting unless a light object is inserted into the scene. Creation of real-world

lighting often happens later in the modelling process. There are options, however, to alter the default lighting in

the scene

Open Default lighting.max. This scene contains a tree and a box

Viewport right click menu > Configure On the Viewport Configuration dialog select the

Rendering Method Tab

Rendering Options group > Default Lighting

NOTE: When having inserted lighting objects later, you may find that the basic lighting effects are not shown in

the viewports. This is because you have left the default lighting options on. Turn these options off when using

MAX / VIZ lighting objects


13/24

Shade Selected Faces

The last main setting in the Viewport Configuration dialogis the option to shade selected faces. This is so

you can see them whilst modelling in sub-object mode

Open Shade selected faces.max. The scene contains a simple box and the viewport is in

wireframe mode

Viewport Menu > Configure -on the Viewport Configuration dialog select the Rendering

Tab

Rendering Options group > Shade Selected Faces

Press OK

Select the box by left clicking over one of the lines

Modify Panel > Editable Mesh - click the + sign to the left of this text

Select Face

In the viewport select one of the sides of the box and notice a red triangle appear. This is a

selected face that is displayed with 'Shade Selected Faces' turned on

Scene Settings

The following scene settings need attention before starting the modelling process:

Configure Paths

MAX / VIZ references many asset files such as images used in materials, photometric files amongst others.

Part of the setup of a scene is to review where files are kept and if needed configure the file paths for these

assets. You can also tell MAX / VIZ to start looking in certain folders for AutoCAD drawings and scene files etc

Customize > Configure Paths > General Tab


15/24

On the General Tabselect the particular path needing configuring. The main paths that need

configuring in any scene are highlighted in blue. For this exercise you will configure paths for

scenes and import of drawing files, configuring MAX / VIZ to look in your training files folder

Select Scenes

Press Modify and on the next dialog and navigate to your training folder containing relevant

scenes

Press Use Path. This new path appears in the General list

Repeat for Import, this time configuring the path to your training folder containing relevant

AutoCAD drawings - now MAX / VIZ will start looking in these folders when opening tutorial

scenes and tutorial drawings for import

Configuring bitmap paths

Customize > Configure Paths > External Files Tab


16/24

Press Add - navigate to your training folder's 'Maps' folder and press Use Path. This will make

sure that MAX / VIZ will 'see' the bitmaps used in the tutorial scenes

NOTE: Whenever a warning dialog appears showing 'Missing Maps', this means that either the maps (usually

bitmaps) do not exist on your system or that the external file paths need configuring on your computer.

Archiving a scene makes sure that all referenced files such as bitmaps are collected with the scene in one zip

file. When opening the scene on another computer it is common practice to configure paths to the bitmaps so

that the scene can 'see' them

Spinner Snap

Spinners are prevalent everywhere in MAX / VIZ for quickly changing values in settings. To explore the correct

way to use spinners and the extra need for adjusting spinner snap work through the following tutorial

Open Spinners.max. This scene contains a simple box that you will parametrically change its

height, length and width using spinners

Select the Box01

Modify Panel > Parameters rollout - look at the spinners for Length, Height and Width

In the Height value box type 20 then Enter - the box's height is changed to 20

Use the Length spinner, clicking with single clicks to increase or decrease the length

Notice that stepping up or down incrementaly takes the value up or down in 0.5, or 1 intervals. Usually, if

accuracy is needed, then the 'spinner snap' needs altering to suit

Left click over a spinner and hold to speed up the changes


17/24

Left click and drag the mouse up or down to affect the changes very quickly

To alter Spinner Snap

Customise > Preferences > General tab > Spinners

Exit the Preferences dialog and use the spinners again. The increments will be 0.01

Notice on the Snaps Toolbar the end button 'Spinner Snap' is depressed. When needing to use Spinner Snap

for more accurate input make sure that this button is depressed (this actually checks the 'Use Snap' checkbox

on the Preferences dialog)

Render Settings for Modelling

Before modelling configure some basic render settings for carrying out simple initial renders whilst modelling

Rendering > Render

Common Tab


18/24

Check Single Frame

Choose 640x480 initially. Output size depends on how fast and at what detail you need to

render and can be increased dramatically when you need high resolution images or movies

Check Force 2-Sided

Renderer Tab


19/24

Mapping and Shadows checked

Antialiasing and Filter Maps checked

Raytracer Tab


20/24

Uncheck all Raytracing options

Uncheck Show Progress Dialog and Show Messages checkboxes

NOTE: When rendering, often a Raytracing progress dialog pops up even if these settings have been made.

This is due to the use of Raytrace materials which MAX / VIZ by default has in the Material Editor. This can be

stopped by making sure that the Material Editor just displays Standard Materials and no Raytraced materials

(unless needed) are used in the scene. Landscape scenes can do without raytraced materials unless needed

for particular effects. There is a 'trade off' between the use of these materials and the annoyance of messages

and rendering time. Ref: 'KV04 Lighting, Materials and Production' for more information regarding Render

Presets and changing the types of materials in the Material Editor. At this stage in Key Fundamentals the

above settings will do fine

Press Render to render the active viewport

Press the Quick Render icon to implement output renders with the current settings and without having to open

the Render Scene dialog

MAX / VIZ Configuration


21/24

In order to make modelling more productive and the viewport display easier on the eye, a few elements of the

interface need configuring. You can even save your own interface in a CUI file

NOTE: The changes described in this section apply to all new and saved scenes

Viewport Background Colour

It is important to make the background colour of the viewports as comfortable to the eye as possible. Unlike

AutoCAD 2D work, the 3D environment requires visual depth and most modellers choose a mid grey

background colour. Make it a habit to change the tone of the viewport background to suit the task at hand

Right click on a grey area on the Main Toolbar

Select Customize

On the CustomizeUser Interface dialog select the Colours Taband under Elements choose

Viewport Background

Click on the colour swatch and pull the Whiteness slider up or down to change the tone of

grey

Close the two dialogs and notice that the viewport background has changed


22/24

NOTE: MAX / VIZ is extremely customisable. Explore this dialog to see just what can be changed. Most users,

however leave the interface as default apart from the viewport background colour

Toolbars

A toolbar are a handy place to store your favourite commands. These are configured again in the Customise

User Interface dialog

Open the Customise User Interface dialog

Under Group choose Main UI (for example) and under Category choose All Commands

Press New and name the new toolbar in the pop up dialog

Drag and drop commands from the Action Window onto the new toolbar

If the command has an icon next to it in the Action Window then this icon will be displayed. If

not, the text will be displayed. The icon can be edited by right clicking on it and choosing Edit

Button Appearance (ref MAX / VIX help)


23/24

When the toolbar has been created elect to show or hide the toolbar by selecting it in the dropdown list and

checking or unchecking the Hide checkbox

Undos

Change the number of undos available thus

Customize > Preferences

This is usually defaulted to a low number to save system memory

NOTE: Modern computers can cope with many more undos than the default 20

Modifier Button Sets

Modify Panel > Configure Button Sets icon > Configure Modifier Sets. This opens the

Configure Modifiers Sets dialog

Under Sets type in a new Set Name eg 'General Modelling'


24/24

Change the Total Buttons amount to 6

Under Modifiers choose a modifier and left click and drag onto one of the buttons to either

replace an existing modifier or to place one on an empty button

Press Save and then exit the dialog

Press Configure Button Sets icon again and on the menu notice that the General Modelling

set has been added to the list.

Select any of the Modify Button Sets to display the appropriate Modify Buttons (a tick appears

next to the current Modifier Set)

Elect to show or not to show buttons by selecting Show Buttons

CUI Files

MAX / VIZ allows you to save your own interface in a CUI (Customer User Interface) file. This file has a .cui

extension and you can load your own customised interface on any computer running the MAX / VIZ

Open the Customise User Interface dialog

On any of the tabs press Save

Save the CUI File to your training folder

Press Load - select 3dsmax7/UI/Default.cuiand Open - notice the Interface change

Press Load - load your save CUI File to carry on working

TIP: Keep a copy of your CUI File on disk - handy for using MAX / VIZ on other computers
