1/9

First dividing the bike into layers shown on the below page and templating parts that are notneeded at this point in the process, so other parts of the bike do not interfere with the currentpeace of geometry being worked on within the scene.

Then named the layers according to that part of the bike by reference photographs also givingsome indication of the types of textures needed for the final Render.

Picture 7

Picture 3 has a leather texture taken from a desk chair taken with a Fuji Film FinePix

Camera.

The textures of the pictures 4, 5, 6 were created in Photoshop with the use of theGradient Tool then applied versus types of Texture Effects from the Filter Effects Menugiving a bit more of a pattern.

The bottom half of picture 7 showing uvs with texture for the frame of the Bike wasrotated to better match the same Direction of the gradient for both sides of the bikeframe.

The tex ture on the side of the bikes fo lk does not seem quite right at this moment, as it looks like it sslanting, although the clogs and bike chain seem ok in a shadowy grey that is noticeable in the pictureRender above.

Also having the Speedy Logo in white made in Photoshop sticks out well from the rest of the Frame of the bike that is in a textured grey gradient.

Below is the first try of projecting a photograph onto geometry, one thing that is most noticeable is theshading on the top part is much more saturated, showing the cut off point of where the other Geometry isoverlapped.

So the top pece of the geometry and its applied Shader was changed to match the shade of the bottom half making both parts look as one photograph.


6/9

Also having the bottom plain level with the placing of the bike has made the bottom half of the photographslanted slightly which is noticeable looking at the grass of the picture above, looking at the whole bike fromthe above angle also makes the bike seem smaller than it should be.

One other noticeable thing is the darkness of the bike as lighting has not been applied to the scene yet.

Then changing the direction of the bottom plain to match the position of the top plain evening the picture out

making the bike look like its actually touching the ground of the photograph.

Rotating the bike so its looks more like its resting in the fence, applying a Directional Light shows the colours of thebike much better with the white to grey gradients more clearly shown above compared to the two pictures on theprevious page.

Below is the original photograph using in the Projection as the camera Perspective 1 that was zoomed in closer and

rotated slightly gaining a better close up of the bike.

Also a volume light was applied for better illumination.

8/9

The other picture above I think would have had too much sun shine if the bike was placed atthe front side of the fence.

Although as an improvement it would have been good to match the direction of the bikeshadow pointing in the same direction as the suns rays and shadows of the fence would havebeen a challenge.
