Materials

We will now create our own material. Open the QS_Material.c4d ﬁle. You can see in the Object Manager to the

right that the object does not yet have a texture applied to it. Click on CREATE/NEW MATERIAL in the Material

Manager at the lower left.

A standard material has been created. If you click on this material its properties will be made visible in the

Attribute Manager to the right. In the Basic tab you can determine which channels should be activated for this

material. Go ahead and activate the Bump channel. As soon as you have done that a new tab will appear in the

Attribute Manager for the Bump channel. Now click on the Color tab and load a texture into the material by

clicking on the small arrow next to Texture. Choose Load Image and load Iristexture.jpg.

In the mini-preview of the Material Manager at the lower left of your screen you will see the texture displayed

as soon as it has been loaded. This gives you a good overview of the materials being used in the scene.

Repeat this procedure for the Bump channel and load Iristexture_bump.jpg into the channel. This JPEG

contains the grayscale version of the iris texture which we need to create a relief effect for the surface. You

can also choose Filter (click on the small light gray arrow next to the word Texture in the Bump channel) and

load the color texture here and set its saturation to –100 %. This saves you from having to load a second

image. The bright areas of the image will later appear to be raised on the object and the dark areas of the

image will appear to be somewhat indented.

A true deformation of the object will only take place in the Displacement channel. The Bump channel does not

alter the polygon’s surface but uses an optical illusion to give the surface its structure.
