Texturing 101

Aging a can using texture maps By Dave Wilson
A key to realistic 3D animation is in the texture maps. While pristine textures often look nice, aging materials effectively can sometimes be out of reach to many animators. In this entry level tutorial Dave Wilson demonstrates one way to make a can look like it has been kicked around and left for dead by the side of the road.

I get quite a few questions on texturing, so I've just take a simple Coke can and decided to show you how I textured it since most of my texturing follows these principles.

1. First I get my hands on some Coca-Cola label graphics.
Coke Can Label

Adobe Photoshop layers
Here's a photoshop look at the layers involved.
2. Then I go into Adobe Photoshop and stick this in one of my layers.

3. I then duplicate this layer, and keep the original untouched if I need it for some reason.

4. I then make my Base Metal texture; the texture that will be underneath the label/printing if it's worn away.

To create this sub-base texture you can use a photograph or textures from your texture library if you have one.

5. Place this Base Metal texture underneath (i.e. on the layer below the Coke Label layer in Photoshop).

Use the erase tool to generate a map that looks like this.6. I then use the Erase Tool set at 100% and begin to erase the Coke Label layer, revealing the Base Metal below. The result would be just like what would happen if you scratched away at the actual can.

So now we have something that looks like the Map "A".
