Brent LeBlanc Shows How You Can Add Variation in Materials Procedurally Using Object ID.

Have you ever wanted to randomize a texture that is shared by multiple objects automatically? Developing procedural solutions like that can help save some time while also adding some natural variation to your work.

Brent LeBlanc is a Texture/Shading Artist for Film/Animation and demonstrates how you can quickly set up a switch node that is driven by Object ID. When you duplicate an object, it will receive a new Object ID and in turn, receive a new variation of the texture.

LeBlanc Uses Arnold in Autodesk Maya, working with the ai Utility node, ai Random Node, and an ai Range node. With a few simple connections, they can all come together into an ai Switch Node.

LeBlanc accredits Mads Draschler, who helped with the setup.
