Lee Griggs demonstrates working with the new Arnold Distance Shader to mix paint where objects intersect.
The latest iteration for Arnold Render added a new Distance Shader. The shader uses the sample rays to estimate the distance from the shading point to the nearest surface.
If you want to use the Distance Shader in practice, watch Autodesk’s Arnold Rendering Specialist Lee Griggs create a paint mix effect using the shader.
Griggs shows how to use the distance shader to simulate the effect of two colored paints mixing.
Also, check out this tutorial that shows how to create abstract works using the Distance Shader and the Clip Geo shader in Arnold.
