OSL Ambient Occlusion Shader: Procedural Dirt

Today we’ll explore yet another way of making procedural dirt (ambient occlusion) in Blender, using OSL shader by Francois Gastaldo.

Note that I’m using modified version of this shader, posted by BAO2 on Blenderartists.

Original version at Francois blog.

    Excellent! I will certainly give Bao2 a shoutout for this one. Thanks for bringing this to my attention Gleb! I was really fighting the dirty vertex paint, and this works so much better, especially with the “Inverse Effect” for models with a crazy amount of different edges.
