Clay

A procedural clay shader made in Unity 3D's ShaderGraph.

How does it work?

• Textured fingerprints leave dents in the normal and add smoothness to mock natural oils from skin.
• Voronoi noise is used to flatten normals, creating a handcrafted look.
• Perlin noise is modified to form valleys, dimming ambient occlusion and subtracting normals to create a folded appearance. (Doesn't look very good as yet).
• Tileable Perlin noise is used to displace mesh vertices at normals to the surface, providing a seamless bumpy look.
• Small heptagonal impurities are randomly generated on the surface. (Doesn't look very good as yet, and performs very poorly).

Installation

Open the project in Unity. Open the Purveyor of Stars scene located at clay/Assets/Scenes/.

Warning

I created this procedural clay shader as an exercise in Unity 3D's ShaderGraph.
Shaders are run every frame, and since this is an unbaked shader, it generates and then discards various noise textures each frame.
I would therefore strongly advise against using this shader in it's current state in commercial usage.
Instead, one could re-create the shader in Blender and bake it into materials and animations.
You would then benefit from peak performance, with results that you can be just as happy with!
