Using Primvars For Proceduralism

Here are some renders using primvars to vary a few of the attributes on a shader to create a range of textures, using only 1 shader.  This is through using python scripts to create attributes on the objects following a certain naming convention to connect the attribute values to the shader values

Without Primvars - Same frequnecy and colors

 With Primvars - Varied Pattern Frequency and color variation

I Will make a quick tool to make creating these primvars a bit easier that running separate scripts
