I’m looking for some advice for adding a BSDF to Cycles. I’m thinking of adding a dedicated hair BSDF based on the paper at http://graphics.cs.williams.edu/jcgt/published/0001/01/01/paper.pdf
I’ve had success implementing a few shaders on my own toy raytracer, but every time I try to work on Blender/Cycles I immediately get a headache tearing my way through the code. What I’d like is some advice on where to begin on testing new shader code in Cycles. Would it be easiest to start by altering an existing BSDF?
