Cheers! I need to tweak it and test it how it works for animation / moving camera. And I just noticed that I forgot to add pure white for "specular highlights"
Now it looks a bit dull.. Also what I have in mind is making the actual use of the shader faster, so that I can just choose one color, lets say blue, and the current grey scale shading just adjusts it for light/shade. Havent really thought how to do that though. I'll share when it's done (and if it's never done I'll share it anyway
)
