Oh and on a second note, I thiiiiiink that substance uses GLSL as the language for it’s shaders and that the vray for maya install includes a copy of the vray material in glsl?
We’ve had some discussions with Allegorithmic, but things didn’t get anywhere. There is no public SDK for Substance Painter/Designer, so there isn’t much that we can do on our end. I would suggest that you contact them as well. Compare that to Epic, who were extremely helpful and supportive.
It does indeed use GLSL. I’ve looked for the vray glsl file (trial version for both maya and vray though, not sure if that makes any difference) and couldn’t find it. Any pointers as to how I could find it give it a try in Substance?
