OK, so I'm diving into Karma and materialX
Have a project where apparently principled shader's SSS fails but MaterialX SSS shines. However I need to drive a mix node based on a point attribute I created based on curvature. Does anybody know how to access point attributes in MaterialX?
Also, I think Karma has no dispersion implemented at all (apparently neither Principled nor the MaterialX work). Or I just fail to notice few things.
Thanks for the answers, replies, etc. in advance!
Karma, MaterialX, oh my

Check out the USDPrimVarReader. Just be aware that some common attributes get automatically converted (Cd for example) and are called differently.
As for dispersion: I'm not 100% up to speed, but I think it's still on the "to be implemented" list and not available now.
