Substance Materials Render Gray w/Prorender

Substance materials render gray (well, the one I tried at least) with Prorender on Mac. Should Substance materials work with Prorender in Rhino 7 Mac presently, if they work with Cycles? Thanks!

Cycles

I’ve logged a bug and will take a look as soon as possible.

Hi, I’m having the same problem in Windows 10, thanks!
