I don't have the color correction node in, I am in the middle of a project right now. I think because there was no roughness data to pass on. My fault. The Datasmith actor thing is true, too.
1. Probably because I looked at the parent material and the model was on a SPEC work flow so Roughness wasn't even piped in
2. It was and Datasmith Actor selected and that causes the same thing.
Soo much fun, but if you need anything from me, I can do videos instead of post also
