The bake looks ok, but once I try to add the silk the viewport becomes unusably dark. I retraced the relevant steps back into Chapter 4. Checked the normals, shared origins, naming conventions, re-exported the files, recreated Instant projects and rebaked several times. I've also patterned matched what is on Chunck's screen and what is on mine. I cannot spot a difference.
I have put real hours into trying to solve the issue. As InstaMat is a new program to me (and probably most people viewing this course), getting stuck here is a total momentum killer.
