I have multiple 3d scenes that worked very well as recently as Create version 2021.3.8 - my only issue is some bugged texture reference paths (I can easily resolve these by hand).
Upon updating to 2022.1.2 many of my textured materials have turned to red with the console citing all different kinds of texture reference issues and mdl generation issues.
I’ve isolated your bug down to a single material that I can reproduce in 2022.1.3 and 2021.3.8. Will get back to you when we understand what is happening.
