I've got an FBX file with "name" and "shop_materialpath" attribs. Assigning multiple materials using either attrib causes render preview stuck at "Generating Scene". Single material works, but then the material is assigned to the entire mesh regardless of the attrib.
As far as I recall it's an issue in 6.3.2.1 only, can't remember to have this issue earlier. I'm on Windows 11, 2xRTX 4090 (CPU same issue though). It's pretty time consuming to blast/split all groups, apply materials separately and then re-merge again.
Any help appreciated!
