Having a weird issue with a gun I uploaded that uses PBR materials.
as you can see in the short clip, if I make any sort of change to the object, some of the PBR materials become unlinked, and revert back to their default white. To fix this i have to go into edit and reassign the corresponding PBR material to the broken links. This is the first time I've encountered this and some help would be greatly appreciated. Also note that it is not just the edit I made in the video that causes this but ANY sort of edit apparently, including simply resizing the object causes the same issue to occur.
