So whenever I make a copy (duplicate) of a material instance, it loses its link with the original parent (master material)
- make a material instance. (of existing material)
- Move it to a subfolder.
- open mat instance.
- add a preview mesh to it.
- copy the material instance (not an instance of the instance)
- open the copied material instance.
- Profit… (as in, bug)
number 2 and 5 are optional, but seem to result in always causing the bug.
Innitially it will look like everything is fine, but when opening the duplicate material instance for some reason the parent linking is gone.
It still “says” that the parent is correct, but you will need to manually update it for the duplicated mat-inst to work.
