Hello, I have two building variants that are essentially carbon in a different color. When I build them for the first time or upgrade them from a material that isn't carbon, it works perfectly.

If I convert to a different material first and then select the desired one, it works again.

However, when I try to upgrade them from one of the three carbon variants to a different one, they look exactly like carbon, but all other values ​​are changed as desired.


I'm a bit confused, I've already tried creating new materials, but that hasn't worked so far.

Does anyone have any ideas?
