thank you for the quick response. What I am asking now is somewhere in between.
Lets go with my original example: I have 5 objects, all are assigned the material “Grey”. Originally Rhino 7 would create 5 materials called “Grey” and assign each one to one of the objects. I asked if this would be fixed so all 5 objects would get the same material “Grey”. You quickly fixed this a few month ago and I am absolutely grateful. Please do not change this back
Now let us assume I have 5 objects again. 2 have the material “Grey1” assigned and 3 have the material “Grey2” assigned in the FBX file. For some reason “Grey1” and “Grey2” have identical material definitions (same color, reflection etc.) except for their names (this is due to the fact that Deltagen materials cannot be fully represented in FBX, so some material will turn out the same upon conversion). When I import them into Rhino, Rhino realizes that the materials are the same except for their names and assigns “Grey2” to all 5 objects, discarding the material called “Grey1”. What I would like to happen though is that 2 objects still have “Grey1” and 3 objects still have “Grey2”. I absolutely do not want duplicates.
This is what it looks like in Deltagen and how I would like it to be in Rhino:
To sum up:
Original Rhino 7 behaviour: 5 objects with same material → 5 materials
After the fix from several month ago: 5 objects with same material → 1 material
What I ask now: 5 objects with same material definition but two different material names → 2 materials
