In Rhino 5 (and before) we used to be able to make a duplicate of a material assigned to layer via Layer Material dialog:
What happened to this in V6? How would I quickly make a material copy while editing Layer Materials?
Hope I am just missing something obvious.
EDIT: the “make unique” dialog shows for PerObject material on Materials/ObjectProperties panel. But not for Layer materials that are duplicated…
EDIT2: the reason why the option to “duplicate” the same material stems from the bug below. When copying layers or matching layer properties, sometimes, even though the material is the same, the duplicate is not detected.
