I’m trying to keep track of certain faces, after I separate some of the faces into a new object. Apparently, the new faces are created, so neither index, nor reference to the face before the separation are no longer valid. Is there any way to find a new face in the separated object?
So far I’ve managed to do it with BMesh layer. I’ve added faces index in old object as custom int layer to the faces before separating, apparently the BMesh layers are copied over when objects are separated. But There should be a more elegant way to do this probably.
