So I’m working on a set of assets, where some of which are things like windows, and they consider of the outer frame, the inner frame window part and the lower window part. The lower window part is a separate mesh, as it should be mobile, so it can open up and down. The outerframe and inner frame window part is currently as separate meshes, as currently I have a couple of different frames, and I might have some different inner frames.
However the question is, should I have it as separate meshes, or should I make sets? Is there a problem with having it split up in too many parts? And what is the best way to do it, do you export the frame separate as FBX and the inner frame and lower part in another FBX?
Because since I want to try and keep all the frame textures on their own texture sheet, I would need to use two material IDs if I combine it I think, right?
EDIT: Updating the post to have an example image of what I mean. The first is the full window, and the next three are the parts that it consist of (there is actually a 4th I forgot about, the part below, but never mind that).
