I’ve got a scene with about 120 objects in it in one FBX file. When I import I want to be able to click on one object and generate lightmap UV’s only on that one object.
At the moment, changing either: swap UV’s, generate lightmap UV’s etc, affects everything in that FBX file, and so Unity appears to lock up trying to create the UV’s (I’m assuming it’s just taking a long time).
Is there a way to generate UV’s on a single object (and then keep the UV’s instead of having unity generate them at load time?).
It seems like the best thing to do would be to break up the scene. Save out your objects as separate meshes and put the scene together in Unity. If you had a room with a bunch of columns save out one column then place it around in unity because unity will instance the column and it will be much more efficient and you will have much more of that control you are looking for. Of course if its a huge truck with a bunch of different parts this does not work so well.
