I think the 3ds object has to be mapped in the software where it was created. Then it imports fine in Vue. But there is another way, maybe. If your 3ds object is in only 1 piece, you can try to split it first and to map it in Vue piece by piece. That's a little my 2 cents, because I have no software that can export 3ds files. Somebody else can explain it better for sure. Guitta
