[Papervision3D] Finally my mini game is done, thx for all!

Yes that is possible.  I was trying to point out the overlap issue in the 
same scene that can happen if it was the situation you were in. Glad you 
solved it for your case!

Note sure how katopz did it exactly for sure.  Maybe he could elaborate.
