Well the 3D scene is pre-rendered with a special technique (special texture and separate lighting etc) from 3ds max.. and then Im adding realtime texture onto it.. and freeframe before that on the texture - and freeframe after the 3d is "rendered" and voila

- so - 3D = prerendered in special format, texture is live and freeframe before and after is live.. at 30fps in 640x480.. depending ofcourse on the speed of the freeframe fx..
Its all in c++ yes.. but the 3D object is "prerendered" - Ive made my own packed fileformat for this.
I am thinking to make some freeframe fx based on this tech in the future, theres a lot I can do with it
