Hi, Mathematica must keep all the frames of you animation in memory and this is probably to much. You can make simple animations with MathGL3d http://phong.informatik.uni-leipzig.de/~kuska/mathgl3dv3/ as explained in the MVManual.nb. But it depend a bit on the complexity of your scene and the actual speeed of MathLink. Regards Jens "Steven T.
