Hi, I agree about problems, due to the usage of RAM! (once got similar problems with huge scenes of 50..60MB+, until I did upgrade to 256MB. And imported(?) "cords" can be memory-consuming. I once tried to export a desk-lamp as mesh from RayDream4.2 that had a spiral cord and that program did create that cord from zillions of triangles. The more the curving, the finer the mesh. Well, that lamp itself then was only 200kB, but with the cord, I got >20MB, if I remember right!! Ouch! ;-)
