I'm not familiar with C4D or Amapi but the top image is part of an animation that has somewhere in the neighborhood of 50 million polygons. I'm not great at 3D studio but I'm pretty sure that if I tried to make a model that size in 3DS it would crater discreet logic and we'd never hear from them again. In my experience Vue is the best at this sort of thing. In fact I don't think 3DS can even import or export a model over 65,000 polys and if you try to export a 3DS file over that size in Vue you will get an error. I'm sure I'll figure it out and I'll let you know how it goes. Bot
