No, ScottA, it's worse. His T-Rex is 13.8 meg (the .obj file, anyway). The numbers above represent the number of polygons in each figure's mesh, not the filesize.

On my current system, Poser 4 slows to a crawl when I load it. Your own Rex is far more resource-friendly, but I've kept both for variety.

And just to demonstrate how mad I am, my second Poser animation experiment used Questor's Terminator, which is even rougher on my system than George's T-Rex.

I expect that Stephanie and the Millennium Girls/Boys have polycounts similar to Michael and Vicky, respectively, since they're derived from those meshes.
