I'd love to post the video from Poser and the video from Carrara, but when I try to render the video in Carrara it keeps showing memory allocation errors to stop the process.

I also can get Hiro and some shorts on him in Carrara, but when I try to bring in a shirt it isn't conforming to him.

I've tried making this video from Carrara for about an hour, but the memory allocation errors (I have 8GB) have me stumped.

I want to show how in Poser his neck bends (he looks down) and arms lift, but the same BVH in carrara leaves his head and neck looking up and his arms don't bend correctly.

Carrara looks to be a lot of trouble.
