Smallworld, I'de recommend looking into the info in whkguamusa's post. Since I don't use Rhino I'm not sure how files act when imported for it. I do know that Pose DOES NOT like triangles. I hesitate to ask but if you want to send a small sample mesh to me I'd be willing to see what I can find out. However it seems whkguamusa knows both programs and has some good ideas. PErhaps your detriangulationg but then using Carrara's "smoothing" command, which pushes the poly count right back up? mike
