Good point, Erlik. I'm merely striving for perfectionism, here... It's all up in the air, anyway. Maya doesn't export objects without some kind of plug-in, which I don't have. So I'll just stick to the Rhino-to-Bryce solution... I'm not quite ready to do the whole scene in Maya, although that might be cool... I don't know how to use Poser characters in Maya, at all... Also, to do a chain the length that I need in Maya, with this rigid body /gravity technique, would drive any PC to it's knees, and take as long to calculate as the scene probably will to render. I tried the calculation on 12 links and had to close down Maya after waiting half an hour with no response. I must not be doing it right!
