I think (don't have it) That the program with the most support for Poser (out of the box) is Vue. and it's pretty cheap. If you want to do animations you can get Mover (4?) and have some real cool integration and some very neatoi built in features like camera shake. Also Vue with Mover supports network rendering if you have more than one comp. I've been tempted a few times I must say. Oh and from everything I've heard Bryce is a stone cold pain inm the butt to use with poser... but again that is hearsay.
