Only thing you can do is use applications like carrerabryce, or vue that easily can import poser content. Vue's renderer though is probably the best of those three.

PoserPro supports collada format, so once it's released, you could use any application that supports collada import, like Lightwave, Max, XSI ect, but then yer also talking a LOT more dollars as well for those.

For the really BETTER renderers you are gonna have to end up shelling out some serious money for them.

Way too many people take way too many things way too seriously.
