Quote - You can do all that and more from Python. I have written support for 3Delight and a basic Yafray plugin (feel free to work on it, it's GPL licensed) and other people have created things like PoserPhysics, Wardrobe Wizard or GlowWorm.

stewer you're right and especially Wardrobe Wizard is an excellent collection of Python scripts. But have a look, how smooth xfrog is integrated in Cinema 4D and watch the plugins for Carrara. Much better integration and higher flexibility!
