Animation Master with the export plugin from Obsidian games. It has a very sophisticated animation system (only compareable to maya), is a very cool low poly modeller and very cool texturing functions. And the Obsidian exporter can export animations.
I am working with that programm, but i have used it oly for exporting segment meshes (not animated) so far. Up to that point, it works fine. At the moment the workflow for my project is in the stage of doing the enviroment and scenery stuff (segment). after that the animated stuf (new characters and entitys are on my schedule. I will keep you updated how it works.
By the way, i would recomend Animation Master also, because it is quite cheap (just about 250 €) and therefore, it is a good way, to get all your developement standing on a legal base
