Using Blender Render to export .bullet file

[ryanbartley]

I'm trying to export my blender render bullet world to a .bullet file. Unfortunately, all I've been able to find about exporting the .bullet file from blender says that you should do it through the game engine. It seems like when I bring my bullet world to the game engine it drops the bullet info. Is there a way to export the .bullet file from blender render rather than having to create all of my physics inside the game engine? The reason I want to do this is because I want to model and attach them to physics for rag doll effects. Maybe, I'm not thinking about this correctly but if you know how to take it from the render engine I'd be very grateful!
