Are there some functions to do some collision detections in blender or use some stuff from the game engine in the “normal” blender so that I can do some simulation stuff and then render it out?
there is a script to save animations from the game engine
however, the game engine cannot have deforming bounds on anything, and in general has a lot of problems if you want a lot of detail.
the script is game2ipo or something [game to ipo… I don’t know]
game2ipo, you can find the addresses here:

Bloded does collision and pysics simulation.
