Physics not simulating in final render...

Well…I set up a little building with some stuff, It works in preview(or whatever aka pressing p), But when i render, All the objects don’t move at all.
A 1 hour google seach found nothing, any ideas? Anything i can do to help?
Thanks

P key is for starting the game engine. If you want the simulation to work in the actual render (the ANIM button), you need to bake the game engine keyframes. Find and select from the upper menu “Game -> Record Game Physics to IPO”, then run the game engine from P key. After you exit the game engine (ESC) the objects should be keyframed the same way than in the game engine simulation.

Oh thanks! That explains why it worked before and not now XD
