Haguenau - breaking walls

Today - finally, I found solution with multiple physic. Problem was - I used few different objects in one X file, for main collision. When I join it - problem is gone! Now, I close, as newer for finish with this project, just need finish with shadows generation. Yes, it's take a lot time for find right setup I know, but it just for waiting, I hope don't require do, any new changes there :)
