What exactly you mean by "anims just break"? Because I had a problem that animation from decompiled V model turns left after compile (I mean, if you compile model once again, but you didnt touch anything in _anims folder), but It can be solved by re-compiling all of those initial animations once again.

Is there any way to make derbis from breakable prop physical? I mean, it suppouse to collide with player and etc..
