Made a new model and animation. In 3D Max it is displayed normally, but after export some of the bones stop moving or do not move completely.
Can you help?

Hello, I have a problem with unpacking the map. When I decompiled the map, the information about the zones that the player cannot enter (the "Passable" brush on the level editor panel) is not imported.
Screen #1
P.S. I applied this zone myself, it was not in the decompiled map

For example, in the original, it is not possible to go into the river. After decompiled a level with river, do a Rebuld patch and compile the map, I can freely move into these zones.
Screen: #2, #3

Can you say something about this situation?

P.S.2. Sory for my bad English.
