New weapons problem

[MatiSk8]

I have a problem.

 

When I'm replacing my weapon in 3ds max, I'm doing it like this: I open my model and import to them f.e silenced.dff. I pin my model to silenced.dff and delete its mesh. I mark the weapon and muzzle and save to silenced.dff. But when I load it to the game, then it won't show up.

 

I tried also to tick only weapon withoout muzzle, but then in the game I can't see this muzzle
