Hello, I'm making a Silencer weapon. I have finished my modeling and I need to attach it to the correct bone.

Using Blender, I take these steps:

Import Silencer body
Select my model then the bones
ctrl+P -> With Empty Groups
Then just select my model
Go to edit mode
Go to object data tab
Scroll down and click "RWeapon_2" then the assign button.

After that I just export. When I try to submit it, it attaches to the wrong hand, it attaches to the shield hand and it moves like a shield (if silencer plays the death animation, my weapon rolls away).

What am I doing wrong?
