Adapt Armor mesh to Body in 3ds Max

[Capitto]

I want to make an animation and to prevent cpliping problemes in-game i want to import the armor mesh to the animation (just to see that nothing wrong is happening)

 

I'm a totally noob with this program and i'm still learning. When I import the armor mesh (armorname_0.nif), it is not adapted to the body mesh (too big or too small). Scaling the armor doesn't seems to be the solution.

 

What can I do?

 

Thanks!
