Can't seem to change shoulder width

[Derk]

Hi

 

I was trying to create a custom body with Bodyslide tool as well as 3ds Max. I made the upper body slightly smaller by making the shoulders and chest narrow. Even if the mesh in Bodyslide/3ds Max has very narrow shoulders, in game they seem unchanged, like with the vanilla body.

 

Is there anyway to make the shoulders narrow, or is there something I'm missing while editing the body?

 

Also, is there any way to change the size of the individual bones like you could in Skyrim using the skeleton.nif?
