Viewmodel inside-out

[Nocrex]

I made a viewmodel for Garry´s Mod and when i loaded it up it looked like the handle was Rendered inside-out. Also the wrist of the model is twisting when I look around. I am using Blender 2.78, Crowbar 0.42 and the c_models from the wiki page.

Load model to Blender, switch to Edit Mode and use "Switch Direction".

Thank you, that worked. But I still have the problem with the twisting wrists.
EDIT: Fixed it myself. I just had to remove $proceduralbones from the qc
