Menu is opened when pressing F7 by default.

A mod that allows you to set your viewmodel stance the way you like it!
Usage:

• After installing the mod enter a heist with the weapon you wish to tweak.
  
• Open the menu using F7(Can be changed in base.lua)
  
• Start playing with the values and see what fits you.
  

Some notes: 

• You can slide the number boxes by holding right mouse button and moving.
  
• You can press some buttons to set the current stance.
  
• There's an option to apply viewmodel on all weapons, this might give you weird results sometimes.
  
• If you make custom weapons the stance values are inside mods/saves/PerfectViewModel_Options.txt, you can also use the copy XML button.
  

*If game crashes or the mod just doesn't work, please make sure you have the latest version of BeardLib(3.03+)
