Updating to make it fully validated with pbr

Reduced maps to 2k, can easily supply 4k maps if neccesary.

Updated normal and roughness to account for changes in gunsmith shader

Fixed values on albedo

Updated with all neccesary maps to adhere to new PBR system.

Updated to validate with PBR, if there are any issues please let me know I can almost certainly resolve them rapidly.

Created USP-S | High Octane (Cotton Candy).
