Made changes once again to make sure it validates with the pbr system!

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

Updated normal and roughness to account for changes in gunsmith shader

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.
