Switch_UseCustomPaintMapDurabilityAlpha
This switch allows you to add an alpha channel to your custom paint map that will "protect" parts of your custom paint map when worn. For example if you want a very worn weapon skin but retain important aspects of your design you would use a durability alpha. White is default durability, darker areas will "protect" your parts more.
