Your probably right Quintus a separate download sounds like the best route. Personally I've stopped using the shaders i prefer to see the lighting and fog effects more.
I'm putting my time off to use so I've started working on something for the Luftwaffe field division helmets. Here is one of the Luftwaffe decal helmets and a plain.
Even though i don't have Fortress Italy and Gustav Line yet I'm toying around with some tropical helmets for those who do have it.
