Quote - Anti-gamma incoming material. Add together diffuse and specular.

Gamma correct the result.

Anti-gamma is Pow with Value_2 = 1/gamma , i.e. usually .454545

Gamma is Pow with Value_2 = gamma, i.e. usually 2.2

Color_Math must be used.

There's a Wacro posted somewhere that sets this up for you on simple shaders. More complex ones could be automated but would be a lot of work.

This discussion will point you there.
