Is there a way to change which .mat an .eff uses without changing other relating effects? I would like to make one .eff that's based on the "WhiteSmoke" .mat into one which uses the "SmallDirt" .mat, but I don't want to change every other .effs that's based on the same "WhiteSmoke" .mat. So far I've just renamed .tga files to do this, but that won't work this time without changing a lot of other effects. Is this possible to do? Thanks.
