Depends how you want to blend them together.

You can do a simple modulate with standard Texture Environment settings. Or for a LERP use TextureEnvCombine4, or use Register Combiners if you wish. There is probably no speed difference between them. (Provided you dont use too many RC’s). I suppose it depends what else your code is doing. IF you’re already using RC’s do it in there.
