    seperate glTexCoords for alpha channel?

    The alpha channel is a radial gradiant which would be mapped to a quad. Now I'd like to be able to specify independant glTexCoords for the RGB channels so that I could slide/scale them.

    Maybe that isn't how the effect is achieved but it seems like a good description.

    Im not sure exactly what you need, but have you considered multitexturing?
