texenv with a single color component?
Author
I have a bunch of large grayscale textures so I figured I might as well store four of them at a time in a single texture, but I can''t find anything that will let me take out a single color component with the same method as the GL_ARB_texture_env_combine extension. Isn''t there anything I can use?
If you dont use pixel shaders i dont think you can. Maybe with glColorMask.

You''ll need NV Register Combiners / ATI Texture Shders for this. Or at least ARB dot3.
