Set Texture Alpha
Hi,
How can I set the alpha value of a texture without setting each
pixel's alpha? Any OpenGL functions can do that? Thank you

Textures are combined with the underlying
polygon. Set alpha in the polygon.

Another option would be to use another texture just for alpha channel (and
use one of the multitexturing functions which I'm still trying to figure
out). You can neatly combine both (texture and alpha) in a single TGA file
for instance.
