How to make color keying in OpenGL ???
Author
Hi. I want to make mask. But not with multitexture or with blending mask. I want to do it like in Quake, HL, Medal of Honor. With a coloy key. Take a look on the trees in Medal of Honor. I want to do similar.
Thx for your help
OpenGL does not support colorkey, you have either to use blending, or alpha test, or both. In all cases you need an alpha channel with transparency information.

I haven''t seen the trees in MOHAA, so I''m not sure what effect you''re going for. I don''t know why you can''t use blending, though. Put your tree image on a black background, and do blending like glBlendFunc(GL_SRC_ALPHA, GL_ONE).

Ok, I think I have a better understanding. But I believe you''re still going to have to do alpha blending, with an alpha channel specified in your image.
