Additive blending is usually done with: glBlendFunc(GL_ALPHA, GL_ONE). (GL_ONE, GL_ONE will act as though renderamt is always set to 255.) If you want to use non-additive blending (like rendermode Texture), it'll be: glBlendFunc(GL_ALPHA, GL_ONE_MINUS_ALPHA). Can't really comment on the palette generation question. -- Laurie Cheers _______________________________________________ To unsubscribe, edit your list preferences, or view the list archives, please visit: http://list.valvesoftware.com/mailman/listinfo/hlcoders
