View Full Version : OpenGL blending...

12-13-2000, 12:02 PM
Hi! I read in a tutorial that an alpha value of 1.0 will give you a totally non transparent polygon. But when i set it that high, all i get is a transparency that looks a bit higher than %50... Is there anyway to get it more opaque? My goal is not to get it fully solid, but close to it. Any help would be appreciated. Thanks!

It all depends on your blending mode.

If you are using glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA), it should look completely opaque.

If you are using a different blend function, that might explain why it isn't opaque.

Yeah... that's the reason it doesn't look all opaque. But when i do that mode, the polygons look all out of order. I suppose i have to turn off depth testing and render the polygons in order from farthest to closest?
