View Full Version : Bizarre alpha problem.

Hi, I have got alpha working in my textures under win98 and 2000 using GL_RGBA8 (although 98 will work with GL_RGBA).

But when I try to get the same program running under NT using both of these internal formats, the texture is invisible.

Is there a way of testing what the best internal format is for a specific driver?

That sounds like a bug. All formats should at least work; your choice of a particular format (RGBA4, RGBA8, whatever) is more an indication of the degree to which you value performance and small texture size vs. visual quality.
