I'm trying to pull off simple alpha blending but I'm getting strange results.. glBlendFunc(GL_ONE, GL_ONE_MINUS_SRC_ALPHA); glColor4f(1.0f, 1.0f, 1.0f, m_fAlpha); If I decrement m_fAlpha, when it goes below 0.7'ish it stops fading and it looks almost as if it's doing some sort of additive blending. Anyone have any ideas?

You get additive blending because it is an additive blending function. If you want interpolation, you need to replace first blending factor with GL_SRC_ALPHA.
