Here's a question I can't find the answer to:
Can I get alpha blending with glClearColor(...)?
GL11.glClearColor(0f, 0f, 0f, 0.5f);
This doesn't seem to do anything other than clear the screen to black. What I'd like to do is set up a fade effect, where rendered pixels slowly fade out due to the background clear.
Perhaps another way? A full-screen texture instead?
