How to implement a standard cubemapped skybox?

Thanks for the info. Will give your changes a shot when I get home Daedalus!

I’m more curious why this hasn’t come up before. How is everyone else doing skyboxes? Surely I am not the first to try the suggested method of “cubemap as skybox.”

I totally understand why these are capped to 512x512 if you assume they are only used for reflections and lighting.
