i''ve been wondering about how the programmers of Half-Life/QuakeIII/UT etc have created the sky.. is it just a spheremapped surface, or what? i simply cant understand anything (yes im so stupid). mvh Rasmus Neckelmand ---------------------- Rasmus Neckelmann

The easiest way is to use a skybox, just make a big box with a sky texture. Then you render it before everything else with the zbuffer turned off, and you set the view matrix translation part to 0;0;0.
Of course a hemisphere looks better...

Hi,
or you could use a skybox and emulate a hemisphere, so you don''t need that many polys for it. IIRC Quake does it this way.
