Moving clouds ?

Recommended Posts

Hi, I''ve got a question about SkyBoxes: "How can I realize moving clouds like in UnrealTournament ?" At the moment I use a second SkyBox that is translucent and rotated about the Y-Axis. This approach looks okay at the horizon but crappy when you look straight up. So how do games like UT do this ? Any ideas ? Thanks, VK

Well actually it''s as easy as changing the texture coordinates... I don''t know how UT does it but that''s the easiest way to make ''em clouds moving...

That''s exactly how UT does it. It renders the clouds as a REALLY BIG polygon above, and simply increments the cloud texture''s u and v texturing coordinates by a predetermined amount (built into the map file).
