Need Quake2 style skyboxes

Recommended Posts

tcs    122
Hi ! I coded a Quake 2 Skybox class. Now I need some good textures for it. Can anyone point me to a place where I can download some ? Or even better, can anyone do some for me ? I think you could do them with Bryce or Terragen. Thanx Tim Tim -------------------------- glvelocity.gamedev.net www.gamedev.net/hosted/glvelocity

Hi!
Sorry no answer....but a question:Can you give me a little hint how the skybox stuff in q2\q3 woprks?
I mean in my Q3-Viewer shaders work perfectly and the sky looks perfect texture-wise.
But the geometry looks completely wrong if I just render the faces referenced in the bsp.
Somebody told me that in Q3 the geometry for the sky is created at runtime out of the referenced faces in a special way.Do you know how this is handeled in Q2?

P.s.:Why don´t you take the sky-textures out of Q3´s *.pak file?They look good....Especially the kill-sky(Q3DM1).

Greets, XBTC!

Don''t want to rip something, I would rather like to know how to do my own with Bryce...

Can''t say much about Q3, but I''ll upload a Q2 Skybox class on my site later this day, take a look !

It''s easy, really. Create your scene as usual, and place a free camera in the middle of it. Now you just need to render your six skybox sides with a 90 degree FOV. You can do this by pointing the camera along each of the primary axes (X, Y and Z, and in both directions of course), and then rendering a square bitmap (I use 256x256).

Very important: there''s a bug in Bryce that results in incorrect FOVs. If you want your FOV to be x degrees, you should enter x*1.25 in the camera dialog. In other words, you need to use a 112.5 degree FOV (90 * 1.25).

Also important: the "Link to view" toggles in your sky options should be OFF!

Thanx guys, I and my friend made some skyboxes. Had something to do with the FOV scaling must be set to 72 or so, if I remember it right.

I''m amazed that skyboxes are really just boxes, cubic environment mapping and such stuff is really simple ;-)

Anyone know where I can get a demo of Bryce?
