skybox problem

[==Troy==]

I have done a proper skybox, inserted a skyportal in it, wrote a shader for it (actually copied it), (It is a stratisphere skybox). But I dont know what texture to use on the walls of the actual map (and not skybox). Do I leave them caulked, or some specific texture? I have read guides, but thye dont say what exact texture I need to use :( Thank you for the help!.

Use any functional sky texture - I usually use the goldrush sky.

Make sure that you perform a full vis, using "vis -fast" can give you the HOM effect.

there is some REALLY NICE sky in Praetoria map :)
I love that map :)

Do you have to have a light inside the skybox? Because everything I am getting is just black walls.

[MrLego]

Are there any lights in your map?

The skybox shader should emit some light but because it is a night sky you may need to brighten the map up a bit.

You could always put "_minlight" "15" in your worldspawn entity until you get things lit up properly.

I dont have any outside light at all. The only light is from the sky entity.

Is it possible to have a full brightness texture without the light? Do I need to do in the shader, or put light into the skybox, or actually light the walls of the map? Thank you for your help! :)


Oh, light in the skybox worked, thank you!. The very-last question, how to mirror a texture? Not rotate by 180, but mirror it :(

Ok, I have done a good, working skybox, thank you for all your help!.


And just wondering, is it possible to use movers in the skybox? Because I have tried a func_rotating with origin and spawnflags 1, and it just didnt appear in the map..:|

[MrLego]

I have seen skyboxes used with animated shaders (blinking lights on a tower), never one with something physically moving in the sky portal cube.

Why, you want to create a moving sun? ;)

My suggestion for that is to create a sphere al around the map.
So there is kind of a platform in the sphere, and let the sphere turn, keeping the map itself horizontal

I know, from the lot of experiments that I did yesterday I found this :

1) It is not possible to use mover in the skybox. It will not just be transferred as a sky part
2) It is theoretically possible to change the angle of the skyportal, but the script for that will not provide a smooth rotating and will delay all other scripts.


So, generally speaking, skybox is only for static skybox, therefore if you want a moving sky, use a mover in the map with a shader, which will provide an effect of the sky light.

And i is not nessesary to make it a sphere, just a cube is enough.


And I need a rotating sky for interactive gameplay, because I have a space-ctf map, with a lot of space visible, so moving skybox will give an impression of the buildings themselves rotating in the space...
