I should stop doing that now.
Anyway, I've gone to this site called the WadFather where they have loads of textures, and loads of skyboxes. I downloaded a zip with a skybox in, then I imported it into GTKRadiant, the way that isn't in any tutorial i've seen, and it showed me all the TGAs and JPGs but there was no red checkered one that looked like the joined together skybox.
What I'm asking is how do I turn all those JPGs and TGAs into the skybox I want in my level.

I bet Llawnroc will be the first to answer this, cause he's being very helpful at the moment.
So's Tee for that matter.
Anyway...

And what else is nice?
Umm...... Singleplayer levels...

Seeing you mentioned it I will answer 1st but......there had to be a but!!!!

I don't know!!!!!!! I'm still new at this myself and I don't know!!

Sorry!!!

(Llawnroc wanders of to a dark corner and repeatidly bangs his against the wall for not knowing somethin!!!)

The red checkered boxes are the shaders themselves!
They are a piece of code that the game understands and when compiling, it puts the images of the skybox in the correct positions in a complete skybox (6 faces). The shader code includes the filenames of the JPGs to use, therefore, if you download a skybox, you need to MAKE a shader telling the game to use the new JPGs, then, if the shader works correctly, you can use your new skybox...

All I can say is that. I do not know how to code shaders or EXACTLY how to work with shaders but there are some people around here who do know. I suggest getting a shader from another skybox, and modifying the code as is to include your new JPGs for your new skybox, then simply saving it as another shader name (to not replace the old one) and you should be able to use it...
Now, where you put the shader?
I don't know...
Where you get the shaders?
I don't know...
etc...

You do in fact have to modify a shader. However, its not that tough! Here are the things I've figured out.

1. Open skies.shader in Notepad.

2. Copy a section eg.

textures/skies/yavin
{
qer_editorimage textures/skies/sky.tga
surfaceparm sky
surfaceparm noimpact
surfaceparm nomarks
surfaceparm metalsteps
notc
q3map_nolightmap
skyParms textures/skies/yavin 512 -
}

Paste this in somewhere in the middle.
Now, I'm not entirely sure what everything does here but if you change everywhere where it says "Yavin" to your new name for your skybox eg. "Coruscant" the textures can then be put in the textures/skies folder with the names coruscant_rt.jpg, coruscant_lf.jpg etc. I haven't tried this yet but I'm off to try it out now.....

Hope this helped.

That will work fine. But to clear up a bit of an error;

The compiler will NOT add six faces and put the textures on them. The GAME will add SEVERAL HUNDRED.

Holy moly. Ok...
I find the skies shader. Copy it and rename it, then open it and change everything to corespond with my jpegs and stuff?
Or do i, open the skies shader. When inside it copy a part and paste it again at the end except with everything coresponding to my jpegs and stuff?
I'll try it. I wish there was some program that would do this for me.
I'm gonna look round the quake3 sites and see if there is.
If tell you all if I find one.

You in fact have to edit the skies.shader that already exists in the game, adding your bit at the end.
And I can tell you a program that will do it for you - the one that actually comes with the JK2 tools. Not quite sure how to work it but have a play.

Actually, no, you DON'T want to be editing the ACTUAL game shaders, I can tell you that RIGHT NOW...what you want to do INSTEAD is COPY it, look at it and save it as your own for your pak.
here's some more info.
