Apropos Terragen:

there are a few tutorials on Youtube about Terragen itself.

Anyway, when you make your scenery and you're happy with it, use the following to render your sides:

Camera global settings for skybox:
Camera settings -> Zoom -> 1,0 [this makes it a perfect 90° camera]
Image size -> 512x512 [you might use 256x256 if the quality is unimportant to you]

Camera orientation -> 0 0 0
Render image -> save -> xxx_rt.bmp

Camera orientation -> 90 0 0
Render image -> save -> xxx_ft.bmp

Camera orientation -> 180 0 0
Render image -> save -> xxx_lf.bmp

Camera orientation -> 270 0 0
Render image -> save -> xxx_bk.bmp

Camera orientation -> 0 90 0
Render image -> save -> xxx_up.bmp

Camera orientation -> 0 -90 0
Render image -> save -> xxx_dn.bmp

Convert them into .jpg and put into env/yourskybox.

As for the shader:
Code:
textures/mymap/skybox
{
        q3map_lightimage textures/mymap/skybox.jpg
        qer_editorimage textures/mymap/skybox.jpg
        surfaceparm noimpact
        surfaceparm nolightmap
        surfaceparm sky
        q3map_sun 1 0.98 0.4 70 0 90
        q3map_lightsubdivide 256
        q3map_surfacelight 330
        q3map_backsplash 0 0
        skyparms env/yourskybox/xxx - -
}

Adjust surfacelight and/or sun to your needs.

textures/mymap/skybox.jpg is the editor-only image for the skybox (just so you know that you put the right one, you can basically use anything for it as it doesn't appear in-game)
