I've been attempting to make a skybox. Though I'm fining it hard todo as I barly understand what they are.

I'm trying to learn, how to make one. How to apply textures (to set the sky), and anyother tips needed.

So if someone could instruct me how to do it, I would be really greatful.

Hey Shaggy, I had a real nightmare trying to work skyboxes out, the confusing thing is there are actually two types you can use, entity or shader, I've not used the entity type yet but the way I managed to figure out the shader was to make a box with a sky on to simplify the problem and make compiling the test versions very quick. Here is my skybox test pk3, it makes the whole issue more clear. Just read all the bits to work out hows it's done and substitute your own, sky and path names etc etc etc..
Hope this helps

Actually generating the skybox images is another kettle of sardines.
good luck (:

I used Terragen to create my skybox for 'angryred'. I used this tutorial, it included a script for making the 6 sides (although you really have to go beyond the tutorial to get what you want, experiment with it):

This person has some free skyboxes:

This is the code from my sky shader, which is actually just modified from harlequinsky which can be found in the Nexuiz shaders.

Code: Select all

textures/angryred/angryred_redsky
{
   qer_editorimage textures/angryred/angryred_redsky.tga
   surfaceparm sky
   surfaceparm noimpact
   surfaceparm nolightmap
   surfaceparm nomarks
   q3map_surfacelight 60
// note: Change the surfacelight value if you want more ambient light from the sky.
   q3map_sun 1 0.961913 0.094789 100 240 130
// note: Change the fourth value (100) if you want a brighter or dimmer sun
// q3map_sun <red> <green> <blue> <intensity> <degrees> <elevation>
   skyparms textures/angryred/env/angryred_redsky - -
}

It took me a few tries to get the sun degrees right for my shadows to work with my sun location.
