Ok. I just wanted to see if I could make a sky in Blender instead of using Tarragen (the program used in the tutorials) and I think these came out ok. These are both low-res, high-res skies (512 and 1024, respectively). You would use them by typing "sky sand" in the console.
I think this would look good in that Strike at Karkand (Hotel Extraction) map, but s8n would have to finish it first.
Just extract this into your "\paintball2" folder. This file has both low and high-res versions.

This one is just a High-Res version of pbsky3. (512 Targa file)
pbsky3-hr4.zip ~50 Kb
