Here's my first contribution, a desert sky for the Egyptian hub: Download

I made this awhile back while testing Newhexen's skybox feature, but I don't think I will be using it for Ravenhurst.

Unfortunately, UQE doesn't let you install default skyboxes for each hub (yet, hopefully this will change) so if you want to use this you must add the following to the worldspawn in each level you want it to show up in: (Quark works good for this)

"sky" "desert" 

So it ends up looking something like this;

{
"worldtype" "0"
"message" "410"
"wad" "D:\Hexen2\Textures\RT.wad"
"classname" "worldspawn"
"sky" "desert"
}

Of course, make sure you place the unzipped files into a 'skies' directory in the data1 folder for normal hexen, or the 'portals' folder if you have the mission pack.

You should update your engine with the current one on the website and see if that fixes things for you.

Then, after updating, post another screenshot of your map so I can see if your results are improved. Nice map by the way!

I doubt that its a skybox size issue, since the engine can load 512x512 sized skyboxes, and if Im not mistaking it can also load 1024x1024 skyboxes.

One thing it could be is that your level might be clipped because of the z-buffer.

Try using the command "gl_skytype 0".. this will render the original sky.. if your level is still clipped, then its the zbuffer depth and not specifically the skybox.. this is since in the update (when did you download it?) the sky gets rendered to the screen buffer without depth information to the screen, then the rest of the level just renders over it.

Best would be to send me the BSP and the skybox and I'll test it and see how the results comes out.

If possible, zip the GLHexen2.exe file you are using with.

Try updating your engine, it should make all the difference.
