What's the matter with you?
I haven't seen a single upload of yours ever work.
The left texture should be called _lf not _lt ...
and again : they're not named correctly, the sides don't fit this way.
this skybox doesn't work

Most of the uploads I put up do work, but people delete them and repackage them. Or they just remove them completely. Such is life. My skyboxes don't work out of the box -- they are 2048x2048 textures and need to be resized. I give you the entire skybox at 2048x2048 so you can use your favorite imaging program to resize them, or change the engine source code to support higher resolutions for texture maps.

how do you change your sky's wen your makin a map?

long ago, but your comments are always...up yours
We are humans, not your stress doll.
It's true, herb should fix this thing, and test it himself...anyway, keep making em, and make em work :D

<><><>Pretty simple. Get tons of sarcasm here. Then, consider about the sarcasm, use one of it and make better maps. Thats how it is. Theres certainly better mappers than me because they spend more time on their maps.
