Sort of an unusual problem, but I'm needing to be able to swap out the skybox texture for a map. My plan is to make a fake skybox brush in the 3d skybox that I can enable and disable depending on the skybox i need. So I made the box. and when I applied the texture I ran into a problem, I was easily able to fit a texture onto the top, but then I couldn't fit a texture properly to the sides. You can see that the texture scale is 5.625 x 5.625, so there's no apparent reason why the texture is stretched weirdly. The top texture has the same scale and it's fine. The brushes are both 5760 x 5760. I tried making them smaller, but it made no difference. The scaling issue applies to all 4 sides, and not just this one. If this ends up being a hammer issue and it ends up being fine in-game I'll update here when I compile.
