Skybox Error, I am in need of assistance....

The skybox should also have the toolsskybox texture for one, and 2: is your sky_camera aligned with the map origin (0 0 0)?

Here is a great tutorial on how to do skyboxes the right way.

Finally, I guess this is more for mods, can we have this moved to the general questions and discussion section? It's a mapping question and moving it there would mean more people get to see this.

I'm pretty confident this is a leak. Look at the top of your compile log for ***LEAKED*** and there'll be a clue as to where the issue is. Seeing as there's not much else it can be (as far as I'm aware), you might as well just be going to View -> Load Pointfile to find the leak rather than recompiling just to do that again.

And to make sure you're aware, leaks are when your level isn't sealed off from the void (which causes nasty issues). Things like props, point entities and brush entities won't seal your map either, they have to be solid brushes with all their faces being non-transparent.

If you press "Copy to Clipboard" at the bottom of your compile log when you press "Run Map", you can paste it into this site and it will tell you what problems your map has. It's pretty useful, and it can help you with some stuff.
