Map skybox white on compile, but lighting still works.

[The Supreme Meme Lord™]

Hello,

I've been working on a map and upon compiling the map, which had no compile errors, the skybox was completely white. The only thing is, the skybox is not missing. It shows up in the Hammer++ preview and is named properly. The lighting on the map works fine as well, it just looks like you're staring in the abyss.

I haven't seen the error documented, but yet again, I could be blind when I tried to research it. Help would be appreciated.

Photos showing what it looks like:

you either have a leak, or have a typo in the skybox texture's name, or you are looking at nodraw with no skybox texture within the PVS
