Custom maps not loading/missing skybox issue

[schirpich]

I've been trying to figure out why the skybox for downloaded maps simply won't load. Maybe it's missing, I don't know. fy_iceworld in particular and several others. Anyone who connects to the server gets that screwed up blur/glitch sky.

I've attached a screen shot. Something tells me this is an extremely easy fix, but I think I've just been looking in the wrong places and wrong terminology.

Some maps do this, and some don't. But for the one's that do have the problem, is there anything I can do to fix it? Or is it just a screwed up map that I downloaded?

Here's my server info/stats. Let me know if there is anything else I need to provide.
