Giant Ugly Shadow Thing

[The Whole Team]

Near the blue spawn base is this:

I can't seem to get rid of the shadow no matter what I try! I don't even know whats causing it! Any help would be appreciated.

Also, just so you know, there are no leaks on the map.

If you have something in the 3D skybox, it WILL cast shadows in the normal area (not the other way around) so double check you haven't got something in the skybox thats casting it.

Seems the most likely thing to be causing this
