Sky box problems

[VctrEco12]

Ok I have made sky boxes before and they have always worked in the past. But a couple days ago they just stopped working. I would test the map and where the sky box should have been there was just blackness. Any ideas what Im doing wrong?

Not without seeing it.

Make sure its in its own zone, and the setting on the skybox Info are all right.
