[Request] "Fixed" sky_nightfall_01

I was planning on using the sky_nightfall_01 skybox in a map but for some reason about halfway down the skybox fades to white, this is covered up by a 3dskybox in maps like Probed and Doublecross. If possible could someone make a skybox that does not have the white side and potentially a bottom side. Ideally it would fade into a grey for the bottom half of the sides and the bottom face of the skybox. Here is an example of the problem:



Thanks in advance

Tried that before,



it has a similar effect but it is slightly less obnoxious than the white, the main reason is I would much prefer the starry night sky over the cloudy overcast one that sky_night_01 has.

At this point it's looking like just finding a custom skybox would be a better option or having some raised buildings or something behind the main play area to prevent horizon stuff from coming into play in the first place. Either way thanks for the quick responses and good information.
