Cubemap not showing up in Level Editor?

[Romulator]

Okay, I think I know what the problem is (what I state below is not the problem, but should be fixed). Did you make or download this skybox from somewhere in particular? Also, did you edit it a certain way (other than in GIMP, I mean, something like, resizing or cropping).

In simple, one problem is the sizing of the "long" image.



The solid black lines, are 256*256 pixels. The image isn't a simple "move this over a few pixels" to fix though. Some of them are stretched and others are too short.
