I want to know whether I can build a skybox without first having a terrain. So basically I want to have a skybox as a fake backdrop on a large subtractive cube that I'll use for the level.
I want to know because I've got a flat terrain at the moment that I'm using for an alley map. I've added brushes on top of the terrain for the pavement and everything is fine until I add the building brushes on top of the pavement. The terrain either moves slightly down so it's not visible under the bottom of the subtractive cube or it disappears entirely.
Can anyone let me know what I'm doing wrong?
