    ...is showing my 3D skybox.

    Am I doing it wrong, or something?

    Can you explain a bit more about what is going on?

    I have a 3D skybox with stuff in it. I have a skylight with a tools/toolsskybox2d. If I look at said skylight in-game, I can see the stuff I placed in the 3D skybox. I was under the impression that that was contrary to the purpose of that texture.

    I think 2D and 3D skybox textures can't be used in the same Veiw...thingy. I forget the technical term, but basically you have to never be able to see them both at the same time, in vvis terms. Same as with two levels of water: it's only possible if you can't see both at once.

    EDIT: PVS https://developer.valvesoftware.com/wiki/PVS

    You can see 2 levels of water in any one area, they just can't both be expensive materials.

    Are you sure about that? I'm quite sure I've done it in the past. Although, that would explain the funny natur eof it.

    By gum, you're right. I found the page in the developer wiki on tool textures, and that's what it said.

    Although I swear some of my 2D skybox textures are nowhere near my regular ones. Am to assume the problem chains, as in a 2D skybox texture can't be in the same PVS as another 2D skybox texture that was in the same PVS as a regular one, either?

    I think the engine just doesn't consider the stuff in the 3d skybox visible when looking thru a 2d skybox brush. But the stuff will still draw if another brush says that the 3d skybox is visible. The engine either sees the 3d skybox or it does not.
