How do I apply a tools/skybox texture to a func_brush?

[The Maestro]

When I try to do this, the literal tools/skybox texture (blue texture that says "SKYBOX") appears in-game.
The reason that I'm trying to do this is that I want to be able to walk through the skybox.

Is there anything other than a func_brush that can have a skybox applied to it and allow players to walk through?

Any ideas?

Thanks!

You would need to make a custom vtf and vmt but you could just apply it to the brush face and stretch it.

That sounds good. How would the vmt file look?
What would I set as the vtf?
Thanks.

You want to duplicate the exisiting skybox you want and uncheck all the flags. Make sure you rename of the skybox to something else so It doesn't get overwritten Maybe like fakesky_back, fakesky_left, ect...

Going off that fakesky_back example your vmts will look similar to this.

"UnlitGeneric"
{
    "$nofog" "1"
    "$ignorez" "1"
    "$basetexture" "<yourdirectoryforthetexture>/fakesky_back"
}

Afterwords you will have 6 new textures and vmts to assign to your map.

you can't func_brush the skybox. the map will leak. there's just void behind it. no point walking thru that.

You understand you dont need to make the walk-through skybox brush part of the actual skybox enclosing right?

Thanks you for your help, everyone!
