create an invisible skybox

I would like to create an invisible skybox and I wonder if it is possible.

What do you mean by invisible ?
You could just make a custom skybox with 6 white texture. So you have a totally white skybox.

Invisible skybox doesnt really make sense, as your map skybox brushes need to display something.

Technically, you can have an invisible skybox. Probably isn’t what he wants, though.

looks fine to me

what I want to do is hide the skybox because the real skybox is a prop.

If the skybox is a prop that covers a 360 degree view, then just make a normal skybox with the skybox texture.

Use 2dskybox texture instead of toolsskybox
