Where's my skybox brush?

So I opened up my map in Hammer today only to find that the brush I’d textured with the toolsskybox material wasn’t there. I changed the skybox material in map properties, compiled the map and ran it. It worked fine, but the brush still isn’t there in Hammer. I can see the wireframe outline of it, but I can’t select it, and can’t select its faces in the texture application tool.

Any ideas?

That’s the cordon tool, turn it off.

Oh…

OH.

Thanks. :downs:
