This is probably a bit of a simple question but I did my best to find an answer.

Is there a way to remove, or flag the unseen faces of a brush unrendered? If so, how?

Thanks a lot!

Normally the level compiler removes the unseen faces automaticly, but with this you can be sure.

Ahh, so if I understand this correctly, simply make all unseen faces a sky. Works similair to GoldSrc's Null texture.

Thanks a lot!
