ok... i put 1 in my map and it breaks the whole thing... it sais that none of my enteties have a visible brush... but they do, cause it worked before i put the brush in... help?

(P.S. i may be doing the clip brush wrong... so meh...)

A clip brush (i.e. the one just covered in the texture named clip) cannot be an entity or it will cause an error. This form blocks players but not weapons. If you want one that blocks shots and such you can use a func_wall with the null texture (or any material if you're clipping a model) and then set it to a rendermode "texture" and amount "0".

Make sure all the sides are covered in the CLIP texture.

thanks alot
