Also the walls are so bare, you should add like a pattern on the top or bottom or middle etc… Makes it a bit more interesting.
Ok
I did the map just in ~2 weeks, it’s very quick to do a map without no defects :D, and the level design was’nt my primary obj.
The mirrors don’t work because a hall of mirrors effect is NOT possible, aka 2 mirrors facing each other. That just breaks. Even 2 mirrors at a 90 degree angle tend to give problems.
Thanks, i did’nt no why they don’t work.
You should try some other compile options too, the lighting is nonexistent and the vis was the first thing I noticed. (There’s a room floating around in the sky)
That’s normal, because i compil in ‘Test’, i know it’s not the best but I can’t test my map in local, I always test it directly on the server so i compiled it in Test format x) The map havn’t Light.
Also in said room you have a glass wall, you should put the nodraw texture on the inside of the glass if you know what I mean, atm you can see the lines where 2 brushes meet, if you make these surfaces nodraw then the glass seems like it just flows into each other
Thansk, i’ve tried the clip texture but i put it on the wrong side of the brush ! 
Thanks for your comment
