How to block a laser beam?

I have a room where there is a glass, laser on its left side and turrets on the roghtr. I only use it so the player can see whats on the other side, but I dont want the player to be able to burn them with a laser-redirection-cube. I tried everything, funcdetail, a solid or a solid brush glass dont work. Also tried normal solid textured with noclip, nodraw, invisible, clip, blockbullets, but none of them worked. Only a solid textured with a solid can block it, or is there any way to keep it somehow transparent but to vlock the laser?

Hmm...I doubt this is the best way, but perhaps you could try having a func_brush with a solid texture, but with the alpha at 0?

Hear the turret, for it is knell. It summons thee to heaven, or to hell.

Won't a brush with the tools/toolsinvisible texture do this?

The glass models block lasers (eg: glass_192x128_b.mdl), or you could use a non-glass texture on a func_brush, with the "render mode" and "FX amount" fields filled in to make it transparent. FX amount should be lower number for more transparent, and higher for less. I forget the render mode needed for transparency, try "texture" for a start.

no, I tried everything: tools/ invisible, nodraw, clip, etc, also as solid / func_brush (solid) etc.
will try that alpha thing with a non-glass behind a glass block...

...but using a glass prop worked, thanks NocturnalGhost!
