Point_Camera/Func_Monitor Cause Crash.

Hey guys, I’m trying to make a map that uses a point_camera to display what it views on a func_monitor brush. This works perfectly in hl2 deathmatch (Which I test my gmod maps in), but when I test it in Gmod, it crashes as soon as it finishes loading the map.

Is there anyway to fix this, or are there any alternate ways to get the same system to work for Gmod?

Cheers guys.

Might want to post here instead. http://www.facepunch.com/forums/38-Mapping
