func_monitor is a brush entity available in all Source and Source 2 games except Left 4 Dead series. It displays a real-time scene captured from a point_camera somewhere else in the world.

In Source for the entity to work, the surface(s) on which the camera view will be displayed must have a material with $basetexture _rt_Camera. Stock materials that work are dev\dev_combinemonitor* and dev\dev_tvmonitor*.

Bug:Cameras may fail to network properly in multiplayer. See below for a code fix. Fixed in Team Fortress 2.  [todo tested in ?]

Note:Unless you set up multiple render textures in your mod's binaries, only one point_camera can be rendered at any one time. The first camera in the map will appear on all monitors.

Code:To enable monitors in your non-HL2 mod, you must:

• Include the entity's client .cpp file (found in \client\hl2\).
• Include the entity's server .cpp and .h files (found in \server\hl2\).
• #define USE_MONITORS at the top of \client\viewrender.cpp and \client\view.cpp.
• Fix a multiplayer bug in CPointCamera::CPointCamera() by setting m_bActive to true.
