Televisions, dev_tvmonitor1a

I created a map with two brushes for television screens, two cameras, and one of the televisions works correctly.

The other television does not work correctly.  It has the image of the first television scrolled slightly.  After a while, I realized the camera was reading what it saw into one texture (dev/dev_tvmonitor1a), which was applied to both screens.  The second screen, being slightly to the left and having its texture alignment set to 'World', was repeating the texture as it should.  So, in order to have two screens displaying two different images, you need two different textures.

I tried creating a new texture and applying it to the face of the second screen.  However, it didn't display what the camera saw, it only displayed the texture.

I assume there are special parameters applied to the .tga and the .vmt that tell Source, 'I'm a camera screen', but I can't unpack the game textures to see what they are.  If someone does know--what they are, or how to unpack the game textures to look--let me in on the secret.

If you open the "source materials.gcf" file with GCF Scape, you will
find the textures and their related .vmt files. You can open the .vmt
files in any text editor. Camera textures have "_rt_Camera" set as the
$baseTexture.

See this
article for a list of the textures set up this way, and their
effects on the camera display. However, I haven't managed to get
multiple simultaneous camera feeds even when using two cameras, two
screens, and two different textures.

I will try my hand at making multiple screens, but if it doesn't work, I will scrap my idea all together.

In any case, it was a valuable learning experience. Thank you for your help.

No dice, but I understand how it works, now.
