Please Note: If you have recently added Sources and they are not displayed, click the Refresh button on

the script to reload it. A script dialog box may appear, but you can just close it. The new

sources should now be visible. 

5. Assign Sources to a tally light. For example, the first source “Image 1” can be mapped to tally light 1 by setting its value to “1”.

Please Note: Multiple sources can be mapped to the same tally light. This tally will be

illuminated when any of the sources are placed in program or preview mode. For best results, use a separate Scene for each camera feed.

6. The setup is complete. The emitters will now trigger when set to Program and Preview through OBS.OBS Controller Testing.
