Add VirtualCam as a Browser Source
Open the Streaming screen and click “Add to OBS”. Copy your personal source URL, then in OBS add a Browser source (Sources → + → Browser) and paste it in. Set Width 1024 and Height 768 - any 4:3 size works.
The source shows your live character output whenever you're backstage, and a VirtualCam standby card the rest of the time. From there, use OBS's Virtual Camera to appear as a normal webcam in any app, or drop the source straight into your stream layout.
Your source URL is a private link - anyone who has it can watch your output. If it leaks, regenerate it from the “Add to OBS” dialog (old links stop working immediately).
