This guide was written for OBS Studio ver 25.0.1.
How do I set up the XPN Overlay with OBS?
To get started, click on the Overlay on the left bar.
Click on the URL chain button to copy and paste the link in Lightstream.
Now go into your OBS Studio, click the + sign under your Sources, and select Browser.
Name the source whatever you like and click OK.
In the "Properties" screen, paste the URL you copied earlier from XPN into the URL field. Under Width & Height, please make sure that it’s the same resolution of the overlay. By default it is set at 1920x1080 but you can always change it to match your scene.
That’s it! You have successfully added the Overlay to OBS Studio.
