Put your overlays on stream

An overlay on your desktop sits in one place, and one place can't suit a vertical stream and a horizontal one at the same time. So instead of OBS capturing the overlay off your screen, OBS fetches it from AB Racing Line and you place it in each scene however you like. Your own screen isn't touched.

You need: AB Racing Line and OBS on the same PC Time: 5 minutes

What you'll do
  1. Copy an overlay's address in AB Racing Line.
  2. Add a Browser source in OBS and paste it.
  3. Size it, place it, and repeat for each scene.

Step by stepAdd an overlay to OBS

Copy the overlay's address

In AB Racing Line, open AB Overlays and click the cog on the card of the overlay you want, then Copy OBS browser address.

The address goes to your clipboard, and the panel shows it back with the size the overlay is designed at. Note the size: you'll use it in OBS.

Add a Browser source in OBS

In OBS, in the scene you want the overlay in, click + under Sources and choose Browser. Give it a name (the overlay's name is a good one) and press OK.

Paste the address and set the size

In the Browser source's settings, paste the address into URL, set Width and Height to the size the panel showed, and press OK.

Any size works. The overlay keeps its own shape inside whatever size you give the source, and the spare space is see-through, so it never stretches. Starting at the recommended size just means none of the source is wasted.

Place it, and repeat for each scene

Drag and resize the source in OBS like any other. Add the same address to your other scenes, vertical and horizontal, each placed its own way: they all show the same live overlay.

If it goes wrongQuick fixes

The source is blank, black, or frozen on an old picture
Right-click the source in OBS and choose Refresh. If that doesn't do it, close OBS and open it again. Don't delete and re-add the source: a refresh brings it back with the same address.
The overlay shows, but no telemetry
Open http://127.0.0.1:8722 in a browser on the same PC. It tells you whether telemetry is arriving, how recently, and which sources OBS is reading. Usually iRacing isn't running, you're not in a session yet, or AB Racing Line was closed after you pasted the address.
The overlay looks stretched or squashed
That's OBS scaling the source. Right-click it, then Transform → Reset Transform.
