This ticket is closed because transparency is already supported in 6000. How to enable transparency 1.

Post Processing Universal Render Pipeline Asset > Post-processing > Enable Alpha Processing

How to reproduce:
1. Open the user-attached project “OverlayURP”

3. Open “OBS” and add “Window” or “Game” capture of built Player
4. Add any other capture and make sure it is below the Player
5. On the Player capture enable transparency by clicking on it → Properties → “Allow Transparency”
6. Observe the captured video preview
Expected result: Only the cube is captured in Player and the other window is seen below it
Actual result: The cube and the background are captured covering the other window
