As of Unity 2019.3.7f1, the Verified version is v7.1.8, so you'll need to expand the ▶ to the left of the Universal RP to find the latest version.

1. Select Overlay to Render Type field of Camera component.
2. Add AddOverlayCameraToCameraStack component.

• AddOverlayCameraToCameraStack component will find Overlay Camera automatically from same GameObject on runtime. You can also set Overlay Camera manually.
  • Set field automatically when component attached (and invoked Reset).
• Overwrite Render Type to Overlay on runtime if Overwrite Render Type field is set to true.

Add Overlay Camera into Camera Stack of Base Camera automatically.

The base camera to be added is selected with the highest Priority value.

This is directly due to the process of adding a Camera managed by the AddOverlayCameraToCameraStack Component to the Camera Stack of Base Camera.

When looking for a Base Camera to add, you can use Camera.depth (the value that appears as Priority in the Inspector.) values in descending order, the first one is used.

Therefore, it is recommended to set a large value in Camera.depth to fix the camera to be added correctly.
