(URP), multiple Base Cameras or Camera Stacks can render to the same render target. This allows you to create effects such as split screen rendering.

in the overlapping area multiple times. Unity draws the Base Camera or Camera Stack with the highest priority last, on top of the previously drawn pixels. For more information on the camera render order optimization, refer to Understand camera render order.

    , scroll to the Output section. Change the values for Viewport rect to the following:
    • X: 0
    • Y: 0
    • W: 0.5
    • H: 1
  3. Create another Camera in your scene. Its Render Mode defaults to Base, making it a Base Camera.
  4. Select the Camera. In the Inspector, scroll to the Output section. Change the values for Viewport rect to the following:
    • X: 0.5
    • Y: 0
    • W: 0.5
    • H: 1

Unity renders the first Camera to the left-hand side of the screen, and the second Camera to the right-hand side of the screen.

You can change the Viewport rect for a Camera in a script by setting its rect property, like this:

myUniversalAdditionalCameraData.rect = new Rect(0.5f, 0f, 0.5f, 0f);
