Underwater view

To change the area where the camera displays an underwater view for a non-infinite water surface, use the Volume Bounds setting. Follow these steps:

  1. Create a GameObject with a collider component, for example a cube with a Box Collider component.
  2. Place the GameObject where you want the underwater view to be visible.
  3. In the collider component, select Edit Collider to set the size of the visible underwater area.
  4. Select the water GameObject.
  5. In the Inspector window, under Appearance, under Underwater, set Volume Bounds to the GameObject you created.

To set the area of the underwater view for an ocean, follow these steps:

  1. Select the ocean GameObject.
  2. In the Inspector window, under Appearance, enable Underwater.
  3. Adjust Volume Depth.

If you look directly upward at the water surface from below, you may see a square border around the scene view. This is normal. It is because HDRP can only use screenspace data underwater.
