You can use the stack property add Overlay cameras to the stack and they will render in the order as defined in the stack. For more information on configuring and using Camera Stacks, see [Camera Stacking](camera-stacking.md).

__Important note:__ In this version of URP, Camera Stacking is not supported when using the 2D Renderer or when using the VR Multi Pass mode. Support for these will be added in upcoming versions of URP.

__Important note:__ In this version of URP, Camera Stacking is not supported when using the 2D Renderer or when using the VR Multi Pass mode. Support for these will be added in upcoming versions of URP.

When you use [Camera Stacking](camera-stacking.md), the [Base Camera](camera-types-and-render-mode.md#base-camera) of a Camera Stack determines most of the properties of the Camera Stack. Because [Overlay Cameras](camera-types-and-render-mode.md#overlay-camera) can only be used as part of a Camera Stack, you can configure only a limited number of settings on an Overlay Camera. Overlay cameras not assigned to a camera stack will skip rendering.

The Camera Inspector has the following sections when the Camera has its Render Mode set to Overlay. To read more about a section, click the corresponding link below, or scroll down on the page:

# Camera Stacking
In the Universal Render Pipeline (URP), you use Camera Stacking to layer the output of multiple Cameras and create a single combined output. Camera Stacking allows you to create effects such as a 3D model in a 2D UI, or the cockpit of a vehicle.

__Important note:__ In this version of URP, Camera Stacking is not supported when using the 2D Renderer or when using the VR Multi Pass mode. Support for these will be added in upcoming versions of URP.

A Camera Stack consists of a [Base Camera](camera-types-and-render-type.md#base-camera) and one or more [Overlay Cameras](camera-types-and-render-type.md#overlay-camera). A Camera Stack overrides the output of the Base Camera with the combined output of all the Cameras in the Camera Stack. As such, anything that you can do with the output of a Base Camera, you can do with the output of a Camera Stack. For example, you can render a Camera Stack to a given render target, apply post-process effects, and so on.
