# Set up a camera stack
|
||
|
|
|
||
|
|
This page describes how to use a camera stack to layer outputs from multiple cameras to the same render target. For more information on camera stacking, refer to [Understand camera stacking](cameras/camera-stacking-concepts.md).
|

|

|
|
Follow these steps to set up a camera stack:
|
||
|
|
|
||
|
|
1. [Create a camera stack](#create-a-camera-stack).
|
||
|
|
2. [Set up layers and culling masks](#set-up-layers-and-culling-masks).
|
||
|
|
|
||
|
|
## Create a camera stack
|
||
|
|
|
||
|
|
Create a camera stack with a Base Camera and one or more Overlay Cameras.
|
||
|
|
|
||
|
|
For more information on how to do this, refer to [Add a camera to a camera stack](cameras/add-and-remove-cameras-in-a-stack.md#add-a-camera-to-a-camera-stack).
|
||
|
|
|
||
|
|
## Set up layers and culling masks
|
||
|
|
|
||
|
|
Once you create your camera stack, you must assign any GameObjects the Overlay Cameras need to render to a [layer](xref:Layers), then set the **Culling Mask** of each camera to match the layer.
|
||
|
|
|
||
|
|
To do this use the following steps:
|
||
|
|
|
||
|
|
1. Add as many layers as your project requires. For information on how to do this, refer to [Add a new layer](xref:create-layers).
|
||
|
|
2. For each GameObject you want an Overlay Camera to render, assign the GameObject to the appropriate layer.
|
||
|
|
3. Select the Base Camera of your camera stack and navigate to **Rendering** > **Culling Mask** in the Inspector Window.
|
||
|
|
4. Remove any layers you don't want the Base Camera to render, such as layers that contain objects only an Overlay Camera should render.
|
||
|
|
5. Select the first Overlay Camera in the camera stack and navigate to **Rendering** > **Culling Mask** in the Inspector window.
|
||
|
|
6. Remove all layers except for the layers that contain GameObjects you want this camera to render.
|
||
|
|
7. Repeat Step 5 and Step 6 for each Overlay Camera in the camera stack.
|
||
|
|
|
||
|
|
> [!NOTE]
|
||
|
|
> You don't need to configure the **Culling Mask** property of the cameras. However, cameras in URP render all layers by default, so rendering is faster if you remove layers that contain unneeded GameObjects.
