 To begin, your render pipeline needs to maintain at least one instance of [RenderGraph](../api/UnityEngine.Rendering.RenderGraphModule.RenderGraph.html). This is the main entry point for the API. You can use more than one instance of a render graph, but be aware that Unity does not share resources across `RenderGraph` instances so for optimal memory usage, only use one instance.

 ## Custom Pass AOVs
 You can use AOVs to output the results of [custom passes](Custom-Pass.md). In particular, you can output the cumulative results of all custom passes that are active on every custom pass injection point. This can be useful to output arbitrary information that custom passes compute, such as the Object ID of the Scene GameObjects.

 By default AOVs are rendering at the precision and format selected in the HDRP asset. If the  AOVRequest is configured with *SetOverrideRenderFormat* option set to true, then rendering will use the same precision as the user allocated AOV output buffer.

-Only one Light can cast Contact Shadows at a time. This means that, if you have more than one Light that casts Contact Shadows visible on the screen, only the dominant Light renders Contact Shadows. HDRP chooses the dominant Light using the screen space size of the Light’s bounding box. A Directional Light that casts Contact Shadows is always the dominant Light.

 **Note**: A Light casts Contact Shadows for every Mesh Renderer that uses a Material that writes to the depth buffer. This is regardless of whether you enable or disable the **Cast Shadows** property on the Mesh Renderer. This means that you can disable **Cast Shadows** on small GameObjects/props and still have them cast Contact Shadows. This is good if you do not want HDRP to render these GameObjects in shadow maps. If you do not want this behavior, use Shader Graph to author a Material that does not write to the depth buffer.
