 # Contact Shadows
 The Contact Shadows [Volume Override](Volume-Components.md) specifies properties which control the behavior of Contacts Shadows. Contact Shadows are shadows that The High Definition Render Pipeline (HDRP) [ray marches](Glossary.md#RayMarching) in screen space inside the depth buffer. The goal of using Contact Shadows is to capture small details that regular shadow mapping algorithms fail to capture.

-To use Contact Shadows in your Scene, you must first enable them for your Cameras. In the Inspector for your HDRP Asset, go to the **Default Frame Settings > Lighting** section and enable the **Contact Shadows** checkbox. All Cameras can now render Contact Shadows unless you override a Camera’s individual [Frame Settings](Frame-Settings.md).

For information about how SSR works in HDRP, see the [reflection documentation](Reflection-in-HDRP.md#ScreenSpaceReflection).

+To use this feature in your Scene, you must first enable it for your project and then enable it for your Cameras. To enable features in your project, you use the [HDRP Asset](../HDRP-Asset.md) and to enable features for your Cameras, you use [Frame Settings](../Frame-Settings.md). You can enable features either for all Cameras, using the Default Frame Settings, or for specific Cameras, by overriding each Camera's individual Frame Settings.
