Ray-Traced Reflections

Ray-Traced Reflections is a ray tracing feature in the High Definition Render Pipeline (HDRP). It is an alternative, more accurate, ray-traced solution to Screen Space Reflection that can make use of off screen data.

For information about ray tracing in HDRP, and how to set up your HDRP Project to support ray tracing, see Getting started with ray tracing.

Using Ray-Traced Reflections

Because this feature replaces the Screen Space Reflection Volume override, the initial setup is very similar. To setup ray traced reflections, first follow the Enabling Screen Space Reflection and Using Screen Space Reflection steps. After you setup the Screen Space Reflection override, to make it use ray tracing:

1. In the Frame Settings for your Cameras, enable Ray Tracing.
2. Select the Screen Space Reflection override and, in the Inspector, enable Ray Tracing. If you do not see a Ray Tracing option, make sure your HDRP Project supports ray tracing. For information on setting up ray tracing in HDRP, see Getting started with ray tracing.

Properties

HDRP implements ray-traced reflection on top of the Screen Space Reflection override. For information on the properties that control this effect, see Ray-traced properties.
