Ray-traced effects

The High Definition Render Pipeline (HDRP) uses ray tracing to replace some screen space effects, shadowing techniques, and Mesh rendering techniques.

Page	Description
Ray-Traced Ambient Occlusion	Use ray tracing data to generate ambient occlusion.
Ray-Traced Contact Shadows	replaces contact shadows with a more accurate, ray-traced, contact shadow technique that can use off screen data.
Ray-Traced Global Illumination	Use ray tracing data to generate global illumination.
Ray-Traced Reflections	Use ray tracing data to generate reflections.
Ray-Traced Shadows	Use shadows generated from ray-traced directional, point, and area lights.
Use the recursive rendering volume override	Trace a high number of rays that bounce multiple times.
Ray-Traced Subsurface Scattering	Use ray tracing data to generate subsurface scattering.
