This page describes a module within the HTrace: World Space Global Illumination (WSGI) asset. It provides indirect lighting inside Unity HDRP's native ray-traced reflections. This module is exclusive to Patreon.
Please keep in mind that this approach comes with trade-offs and may not be suitable for all projects.
Setup
Download the HTrace WSGI package containing the Reflection module through Patreon, and install it in your project. Once installed, you should see a new foldout in the HTrace UI called Reflection Indirect Lighting.
Enable Unity’s ray-traced reflections and set the tothe Performance mode.
Set the Indirect Evaluation Method dropdown in the HTrace UI to either Tracing or Approximation.
Indirect Evaluation Method set to None
Indirect Evaluation Method set to Tracing + DLSS used as a denoiser
Indirect Evaluation Method set to Approximation
Indirect lighting is only visible within the first bounce of ray-traced reflections. Recursive bounces are not supported at the moment. For multiple bounces, consider using reflection fallbacks such as the sky or reflection probes.
