HTrace: Screen Space Global Illumination HDRP

A fully dynamic HDRP screen-space GI system that adds bounce lighting, emissive contribution, and detailed secondary shadows without a bake-first workflow.

HTrace: Screen Space Global Illumination HDRP adds responsive indirect lighting to HDRP scenes, helping materials and environments react more naturally to the light already present on screen.

It is built for dynamic production workflows where lighting, objects, and materials can keep changing, while artists still need clean, stable, and controllable results.
