Engine: Unreal Engine 5.8.1, Windows 64-bit, deferred renderer (GBuffer). SM5 compute. No hardware ray tracing / RT cores.

Distribution: Code-only plugin. Enabling it does not add maps, meshes, or files to the project Content/ folder and does not overwrite user folders. Example levels are not in this package; a separate example project will be linked when available.

What it does: Radiance Response Field GI. GPU-bake a surface voxel field, evaluate it at runtime, optional HDRI/color ambient fill, and selectable denoise (Off, Bilateral, A-trous, NLM, Wavelet). Can replace Lumen GI/reflections on the view (r.RRFGI.ReplaceLumen, default on).

Setup:

Enable RRF-GI in Edit → Plugins and restart if asked.
Place an RRFGI Volume around the space.
Capture Fallback Field (GPU bake).
Store GI to keep the bake in the level (compact blob on the volume, not a new Content asset).
Optional: Ambient and Denoise under the volume / Project Settings → Plugins → RRF-GI.

Not included: Third-party libraries, fonts, audio, or marketplace content. All plugin code is 3DAW; engine modules are Epic.
