Radiant Global Illumination

Real-time global illumination, no baking required.
Radiant GI is a full-screen post-processing effect that adds bounce lighting to your scene on the fly, producing better-lit, more natural and realistic results - on any scene, static or dynamically generated, with no scene or material changes.

This bundle contains 2 packages optimized per pipeline:
- Radiant GI for URP (Universal Rendering Pipeline).
- Radiant GI for built-in pipeline.

Global illumination is the indirect light that bounces off surfaces and softly fills your scene, the way it does in real life. Radiant computes it automatically and very fast, then blends it with Unity's regular lighting.

** Lighting quality **

- Realtime GI - no baking, works with any 3D scene including dynamically generated content.
- Works with any light type and emissive surfaces - every pixel can contribute to GI.
- Noise-free raymarched technique using custom bilateral, wide-blur and spatio-temporal filters.
- One light bounce option for extra indirect lighting.
- Reflective shadow maps and reflection probes as fallbacks for off-screen emitters.
- "Near Field Obscurance" darkens occluded surfaces for added depth.

** Artistic control **

- Virtual emitters ("GI injectors") - drop them in the scene or attach to dynamic objects to fake artificial lighting.
- "Organic Lighting" - a performant way to inject procedural lighting (deferred only) that also feeds indirect light for richer environments.
- Fully customizable raymarching, performance and artistic settings.
- Volume system - apply globally or per zone with custom settings each.
- Debug and compare visualization tools (Beautify-style compare mode).

** URP & compatibility **

- Adaptive Probe Volumes support (URP).
- Occlusion maps support (URP).
- Transparent surfaces support (URP).
- Forward+ and Deferred+ support (URP).
- Compatible with forward or deferred rendering (deferred recommended for the most realistic results).
- Perspective and orthographic cameras.
- Compatible with Unity 2022.3 and Unity 6, including Render Graph.

Easy to set up: add the Radiant render feature and configure the post-processing effect in your volumes. Includes 2 demo scenes + documentation.
