| Parameter | Function | | :--- | :--- | | | Maximum distance a ray travels to find a surface. Higher = more bounce light but more performance cost. | | Intensity | Strength of the indirect lighting contribution. | | Bounce Count (Hidden) | Fixed in v0.33 to 1-2 bounces for performance reasons. | | Temporal Factor | How much the current frame blends with previous frames to reduce noise. | | Quality Mode | Low (performance) vs. High (visuals). High used 4 rays per pixel. | | AO Mix | Blends traditional ambient occlusion with ray traced AO for cleaner shadows. | Share your results and custom settings in the comments below

(Ray Traced Global Illumination) is a specific shader developed by Marty McFly. Unlike simple color grading or ambient occlusion (AO) shaders, RTGI simulates how light bounces off surfaces to create realistic indirect lighting and shadows.
