Lighting bounces off surfaces to illuminate others.
Pascal Gilcher’s RTGI (often called the "Martys Mod" or "Screen Space Ray Tracing") is a shader that simulates and Ambient Occlusion . Unlike simple screen-space ambient occlusion (SSAO), RTGI traces rays in screen space to calculate how light bounces off surfaces. This adds realistic color bleeding (e.g., a red carpet making a white wall slightly pink) and deep shadows, creating volumetric depth that standard rasterization cannot achieve.

The transformation was instantaneous. It was as if the game had taken a deep breath and finally woke up. The Light:
To use the "full" or advanced versions of the shader, users typically follow these steps: Lighting bounces off surfaces to illuminate others
: Calculates soft, realistic shadows where geometric planes intersect. It handles dark crevices, clothing folds, and fine details with vastly superior depth compared to vanilla SSAO or HBAO techniques.
: Light bounces dynamically off colored surfaces to illuminate adjacent objects. For example, walking next to a bright red brick wall casts a subtle, realistic crimson hue onto a character's armor. This adds realistic color bleeding (e
Adjusts how bright the bouncing light effects appear in-game. Troubleshooting Common Issues
Increase this if you see too much "grain," but beware of losing small-scale lighting details.
