Helps the shader guess how "thick" an object is on your screen. Adjust this if you notice light leaking behind thin objects like pillars or character limbs.
While true multi-bounce ray tracing is too heavy for real-time post-processing, RTGI 0.36.1 uses clever mathematical approximations to simulate the soft, ambient scattering of secondary light.

: Under the Generic Depth settings, you will see several depth buffers listed. Select the one that matches your game's resolution and shows the most "movement" when you move your character. Check Preprocessor Definitions
The latest update for is version 0.36.1 , which introduces several quality-of-life improvements and performance optimizations for real-time ray-traced global illumination. Key Updates in RTGI 0.36.1 Extract the files into your game’s reshade shaders
Version 0.36.1 introduced critical optimisations, better denoising filters, and refined temporal accumulation. This allows the shader to simulate authentic light bounces, deep ambient occlusion, and accurate color bleeding with far fewer visual artifacts than earlier builds. Key Features of the 0.36.1 Build
Ensure "Generic Depth" is enabled. You may need to toggle settings like Copy depth buffer before blend operations or check Reversed Depth depending on how the game engine handles 3D space. Key Settings and How to Tweak Them
RTGI 0.36.1 is a specific, stable release of the ReShade Ray Traced Global Illumination shader package, designed to simulate realistic light bouncing—where light hits a surface and casts color onto surrounding objects—in real-time.
While newer versions of RTGI exist, is often regarded as a particularly stable and robust "classic" iteration in the shader's evolution.
