When it comes to the RTGI shader, this error usually triggers for a few specific reasons:
Hello,
Often, the washed-out look is caused by ReShade not correctly interpreting the game's depth buffer. Open the ( Home key by default). Go to the Add-ons tab. Click on Edit global preprocessor definitions .
Hardware anti-aliasing completely destroys depth buffer visibility. Switch to FXAA or use external injection like Nvidia DLSS/AMD FSR.
RTGI 01702 requires modern ReShade hooks to function correctly. Using an outdated injector will break the shader compilation. you are using ReShade version 5.8.0 or higher. Ensure you downloaded the version with full add-on support .
Different game engines store depth information differently. You must tell ReShade exactly how to read it by editing the global values in the tab.
The "Precise Light Spreading" setting can sometimes , while disabling it removes some RTGI shadows.
A milky, gray overlay that reduces contrast and destroys blacks. Performance drops: Higher-than-normal GPU usage. Shimmering/Noise: Unstable lighting behavior.
Blur algorithms smear the depth information, leading to horrific ghosting trails behind moving objects.
Most 01702 errors stem from residual files left behind by older RTGI versions. to your game's executable ( .exe ) directory. Delete the old reshade-shaders folder entirely. Remove any old qquint.fx or qquint_rtgi.fx files.
Use the RTGI (Diffuse) Guide for specific settings on smoothed and textured normals to hide blocky geometry.
To help narrow down the exact cause of your shader issue, please let me know: What are you trying to mod?
: Some users report "Failed to compile" messages for secondary effects like dh_Lain.fx .
