The RTGI 01702 Release is a specific, highly-regarded iteration of the ReShade Ray Traced Global Illumination (RTGI) shader. Created by Pascal Gilcher (widely known as Marty McFly), this shader physically simulates how light bounces off objects in real-time, bringing high-end lighting effects to games that lack native ray tracing support.
While modern versions of the iMMERSE RTGI suite focus on efficiency and noise reduction, the 01702 build remains popular due to its unique visual character—specifically its grit, soft shadow transitions, and "lived-in" color bleeding that some users feel newer, cleaner path tracers lack. Common Issues and "Release Fixes"
Despite its visual appeal, RTGI 01702 is a post-processing effect that relies on a game's depth buffer. Most "fixes" for this version involve restoring access to that data or correcting alignment issues.
Depth Buffer Restoration: If the lighting appears flat or only affects certain objects (like the protagonist's hands), the depth buffer is likely blocked.
The Fix: In the ReShade menu, go to "Edit global preprocessor definitions." Toggle RESHADE_DEPTH_INPUT_IS_REVERSED between 0 and 1.
In-Game Settings: Disable Temporal Anti-Aliasing (TAA) and MSAA in your game's internal settings, as these often conflict with depth buffer access.
Shader Misalignment: If the lighting seems "offset" from the actual geometry, the Immerse Launchpad (the prerequisite shader) may be in the wrong order. rtgi 01702 release fix
The Fix: Ensure the Launchpad shader is active and positioned at the very top of your shader list in the ReShade UI.
Compile Errors: Some users report "Failed to compile" messages for secondary effects like dh_Lain.fx.
The Fix: Most of these are non-critical. If the main RTGI shader is working, these secondary errors can often be ignored as they aren't essential to the lighting effect. Key Features of RTGI 01702 Devlog July 2023 - MARTY'S MODS
The RTGI 0.17.0.2 update for ReShade, released by Pascal Gilcher (Marty McFly) on October 30, 2020, was a maintenance patch primarily focused on fixing stability and installation issues for the Ray Traced Global Illumination shader.
As this version is now several years old, it is considered outdated compared to current releases like iMMERSE Pro: RTGI. Key Fixes and Features in 0.17.0.2
While the full detailed changelog is typically hosted on the Marty's Mods Patreon for subscribers, the release addressed the following: The RTGI 01702 Release is a specific, highly-regarded
Shader Compilation Stability: Fixed common errors during initial shader loading in ReShade.
Performance Optimizations: Minor adjustments to the ray marching logic to improve frame times on mid-range hardware.
Depth Buffer Compatibility: Improved "Generic Depth" detection, reducing instances where the shader would fail to display the depth map correctly. Troubleshooting "RTGI 0.17.0.2" Issues
If you are specifically using this older version and encountering bugs, the community typically recommends the following "fixes":
Depth Buffer Fix: Open the "Edit global preprocessor definitions" in the ReShade menu and toggle RESHADE_DEPTH_INPUT_IS_REVERSED between 0 and 1. This often fixes the "empty" or "black" lighting channel.
UI Interference: If the lighting effect bleeds through the game's HUD, ensure you are using a UI mask or lower the "Bounce Lighting Intensity" below 2.0. Game Development : If RTGI refers to a
Generic Depth Check: In the ReShade "Add-ons" tab, ensure "Copy depth buffer before clear operations" is checked to allow the shader to see the 3D data of the game. How to Access Latest Versions RTGI 0.17.0.2 Release! - Patreon
Game Development: If RTGI refers to a game engine feature like Real-Time Global Illumination, then "RTGI 01702 Release Fix" could be a patch to fix issues related to lighting in a game.
Software Development: In a broader software development context, this could refer to a patch or update to fix bugs or improve performance related to a specific feature or component.
Verify the error context
Check the full stack trace. Look for the phrase Release lock held by PID:XXXX. If present, note the process ID.
Assess rollback readiness
Ensure the previous working release is available. Run:
rtgi-cli --list-releases
If the previous release is intact, consider rolling back first.
