01702 Release Fix | Rtgi

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.

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

Conclusion

The RTGI 01702 release fix is not merely about deleting a lock file; it requires systematic diagnosis of process state, cache integrity, and environment checksums. By following the step-by-step remediation guide above—starting with killing orphaned processes, removing stale locks, resetting state, and only purging as a last resort—you can recover your release in under 30 minutes.

More importantly, treat each occurrence of RTGI 01702 as a signal to improve your deployment automation. Idempotent scripts, pre-flight validations, and regular cache maintenance will transform this frustrating error into a rare historical footnote.

Next Steps: Audit your current release pipelines for the risk factors discussed. Schedule a game day exercise where your team practices the RTGI 01702 fix steps. And finally, open a ticket with your RTGI vendor to inquire about upgrading to a version with atomic release transactions.

RTGI 0.17.0.2 update is a specific beta release of the Ray Traced Global Illumination shader for ReShade, developed by Pascal Gilcher rtgi 01702 release fix

(also known as Marty McFly). This version, originally released around October 30, 2020, primarily addressed critical stability issues and depth buffer compatibility in the RTGI 0.17 series Context of the Release

RTGI is a screen-space ray tracing shader that adds dynamic global illumination, ambient occlusion, and lighting bounces to games that do not natively support ray tracing. Version 0.17.0.2 Fixes

: This was a "hotfix" release following version 0.17.0.1. It aimed to resolve issues where the shader would fail to compile on certain hardware or crash ReShade upon loading. Depth Buffer Importance

: Like most screen-space effects, RTGI requires access to a game's depth buffer to function. This specific fix improved how the shader interacted with the depth buffer detection in ReShade 4.8.x and above. Concept Paper: The Evolution of Post-Process Ray Tracing

, RTGI simulates path-traced lighting in a post-process environment. 1. Introduction

Traditional global illumination (GI) in older games is often baked or relies on low-fidelity screen-space ambient occlusion (SSAO). The development of the RTGI shader by Pascal Gilcher represents a paradigm shift, allowing real-time path-traced approximations in legacy DX9-DX12 titles 2. Methodology: Screen-Space Path Tracing

Unlike hardware-accelerated ray tracing (RTX/DirectX Raytracing), RTGI operates strictly on the information visible on the screen. It utilizes: Ray Marching:

Stepping through the depth buffer to detect geometry intersections. Denoising:

Filtering high-frequency noise inherent in low-sample-count ray tracing. Temporal Reprojection:

Reusing data from previous frames to stabilize the lighting solution.

The RTGI 0.17.0.2 release is a critical update for Marty McFly’s (Pascal Gilcher) Ray Traced Global Illumination shader, a popular ReShade add-on that brings realistic path-traced lighting to nearly any 3D game. This version was specifically released to address compatibility issues and "broken" lighting effects in certain titles, such as Alien: Isolation and older DX9/DX11 games. What is RTGI 0.17.0.2?

RTGI (Ray Traced Global Illumination) is a shader that calculates how light "bounces" off surfaces in real-time, adding depth, shadows, and color bleeding that typical game engines miss. Version 0.17.0.2 was a "fix" release designed to improve the shader's stability on newer ReShade builds and fix specific edge-case artifacts. Key Fixes in this Release The RTGI 01702 Release is a specific, highly-regarded

While primarily a maintenance update, the 0.17.0.2 release addressed several community-reported bugs:

Depth Buffer Alignment: Fixed issues where the ray tracing would "separate" or ghost at the edges of the screen, particularly when using ReShade 4.9.1.

Object Vanishing: Addressed a bug where objects would disappear or flicker when viewed directly through the shader’s light path.

Performance Stability: Refined the shader’s interaction with the ReShade API to reduce crashes in 32-bit and 64-bit environments. How to Install and Fix RTGI 0.17.0.2

To get the 0.17.0.2 "fix" working correctly, follow these steps:

Download Files: You must be a subscriber to Pascal Gilcher’s Patreon to access the official ReShade GI Beta 0.17.0.2.zip.

Update ReShade: Ensure you are using a compatible version of ReShade. While 4.9.1 was common at the time of release, many users now recommend ReShade with Full Add-on Support to avoid depth buffer glitches.

File Placement: Drag the Shaders and Textures folders from the RTGI zip into your game’s reshade-shaders directory. Configure Depth Buffer:

In the ReShade menu, enable DisplayDepth.fx to verify your depth buffer is visible.

If the screen is black or "split," disable in-game Anti-Aliasing (MSAA/TXAA) and Post-Processing, as these often block the data RTGI needs.

Subject: RTGI 01702 release fix – available now

Hello,

The fix for RTGI 01702 has been released. This resolves the real-time GI instability (light flicker/leakage) reported when dynamic objects moved through shadowed areas.

Please update to the latest version and restart the renderer. Let us know if the issue persists.

What is RTGI 01702? Deconstructing the Error

Before applying the fix, it is critical to understand what RTGI 01702 represents. The acronym RTGI typically stands for Runtime General Interface – a component found in several enterprise integration platforms (notably older versions of SAP Business Objects, Oracle Service Bus, and custom Microsoft Dynamics AX deployment modules). The number 01702 is a subsystem error code indicating a state mismatch between the release manifest and the target runtime environment.

In plain English: The deployment system attempted to promote a new release (e.g., version 4.2.1 to 5.0.0), but the runtime environment reported an inconsistent state. This could be due to residual files, locked registry keys, orphaned processes, or corrupted cache from a previous release.

The error often appears as:

RTGI Error 01702: Release candidate cannot be applied. Target environment in non-idempotent state. Aborting promotion.

Understanding RTGI

First, let's decode the acronym and the numbers if possible:

Phase 1: Immediate Triage (5 minutes)

  1. 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.

  2. 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.

4. Corrupted Artifact Cache

The RTGI agent caches previous releases for rollback purposes. When this cache exceeds size limits or becomes corrupted due to disk I/O errors, the release validation step fails with 01702.
