Ori and the Blind Forest: Definitive Edition - Native HDR Mod

[mqhaji]

THIS MOD IS A WORK IN PROGRESS

Summary

This mod adds native HDR support to Ori and the Blind Forest: Definitive Edition using RenoDX. The original game does not support HDR and is built around 8-bit UNORM color precision. This mod upgrades the rendering pipeline to support 16-bit float targets, implements HDR output, and applies manual fixes to resolve color artifacts and preserve artistic intent.

Features

Tone Mapping

• Vanilla – Original game tonemapping behavior (clamping to SDR).
• None – No display mapping, unclamped peak nits.
• Exponential Rolloff – Roll off peak nits by channel.
• Peak Brightness – Adjust max display luminance.
• Game Brightness – Scaling for scene output intensity.
• UI Brightness – Independent HUD/UI brightness control.

Color Grading Controls

(Enabled when not using Vanilla tone mapper)

• Exposure
• Highlights
• Shadows
• Contrast
• Saturation
• Blowout
• Color Grade Strength – Controls overall color grading strength.
• Color Grade Scaling – Corrects black levels when there is a black floor offset.

Resource Enhancements

• Upgrades the swapchain and many intermediate render targets from RGBA8 UNORM to RGBA16 FLOAT, unlocking full HDR rendering.
• Auto-detects and applies Peak Brightness based on display capabilities.

Artifact Fixes

Ori was originally built on a heavily clamped, 8-bit SDR pipeline. When upgrading to 16-bit float render targets for HDR, the game began exhibiting rendering artifacts.

These issues were resolved by manually identifying and clamping many problematic shaders with saturate().

Installation

1. Install Reshade 6.5.1 or later with addon support (no Reshade effects required).
2. Copy renodx-ori1definitive.addon32 into the Ori and the Blind Forest installation directory (same location as the game executable).
3. Launch the game with HDR enabled in Windows and fullscreen set to off in game settings.
4. Press <HOME> to open the ReShade UI and access the RenoDX tab.

im not implying anything, but it's way worse than just using autohdr. at least on my monitor

So this mod is fantastic and funtions great. But it also is stopping the game from starting up correctly to the point where I have to delete the files (and reshade files) out of the game's folder, start up vanilla, close, restore those files (but w out the reshade .log and .ini files), and then restart the game with this mod working correctly. A pain in the ass for sure, but on my LG B2 OLED TV this sure makes Ori look proper with the deep blacks levels you'd expect on an OLED display. Thanks for your labor my friend!

Renaming dxgi.dll to d3d11.dll seems to work.
