About This Mod
This mod utilizes the ReShade Add-on system to streamline updates and avoid direct game file modifications. The source code is available on GitHub for those interested in seeing the inner workings or contributing to future improvements.
Original HDR Issues:
- Broken Displaymapping: The game's final color grading LUT seems to apply tonemapping to a fixed peak that is much lower than 10,000 nits. The displaymapping at the end then tries to tonemap down highlights on an image with already significantly reduced highlights. The end result is highlights that undershoot massively on higher nit displays.
- Broken Brightness Slider Behavior: The game's brightness controls apply before the final tonemapping/grading LUT. This results in broken contrast/hues/saturation depending on what value you set the slider to.
- Mismatched EOTF Handling: The developers encode the image with sRGB gamma. This doesn't match what the vast majority of displays are calibrated to, which is 2.2 gamma. This results in the developers seeing a much more contrasty image in SDR when developing the game, that doesn't match how it looks in HDR. The SDR calibration menu also seems to imply a 2.2 gamma display is expected. The Rec.709 option also doesn't make sense as the spec says to pair it with 2.4 gamma. Which has a way more contrasty look than sRGB paired with 2.2.
The Solution:
- Fixed Tonemapping: Before displaymapping, peak brightness is boosted to pre-tonemapping levels, so that the display mapper can then map them properly to the expected peak. Peak brightness now behaves as expected and does not undershoot.
- Fixed Brightnesss Slider Behavior: The brightness slider has been adjusted to apply after tonemapping. This keeps contrast/hues/saturation more consistent.
- EOTF Emulation: sRGB -> 2.2 gamma EOTF emulation has now been applied to the image, matching how the developers likely saw the image as they were developing the game.
- Enhanced User Control: Introduces interactive sliders for players to customize their visual experience to their liking, ensuring a more balanced and visually pleasing HDR presentation.
In the ReShade UI, you'll find a RenoDX window with options to customize your HDR experience:
- Tone Map Type: Choices include Vanilla and RenoDX.
- Peak and Game Brightness
- SDR EOTF Emulation: Choices include Off, 2.2 (Per Channel), and 2.2 (By Luminosity).
- UI Brightness
- UI Visibility
- Color Grading: Exposure, Gamma, Highlights, Shadows, Contrast, Saturation, Highlight Saturation, Dechroma, Flare.
- Effects: Noise, Vanilla Film Grain, Custom Film Grain
Installation
- Copy the `dinput8.dll` file from the RE9 build of REFramework's latest nightly into the Resident Evil Requiem installation folder next to the game exe.
- Install ReShade 6.7.2 or higher with addon support. No ReShade effects are required.
- Copy the `renodx-re9requiem.addon64` file into the Resident Evil Requiem installation folder next to the game exe.
- Run the game and access the ReShade UI with <Home>. Select the Add-ons tab and disable `Generic Depth` and `Effect Runtime Sync`, then restart.
- Run the game and access the ReShade UI once again. Now you can navigate to the RenoDX tab and adjust the settings to your liking.
- Settings in the Tone Mapper section do not apply in real time and require the user to toggle HDR off and on again in order to apply in full
