RenoDX - HDR Black Floor - Tonemap - PQ - LUT fix for Resident Evil 7 (DX12 RT only)

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 Tonemapping: The default tonemapping doesn't account for user brightness causing over/undershooting of peak whites depending on how high the paper white slider (2nd slider in calibration menu) is set[/]

  []Poor LUT Sampling: The game uses sRGB LUTs that only accept an SDR input. In order to get this working in HDR, the developers created a piecewise function that crams all the highlights back into SDR range and then multiplies them back out afterwards. This causes a loss of detail in highlights and broken gradients.[/]

  []Gamma/Contrast Boosts: The developers added a gamma/contrast boost to the image that is not present in SDR. This boost was seemingly an incorrect attempt at fixing broken gamma in HDR as they used sRGB gamma in SDR but likely calibrated the game on standard 2. 2 gamma displays. The SDR calibration menu also seems to imply a 2. 2 gamma display is expected[/]

  []NVIDIA Driver Bug: The NVIDIA driver often glitches out and forgets to set the color space to HDR10, causing the image to be interpreted as the wrong color space and become washed out.[/]

• []Refined Tonemapping: Implements a Vanilla+ tonemapper that corrects peak white levels and removes unnecessary contrast/gamma boosts.[/]

  []Enhanced HDR LUT Sampling: Highlights are now first tonemapped down properly to SDR, and a new function is used to calculate the change in color from the LUTs, which is then applied to the original HDR color. Gradients are now fixed, colors are now more vibrant, and incorrect hue shifts are now eliminated.[/]

  []True to Source Visuals: sRGB -> 2. 2 gamma correction has now been applied to the image, matching how the developers likely intended for the game to look.[/]

  []Force HDR10 Color Space: When the addon detects that HDR is enabled, it forces the HDR10 color space, fixing the washed out bug.[/]

• []Sharpening: The vanilla overly strong sharpening has been replaced with Lilium's RCAS sharpening.[/]

  Installation 

  • []Install ReShade 6. 7. 3 or higher with addon support. No ReShade effects are required.[/]

    []Copy the `renodx-re7-2r-3r-village.addon64` file into the game's 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.[/]
