# Minecraft HDR Mod
\nA minecraft mod that enables native HDR on Windows\/Linux with Iris shaders. Currently, in early development.
\n![PhotonHDRPic](https:\/\/postimg.cc\/LJ7xYZvY)
\n(Photon patched to HDR w\/ Patrix, taken by mod’s screenshot feature.)
\n## What the mod have achieved
\n– Native HDR, both for Windows scRGB and HDR10\/PQ.
\n– UI color correction by a BEFORE_BLIT pass.
\n– Ingame config using Cloth Config API.
\n– Ingame HDR screenshot.
\n– Replay Mod HDR Video Export (only for versions above 1.21.10, need custom FFmpeg commandline, which can be found in config menu)
\n## For Users
\n– See XgarhontX’s temporary patches for HDR output and tonemapping on select shaderpacks with support for this mod: Google Sheets
\n – See some pics here: Wiki
\n– Adjust HDR Brightness values (Paper White, UI, Peak) with config menu. (Default keybind: F9)
\n– Take a HDR screenshot ingame. (Default keybind: F10)
\n– Supported platforms:
\n – Windows: Nvidia\/AMD GPU generally run flawlessly. Intel GPU is supported since v2.1.0 with a DXGI fallback path and there’s performance degradation (more info in v2.1.0 release note).
\n – Linux Wayland: AMD\/Intel GPU generally run flawlessly. People using Nvidia GPU may encounter some problems\/crashes, see the troubleshooting for a potential workaround.
\n – macOS: Supported but need more testing, bugs are expected. Also, shaderpack support on macOS is limited.
\n – Android\/iOS: **Not supported**. If Mobile launcher developers are interested in the project, my glfw fork can be a starting point for HDR support in the future.
\n– **Troubleshooting**:
\n – ReShade is currently not compatible under default settings, failing to load and breaking sky.
\n – Enabling “Force Activate OpenGL-DirectX Interop” in config\/advanced can improve compatibility with SpecialK and ReShade. Please make sure they only inject into DirectX 11 layer.
\n – Mods also messing with GLFW may be incompatible. (e.g. Ixeris)
\n – If your game is too bright\/dark, try to adjust the custom brightness values yourself.
\n – If you’re on Windows, don’t forget to install the latest Visual C++ Redistributable.
\n – If your game crashes on NeoForge\/Forge, disable `earlyWindowControl` in `\/config\/fml.toml`. On newer HDR Mod versions the game will crash on first launch, please relaunch the game, we’ve automatically turned off early window.
\n – If HDR is broken when shaders are enabled, please reset “Colorspace” setting in Iris\/Oculus to “sRGB”.
\n – Clean temp file if your game doesn’t start or some features are broken (path can be found in log, %TEMP%\/glfw on Windows and \/tmp\/glfw on Linux).
\n – For Linux Nvidia users, if your game can’t start, or you feel too much banding ingame, here’s a potential workaround (using Zink, so performance degradation is expected):
\n – Use these environment variables:
\n “`
\n export __GLX_VENDOR_LIBRARY_NAME=mesa
\n export __EGL_VENDOR_LIBRARY_FILENAMES=\/run\/opengl-driver\/share\/glvnd\/egl_vendor.d\/50_mesa.json
\n export MESA_LOADER_DRIVER_OVERRIDE=zink
\n export GALLIUM_DRIVER=zink
\n “`
\n – **ONLY WORKS ON Mesa >= 26.0.0**. Lower versions crash your game due to the lack of This PR, So you should probably compile by yourself.
\n## For Shader Packs
\n### Wiki Tutorial
\n– For Shaderpack Devs
\n### Macros
\n– `HDR_MOD_INSTALLED`
\n– `HDR_ENABLED`
\n### Uniforms
\n– `float HdrGameMinimumBrightness`;
\n– `float HdrGamePeakBrightness`;
\n– `float HdrGamePaperWhiteBrightness`;
\n– `float HdrUIBrightness`;<\/p>\n

Use these uniforms inside `#if HDR_MOD_INSTALLED` block.
\n### Output
\nthe output of the shader(aka. what is written to main render target in final pass) should have **scRGB-nl encoding(Rec.709 primaries, sRGB (for negative numbers use \u2212f(\u2212x)) transfer function)**, and you should not use RGBA8F for scene color.
\n– Wiki Section
\n## Known Issue
\n– Xaero Map may cause black screen on startup, but recover to normal before you see title screen.
