This is the Java part of the Radiance mod. For C++ part, please refer to Minecraft Vulkan Renderer (MCVR)

Radiance

Radiance is a Minecraft mod that completely replace the vanilla OpenGL renderer with our Vulkan C++ renderer, which supports high performance rendering and hardware-accelerated ray tracing. Due to the variety of C++ usage in the modern industrial rendering pipeline, a seamless integration of a modern industrial rendering module (such as DLSS and FSR) into our Vulkan C++ renderer is thus possible.

PBR Texture Packs

Starting from 0.1.4, no pre-processing is necessary. Load directly!

Although there are already internal emission textures, it is still recommended to use a PBR texture pack for better experience.

Installation Guide

We assume that the Minecraft base is installed in .minecraft folder. If the installation folder is different, please replace the corresponding part yourself.

Download and install .jar as usual

Download and install the mod jar to the .minecraft/mods folder as usual.

(Windows Fix) Adjust JDK's runtime libraries

Due to a known MSVC issue, some libraries from JDK itself may cause a crash.

In those circumstances, one possible solution could be:

First, try to manipulate (rename, delete, etc.) the msvcp140.dll, vcruntime140.dll and vcruntime140_1.dll in the JDK's bin folder (${PATH_TO_JDK}/bin) so that these files do not exist in that folder. This step aims to remove the JDK's dependency on those libraries.

Then, install the latest Microsoft Visual C++ Redistributable, with version Latest supported v14 (for Visual Studio 2017–2026). This step let JDK depends on the latest system libraries.

Download and install DLSS runtime libraries

To respect and comply with NVIDIA DLSS SDK licensing terms, this project and its releases do not include or redistribute any NVIDIA DLSS binaries or SDK components (e.g., nvngx_dlss.dll), and we do not auto-download them at runtime. If you want to enable the DLSS denoising / upscaling module in this mod, you must follow the download instructions below and obtain the appropriate DLSS runtime library yourself from official NVIDIA DLSS repository and place it at .minecraft/radiance folder.

By downloading, installing, or using the NVIDIA DLSS runtime library (e.g., nvngx_dlss.dll), you acknowledge that you have read and agree to comply with the NVIDIA DLSS SDK License Agreement. If you do not agree to the License Agreement, do not download, install, or use the runtime libraries, and use alternative options provided by this mod instead (after the first alpha version).

Currently, if the DLSS runtime libraries are not found, the mod will cause a crash. After the first alpha version, DLSS will be disabled and fall back to alternative implementations.

Download Instructions

Note for AMD Users: If the DLSS runtime is missing, download the DLSS runtime libraries or create a dummy empty file with the same filename to bypass the startup check. This will be fixed in the next update.

Windows

Download the files listed below from here to the .minecraft/radiance folder (if the folder not exist, create one).

• nvngx_dlss.dll
• nvngx_dlssd.dll

Linux

Download the files listed below from here to the .minecraft/radiance folder (if the folder not exist, create one).

• libnvidia-ngx-dlss.so.310.5.3
• libnvidia-ngx-dlssd.so.310.5.3

Build

First, compile Java with gradle to generate the JNI native headers.

./gradlew compileJava

Then, clone the Minecraft Vulkan Renderer (MCVR) repository.

git clone https://github.com/Minecraft-Radiance/MCVR.git

Use cmake to build it and install it. Please refer to this for detail.

Finally, build with ./gradlew build.
