About this Mod
Radiance
Important: This modrinth project contains only Linux versions of Radiance. For Windows versions, please view this modrinth project.
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.

System Requirements
Operating System: Windows 10/11 (64-bit)
Graphics API: Vulkan-compatible GPU with VK_KHR_ray_tracing_pipeline extension
Hardware: GPU with VK_KHR_ray_tracing_pipeline extension (NVIDIA RTX Series or AMD/Intel cards supporting this extension)
Installation Guide

Does Radiance (Linux) need to be installed on the Minecraft server?
No. Modrinth marks Radiance (Linux) as unsupported on the server side. Install it only in your local Minecraft mods folder. Your server can remain unchanged unless the mod page lists an additional dependency.
Which version and loader does Radiance (Linux) require?
Use a file for fabric and your exact Minecraft version. Supported versions include 1.21.4. Files for different loaders are not interchangeable.
Radiance (Linux) is not working – what should I check?
First check the Minecraft version, loader version and required dependencies. Put the .jar file in your local .minecraft/mods folder and remove older duplicates. Because this mod is client-side, adding server RAM will not fix it.
