What is it?
RTX Remix for Minecraft is a beta Fabric mod that replaces the game's lighting with real-time path tracing, powered by NVIDIA RTX Remix. It targets Minecraft Java Edition 1.21.1 on Windows and requires a GeForce RTX 30-series or newer GPU. Light bounces off surfaces, through glass and from torches, so shadows, reflections and colour bleeding are computed rather than baked in.
Lighting adapts to time of day, weather and underwater conditions, and map authors can attach a specific look to locations in a world. The mod adds a Copper Beacon block whose beam acts as a real light source, supports recorded camera flythroughs for video or before-and-after comparisons, and provides an in-game settings screen for distances, framerate, sky, exposure and materials.
The mod was tuned against a showcase world built by BlockWorks, and it is optionally distributed with an NVIDIA-made LabPBR-style texture pack. Other mods, full playthroughs and newer Minecraft versions have had limited testing. The release includes an installer that sets up Java 21, Fabric and the RTX Remix runtime.
