R-T-SMinecraft shader pack

What is the R-T-S Shader? It is a shader pack that attempts to simulate complex global illumination techniques. Unlike traditional shaders that rely on simple rasterization, R-T-S calculates light paths more realistically within the game engine.

Frequently asked

How do I install R-T-S?

You need a shader loader first: Iris (with Sodium) or OptiFine. Put the downloaded file in your shaderpacks folder and select it in the video settings shader screen. The shader loader, not the pack, decides which Minecraft versions work.

Where do I download R-T-S safely?

From the author's own page on CurseForge, which is where the data here is synced from. MCReference never mirrors, re-hosts or repackages a file: every download button points at the original source, so you get exactly what the author published.

Which Minecraft versions does R-T-S work on?

The author has not declared a supported version in the metadata we sync, so there is nothing here we can state as fact. Check the project's own page before installing it, and treat an old shader pack with no declared version as untested on modern Minecraft.

Last checked 20 d ago against CurseForge. We do not host files and we do not republish descriptions; every download link points at the author’s own release.
