What Relumination works with.
| Platform | Java Edition |
|---|---|
| Loaders | Iris |
| Minecraft versions | 1.21, 1.21.11 |
Relumination is a lightweight vanilla-like shader pack for Java that swaps vanilla lighting for colored, directional light. Sandmuel made it for Iris and tags it potato and low, so it aims at modest hardware. Shaders load on the player's own machine only.
Shader loaders and versions
- Iris: Minecraft 1.21 to 1.21.11.
What Relumination changes
The pack is an alternative to vanilla lighting that reworks how light behaves and what color it takes. Modrinth tags also list bloom, foliage and atmosphere.
- Light intensity and color shift with sun and moon position, light level and other factors.
- Directional lighting on blocks, items and entities.
- Held item light.
How to install Relumination
- 1.Install Iris on Fabric or NeoForge for a supported release.
- 2.Place the pack's .zip file in the shaderpacks folder.
- 3.Open Video Settings, then Shader Packs, and select Relumination.
The shader install guide covers folder locations, and the shaders not working fix helps if the pack does not appear in the menu.
Trade-offs
The focus is light and its color. That narrow scope is the appeal if lighting is what you want changed, and the limit if you expect more.
Global Illumination with no tracing and no fps cost
Questions about Relumination.
4 questions
How do I install Relumination?
Install Iris, put the Relumination .zip into the shaderpacks folder, then open Video Settings and choose Shader Packs. Select Relumination from the list and apply it. The pack needs no other dependency according to its release listing.
Does Relumination work with Iris?
Yes. Iris is the only loader the pack lists, and it covers releases from 1.21 to 1.21.11. Nothing in the listing mentions OptiFine support, so plan on Iris.
Is Relumination good for low-end PCs?
Its creator describes it as a lightweight alternative to vanilla lighting and tags it potato and low. That positions it for modest hardware, but actual frame rates depend on your system, so try it and adjust.
Does Relumination work on Bedrock?
No. Relumination is a Java shader pack that depends on Iris, and Iris cannot run on Bedrock. Bedrock players need a different pack format made for that platform.
