Frequently asked
Does Lightmap Fixer work on Minecraft 1.21.11?
Yes. 1.21.11 is the newest Minecraft version Lightmap Fixer declares support for, and the claim comes from the author's own release metadata rather than from a compatibility list somebody maintains by hand.
Which Minecraft versions does Lightmap Fixer support?
Everything the author has declared, from 25w35a up to 1.21.11. The full list is in the table above, with the Java runtime each version needs next to it.
Do I need to install Lightmap Fixer on the client or the server?
The client only. There is nothing to install on the server, so it works on any server you can already join.
Which Java version do I need for Lightmap Fixer?
Java 21 or newer, because that is what the newest Minecraft release it supports requires. The requirement comes from the game rather than from the shader pack itself.
What licence is Lightmap Fixer under?
MIT, as stated by the author on the platform we synced it from. Check the project's own page before redistributing or bundling it.
How do I install Lightmap Fixer?
Install the matching loader first, then put the downloaded file in your mods folder and start the game. The loader, the shader pack and Minecraft all have to be on the same version, which is the usual reason a mod does not appear in game.
Where do I download Lightmap Fixer safely?
From the author's own page on Modrinth, 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.
Works on the same versions
