BiolithRequired. A biome placement mod focusing on configurability and consistent distribution of modded biomes

Frequently asked

Does Wetland Whimsy work on Minecraft 1.21.1?

Yes. 1.21.1 is the newest Minecraft version Wetland Whimsy 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 Wetland Whimsy support?

Everything the author has declared, from 1.20.1 up to 1.21.1. The full list is in the table above, with the Java runtime each version needs next to it.

Do I need to install Wetland Whimsy on the client or the server?

Both. Every player needs it installed and so does the server, so anyone joining without it will be refused.

Which platform or loader does Wetland Whimsy support?

Forge, NeoForge. A build for one platform or loader will not necessarily load on another, so this is the first thing to check before the Minecraft version.

Which Java version do I need for Wetland Whimsy?

Among the supported Minecraft releases above, the highest recorded requirement is Java 21 or newer. Use the requirement for the exact Minecraft version you run; previews and snapshots may differ.

What does Wetland Whimsy need to run?

It declares Biolith as required, so that has to be installed alongside it or it will not load. Each one is linked in the dependencies section above.

How do I install Wetland Whimsy?

Install the matching loader first, then put the downloaded file in your mods folder and start the game. The loader, the mod 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 Wetland Whimsy safely?

Start with the author's page on Modrinth, which is where the data here is synced from. MCReference does not host or repackage files. When available, recorded download links go to the source for that release; verify the publisher, filename and any available checksum before running it.
