FAQ

My sponge removes one block less than vanilla

That is the default. The search size includes the sponge's own block, and the default maxCount of 64 is one lower than vanilla's 65, so a default install removes 63 blocks of water where vanilla removes 64. Set maxCount = 65 to match vanilla. See Configuration.

I raised maxCount and nothing changed

You have probably hit the depth limit. With the default maxDepth of 6, a sponge in open water reaches at most 376 blocks, so a bigger maxCount does nothing there. Raise maxDepth too. The table in Configuration shows how much each depth can reach.

My sponge does not turn wet

Check these in order:

• There is no water connected to the sponge within maxDepth blocks. Water on the other side of a wall or an air gap is not reachable.
• maxCount is set to 1. The sponge uses the only slot, so it can never remove anything. Use 2 or more.
• The block is a wet sponge already. Only a dry sponge absorbs water.

Do I need to restart after changing the config?

No. The file is watched, and a saved change applies to the next sponge. If you edit the file while the game is running, wait a moment for the save to finish before placing a sponge.

Where is the config file?

config/configurablesponge-common.toml, in the game folder for single player or the server folder for a dedicated server. Delete it to get the defaults back.

Can I have different settings per world or dimension?

No. One set of numbers applies to everything that runs on that instance.

Can a sponge absorb lava, or other blocks?

No. The mod only changes how far the search goes and how many blocks it takes in. Only water is absorbed.

Does it work with modded sponges?

Only sponge blocks that extend the vanilla sponge block and use its built-in search pick up the new numbers. A modded sponge that has its own search is not changed.

Can a big sponge lag my server?

Yes, if you set very large values. Each block removed is a block update, and the search runs on the server thread. See the warning in Configuration.

Which loaders and versions are supported?

Fabric and NeoForge for Minecraft 26.1.2. See Getting started.
