Fluidloggable
Fluidloggable lets vanilla blocks hold water and other fluids in the same space as their solid form, and it also covers some functional blocks.
What it does
Blocks that a player places in a flooded area can keep water inside them, which is the core behaviour of the mod. Water is handled with realistic logic, so a fluid stays in a block and flows the way players expect. Some functional blocks, such as the piston arm, also work with fluids, which opens up a range of mechanisms that combine water with redstone.
The mod is a fork extension of the Fluidlogged mod, which first made vanilla blocks fluidloggable. Its own fluidloggable tag is empty by default, so other mods can add their blocks to it and gain support. Cloth Config API, Mod Menu and YetAnotherConfigLib (YACL) are required, and Sodium is an optional addition. Fluidloggable is client and server, so the server and every player need it, and it is released under the MIT License as open source.
Files exist for Fabric and NeoForge, covering 1.21.1, 26.2 and 26.3. The latest Fabric file is 3.1.3-beta.2-mc26.3 for 26.3, and the latest NeoForge file is 2.0.1-beta.8 for 1.21.1. Both are in the beta channel, and the author notes that some beta bugs still occur.
Key features
Fluid-holding blocks
Ordinary building blocks can hold water in their space, so a placed block sits inside a flooded area without the water being displaced.
Realistic water logic
Fluids in blocks follow a logic that mirrors how water behaves, keeping the look and flow consistent.
Functional blocks with fluid
Functional blocks such as the piston arm can work with fluid, which allows mechanisms that mix water with redstone.
Custom fluidloggable tag
An empty fluidloggable tag lets other mods add their own blocks to the list of fluid-holding blocks.

Who it’s for: Builders who work in water and players who enjoy redstone contraptions with fluid. Server owners who run modded packs can add the mod to the server with the client.
