Fluidlogged
by Leximon
Fluidlogged lets any block take any fluid as waterlogging, and lets fluids pass through blocks, without using blockstates.
What it does
Normally only a few block types can hold water. With Fluidlogged installed, a block can be filled with a fluid while keeping its own shape and contents, and fluids can flow through solid blocks. The mod stores fluids apart from each chunk's blockstates, which keeps startup time and memory use lower when many mods are loaded together.
Many blocks that cannot be waterlogged in vanilla are fluidlogged by default. Passing fluids and other features can be switched off in the config, and config changes take effect immediately in an existing world. The /setfluid command places a fluid into any block without editing the config. The mod touches chunk saving and loading, so the author asks that compatibility problems with other mods be reported to Fluidlogged rather than to the other mod.
Installation requires Fabric API and YetAnotherConfigLib (YACL) on Fabric. Fluidlogged is published for Fabric and Forge across 9 release versions, 1.18 – 1.20.1, and is released under the MIT License, so it is open source. Both sides need the mod, and the latest file for each loader is 2.0.1-beta.2 for 1.20.1.
Key features
Any block, any fluid
Nearly any block can hold any fluid as waterlogging, so builders are not limited to vanilla water-holding blocks.
Fluid passing through blocks
Fluids can move through certain blocks, which changes how water and lava flow in built structures.
Config toggles
Fluid passing and other behavior can be disabled in the config, and changes apply immediately to a running world.
The /setfluid command
The command places a chosen fluid into a targeted block directly, without any config edit.

Use cases
Decorative water builds
Aquariums, flooded ruins and underwater rooms can use fluid-filled blocks that keep their normal appearance.
Who it’s for: Builders and server owners who want fluid-filled blocks in worlds that run many mods, and who can accept the optional fluid-passing behavior or disable it.
How it compares
Water Walking Fix is client and server, open source under the MIT License, and covers 1.18.2 – 1.20.1 on Fabric and Quilt. Fluid Skills is client and server, open source under the MIT License, and runs on Fabric and Forge for 1.18.2 – 1.19.2. Fluidlogged covers Fabric and Forge across 1.18 – 1.20.1, so it reaches earlier releases than either of them.

What the author says
This description is only for version 2.0.0 and above. The old description can be found here. This is because the newer versions work completely different! This mod allows literally any block to be waterloggable with any fluid and also allows them to pass through blocks. This done by separating fluids from all…
