About this Mod
Fluidlogged
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!
Requires YetAnotherConfigLib and Fabric API on Fabric
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 blockstates in each chunk which solves startup time and memory usage when a lot of mods are installed.
Many non-waterloggable blocks are fluidloggable by default. If you don't like some features such as, fluids passing through blocks, you can disable this in the config. Changes to the config are applied immediately to your world!
There's also a command to place fluids in every block without updating the config:/setfluid

Can I use it in a modpack?
Feel free to use any of my mods in a modpack!

Fluidlogged server crashes on startup – what to do?

Is Fluidlogged compatible with fabric and forge?
Fluidlogged officially supports fabric, forge for Minecraft 1.20.1, 1.20, 1.19.3. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with Fluidlogged – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Fluidlogged consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
