AnyVanillaWaterlog
AnyVanillaWaterlog lets many more blocks hold water, so underwater builds, fountains and aquariums need fewer workarounds in Forge worlds.
What it does
In vanilla Minecraft only certain blocks such as stairs, slabs and fences can be waterlogged. The mod expands that waterlogging system so a much wider set of blocks can contain water, which makes underwater structures and detailed builds simpler to construct without relying on complicated tricks.
The changes follow vanilla behavior closely and adjust how water interacts with blocks that gain support for waterlogging. The mod stays compatible with Minecraft's fluid update system, and players who see bugs or visual glitches tied to water updates are asked to file a report.
Installation requires Forge only. A server running it needs every connecting player to have it too. Files are published for 1.21.1 – 1.21.11, and the latest build, 0.5.0.0 for 1.21.11, is on the beta channel. It is released under the Apache License 2.0 and is not open source.
