VoxelFall
by oqogxa
VoxelFall applies basic block physics, so loose blocks like sand and gravel fall in a more natural way instead of staying static.
What it does
Unsupported blocks drop and settle with a smooth motion rather than staying fixed in place. Sand and gravel are excluded from this behavior, so their vanilla placement rules still apply. The aim is to make the world react to changes a player makes, without restyling the game more than necessary.
The mod is built for players who want small gameplay details that make a world feel alive while keeping the vanilla look. It is a Fabric mod for 1.21.6 – 1.21.8 that needs both the server and the player to run it, and it lists Fabric API as a dependency for survival play. The author describes the project as in alpha, so bugs and unexpected block interactions may appear, with updates and fixes planned as development continues. The code is not open source, and All rights reserved applies.
Key features
Smooth falling blocks
Blocks without support slide down over a short motion instead of disappearing or stopping in mid-air.
Sand and gravel excluded
Sand and gravel keep their standard behavior, so the mod changes only the blocks it targets.
Basic physics layer
The mod adds a simple physics layer that reacts to block removal, extending survival play with a further detail.
Realistic settling
Blocks settle into place after falling, giving builds and terrain a more immersive appearance.

Use cases
Survival worlds
Players who want the world to respond to digging and building can use VoxelFall in a survival world for added immersion.
Multiplayer servers
Server owners can run the mod so that block behavior matches on every connected client.
Who it’s for: Players who want realistic small details in a vanilla-style world, and server owners who want the same block behavior for everyone who joins.
How it compares
Sand and gravel are forbidden to fall is a Fabric mod for 1.20.1 that is client and server and under the MIT License, but it is not open source and targets a different version. Sand Dust is a Fabric mod for 1.17.1 that is client and server and open source under the MIT License. Resounding is client-side only and open source under the GNU Lesser General Public License v3.0 only, for 1.18.1 – 1.19.2. VoxelFall is client and server and covers 1.21.6 – 1.21.8, so it does not overlap with those version ranges.
