Spreading Gravel
by edward3h
Spreading Gravel changes how gravity blocks settle, letting sand and gravel slide sideways toward the deepest nearby drop instead of falling straight down.
What it does
A gravity block placed with Spreading Gravel checks the four cardinal directions, north, east, south and west, and slides toward whichever available drop is deepest. Where no sideways drop exists, it falls straight down as vanilla gravel does, and it follows vanilla water-fall behaviour when it meets water.
The mod is open source under the Apache License 2.0 and needs Fabric API. Its files target 1.21.1 only and are published for Fabric and NeoForge; both the server and every player need it, so the environment is client and server. Public source code and an issue tracker are linked from the project.
Key features
Sideways flow
Gravity blocks slide toward the deepest nearby drop in any of the four cardinal directions, which changes how terrain is shaped.
Vanilla fall behaviour
Where no sideways drop exists, the block falls straight down, and it interacts with water in the same way as vanilla gravel.
Shapeless recipe
A shapeless recipe combines 3 gravel and 1 sand, and the recipe appears in the recipe book once the player picks up gravel.

Use cases
Terrain shaping
Players who build or reshape landscapes can use the sideways flow to move material toward a chosen pit or ravine.
Modpacks
Modpack builders can add the mod to a pack to change gravity block behaviour alongside other terrain content.
Who it’s for: Players and server owners who want gravity blocks to behave differently from vanilla, on 1.21.1 with either Fabric or NeoForge.
How it compares
Renewable Gravel and Sand is published for Fabric, Forge, NeoForge and Quilt on 1.21.7, is server required with an optional client, and is not open source. Lower Player End Gravity runs on NeoForge for 1.21.1 with the client and server environment, under the MIT License, and is not open source. Create Positional is open source under the MIT License and runs on NeoForge for 1.21.1 as a server-side only mod, so players join without installing it.

A Minecraft 1.21.1 mod that adds Spreading Gravel — a gravity block that flows sideways toward the deepest nearby drop. Spreading Gravel behaves like vanilla gravel when falling straight down. When it lands, it checks the four cardinal directions (N → E → S → W) and slides toward whichever has the deepest available…
