Footprint Particles

Mobs and players that walk over soft materials such as dirt, wool and sand leave footprints. Players leave footprints only while sneaking. The footprints are particles, so they appear in the world without changing the blocks underneath them. Footprints disappear after a configured amount of time, which the author set up to keep the server from lagging with too many of them.

The mod is a data pack that adds a simple set of quality-of-life options, and it is published for Fabric, Forge and Quilt. Its settings are changed with scoreboard commands rather than a config file: a player can switch mob footprints on or off, set how long a footprint lasts, and cap how many exist at one time. Only the server needs it, and clients may skip it. Files cover 1.19.4, 1.20, 1.20.1, 1.20.2, 1.20.5 and 1.21, with 6+mod for 1.21 as the latest file on each loader.
