Enable Pathways for Mobs
By default, Once Upon A Stroll only creates footpaths when players walk across grass. If you want mobs to also leave trails as they move through your world, you'll need to adjust the mod's configuration.
Access the Config File
Locate the mod's configuration file in your .minecraft/config folder. Look for the Once Upon A Stroll settings file.
Enable Mob Pathways
Find the option that controls whether mobs create paths (typically labeled as something like "mobs enabled" or "paths for mobs"). Change this setting from false to true.
You can also adjust the weighting value for mobs if you want to control how frequently their footsteps create visible terrain changes. A higher weight means paths appear more often.
Reload Your World
Save the configuration file and reload your world. Mobs like sheep, cows, and other creatures will now leave dirt trails as they wander through grass terrain. Be aware that enabling this feature on heavily populated areas may impact performance, so monitor your frame rate if you notice lag.
