Footsteps on ground
We see on the roads permanent traces of wheels in the mud.
It would also be cool to see the footsteps of other hunters running through.

Generally, really to make the footprints disappear in the mud after 5 minutes, for example.
There are already far too many things that give away your location in the game. Adding more would hurt the game experience for most people.
