Hi does anyone know how the animals and wiledlife in skyrim respawn's. i wan't to make a zombie mod where zombie's roam around the world but i need to find out how the animals (like wolfs) respawn in the world.

That goes over encounters, so how they are created and spawned in the world. As far as the respawn mechanics specifically I haven't played around with them, but that'd be a good place to get started.
