Mecanim generic rig setup.
PBR materials.
LOD version included

There is 3 different armors included: Light Armor, Poor Armor and Hell Knights Armor.

I recommend you use two sided shader in all Hell Horse materials. Unfortunately I can't include it in the pack due to Unity versions capability rules. But is really simple to make one. Here you can find instructions how to make it during 2 minutes.
