In this pack, you get not one, but three FBX models! First is a low-poly with handmade retopology. The second is a decimated mid-poly model. And the third is the original asymmetrycal sculpted mesh with high poly density, just in case if you need it.
First two game-ready models include almost all anatomic structures, with a few removed to reduce the poly count. But the third one is truly anatomically correct.
