MakeHuman is for creating human mashes for use in animations, 3D renders, and games. You can adjust dozens of different phenotypical traits to customize how a 3D character looks, and then export that model to use in the 3D software of your choice. MakeHuman can export using several topologies, from low poly versions where fast performance is necessary, to high poly versions for polished renders. Similarly, you can map the model onto one of several skeletons for animation.
MakeHuman is very intuitive and easy to use. Simple sliders adjust all the human traits, and you can immediately see what effect each slider has on the finished model.
