This is just a Hollywood actor generator. I want a human generator that has an age slider that melts faces like aging does in real life. I want to control fat, folds, swollen skin, grease, bald patches, moles and skin conditions. Very few people have perfect teeth. In my dream human generator you should be able to remove, rotate and reposition every single tooth.
All the marketing material of MetaHumans focuses on the head. There is probably not as much control over the rest of the body. We are probably decades away from a true human generator.
