Most humans have hair, its a pretty darned common thing. It's also one of the hardest things to make as an artist. Most humans also have roughly the same size and shape of head, so i'd say this sort of thing is fairly interchangeable I'm struggling to find any though. As far as i'm aware there's two main methods for this. One involves using partial alpha textures and lots of mesh faces, to achieve a fairly realistic hair look, and the other is carefully sculpted meshwork for a more stylised appearance. Here's a good example of the latter I especially like the ones on the bottom, and lower right. These are all taken from Dota 2. No alpha textures are involved, this is pure modelling, most likely done in Zbrush, and then with the polycount and textures heavily reduced to fit into reasonable limits. I want this, and i don't have the talent to make it (without investing a lot of time). I'm certain i'm not the first. So is anyone aware of some sample assets i could use for prototyping and modifying, or somewhere which sells this kind of thing? Premade models are a huge business, there's got to be a big market for this.
