I used two texture maps, one for the body of the horse (including eyes and mouth) and the other one for mane and tail

Horse sculpt I made in ZBrush, which I later used as a base for creating a low poly model; Afterwards I baked the details from high poly model onto low poly model, so I could preserve the details I sculpted, while having manageable topology

Initial concepts weren't limited to only horses, as I was exploring ideas for different creatures at that time. I settled on the horse, as this is an animal that's the closest to my heart, so I wanted to learn while making it.

Here are some of the references when sculpting. Two different types - on the right were the ones I used as guideline for what kind of horse I wanted to make; on the left there are some anatomy references I was using (there were a looot more of those).

Setup I made in Unreal for rendering - directional light together with 3 spotlights; Material setup I made uses also wireframe mask, so I could show the wireframe in quads easily, as tools that Unreal has inbuilt show a triangulated wireframe instead
