Some changes are made, Okay the saddle needed more gloss, it works with a normal map for the seams and not with a displacement. But when you are far away you can't see the structure unfortunately.
More interesting: I tried to fix the rigify skeleton. There are known bugs like the eyes are parented to one ear. The bigger problem was that the legs crossed in front and when I "fixed" forward kinematics, the inverse one would not work and the other way round. At the end I managed some "in between" version. This took a lot of time ... I threw out a lot of bones I don't need for the hair. Then I created a few bones to bare the teeth and I added the last "asset", a tongue.
A special particle system without children was added for eyelashes and the particle system for the mane now also creates some additional hair direct in the hoof region. I did another picture with the horse doing a natural trot, where normally two feet are on the ground.
https://en.wikipedia.org/wiki/TrotTo show at least a little bit of the possibilities of the horse-face, I added two further pictures, Here are two examples with the horse eating an apple and using the tongue (I can remember this feeling when I was approx twelve years old
). The ears, nostrils, lips, eyes and tongue are animated by bones. Closing the eyes is done by shape key. I know that this isn't 100% correct because of the linear movement, but it works.
Now I guess I've to buy a bucket of carrots to pay the real Sostado for being a model ...
