b. There's really no sensible way you can animate a sculpt like this, don't remember the exact polycount but it's millions at least. You'd have to make a lowpoly and then unwrap it. This has a lowpoly base I did ..maybe in an hour or so.
What do you mean by unwrap? I don't want to bother and I'm still learning about zbrush, I understand the point of using a lowpoly base, but there is no way to make the same effect without making radicals change in the character or having some kind of pc made by nasa engineers?
btw, I trow a death horse to the goat and it survive, and worst, now is stuck and I can lift the horse again.
