Another thing to consider with all this tiny detail.... Detail is great, but with the pull back of the camera and the more than likely full shot you are going to have of the horse, are you going to be able to see all this detail?? Do a test . If it's a close up then fair enough, I'm just a slave to TV Production, and this is one of the first things I ask of myself before I spend the time. Maybe your time could be spent on other more important detail. Displacement is fine, but your more than likely going to pull your own hair out by the time you've finished your test renders! Just something to consider because I know that getting pulled into the detail can get you lost in time and perspective and when all is done and the detail cannot be seen it's a bummer! Check my thread for the paintfx derections I used on Gandalf.
