Some time ago I also had a problem over there. Mine was with a texture that didn't fit where body and head meet in the neck. It was obvious and clearly visible. After many, many weeks, the artist had been contacted and repaired the problem. But it looked like as if nothing had been done. I compared in photoshop, and the neck hadn't even been touched. I mailed Daz and got an answer back that my standards were very high blahblah and that I could get a refund. And that the item would be removed from the store. The refund was only part of what I paid, and the item is still for sale. Moral of this story: don't expect much help or support. Here at R. you can contact the artist yourself. Over there, they do it for you. As for your item: the P horse is a completely different mesh, so all fitting will have to be done in a 3D app. My guess is that if there are enough people asking for it, it might become commercially interesting to create and sell one. Yet, perhaps there is some good soul who created one in freestuff somewhere?

I have tried prudent planning long enough. From now I'll be mad. (Rumi)
