See those attached screenshots of the Preview window? It's usually worse than that. Every time the camera angle changes, the preview rearranges the messy portion of polygons, most of the time reaching so far as to block the view. While there's a recognizable form beneath the mess, even that form looks improperly, jaggedly shaped, as if the vertices are connecting to the wrong nearby vertices (like it were reading some kind of corrupted version of the map, except that no 24-bit sculpt map can possibly reach as far as those stray polygons!). Reproduction of the problem, by the way, is as easy as can be, and seems consistent. I've tried it on 2 different computers with 2 different sculpt maps (and received just the same erratic vector vomit displayed around my sculpties). I then tested it on an image that doesn't register as a sculpty, and thus instead becomes a sphere. Even that sphere was a mess!
