Reduce texture size.I have had the same problem with Infinite and some select objects.I have never used DAZ Studio,but i do know Vue has issues with very large texture maps.I have reduced them in Poser before export and have had no problems.As for your faulty mapping,i think that maybe that is a DS problem,could be wrong but i have never had it happen to me.Vue is pretty damn smart with texture mapping i think.Good luck.
