I had the same problem when I had just purchased Vicky 2.0 and her Hi res Texture maps. Basically The mat pose files that come with Vicky 2 are the mat files for Pro Pack users. Pro Pack can use Jpg files as bump map without the need to convert them. Even if you have converted the .Jpg Bump Maps In .Bum format every time you use those mat files you get that problem. You need to go to DAZ web site on the V2 texture maps product page and download the update that will install the mat files for Poser4 user that will search for the .bum maps. Hope that this will help :) Staby
