heyas; if it has groups in the obj, you dont need materials -- not for vue. in fact, having both in vue makes a mess, because it creates the materials as sub-groups of the groups (when a group has more than one material). for example, you MIGHT start out in poser with, say a nice figure with one big skin material over most of it, and some fingernails and eyebrows and lips here and there. then when you get it into vue, you end up with the materials scattered throughout the groups. you get stuff like head:skin, head:eyebrows, head:lips.... and then you get into junk like hand (with only skin on), pinky 1, pinky 2, and pinky3:skin pinky3:fingernails.... and then trying to apply ONE skin texture to all the skin bits lying around.... argh! :) when making an obj for vue, i usually either make one group for each material (and no materials), or one group with all the materials. if that is the way the barn appears in vue (with no tweaking of the obj), its fine. the materials for each part are all there. what's the problem? :)
