Models don't look right

[RandomRedMage]

Well first thing I think you need to do, is give real examples and maybe post a couple of screenshots to show what the actual result looks like. If your using blender and poser, I dunno much on helping you, my primary 3d experience is in PMDE, and Metesequoia. Because most of what I do is rip, rig and use in MikuMikuDance. But to get some real help, why not give us some info.

What model are you're using.
What version of Blender/Poser you're using.
