Sounds like there is some issues with the mapping, but if they render ok in Poser, it can't be too wonkie. I've had this happen before with a few LWO models, so to fix them I opened the models in another app (Modo) and exported them as OBJ files which miraculously fixed the mapping scale issues.

I'd be curious to see what would happen if you exported the model from Poser as an OBJ or something to see if that helped to correct things when bringing it into Vue as otherwise you're probably going to have to go into the material editor and tweak the scale of the maps manually until they start to look right.
