when you imported the model, if you didn't chose GROUP FIGURE AS SINGLE MESH, it will be in many pieces. Personally I suggest NOT ticking this box, it brings in many pieces which can then be altered later to suit special needs, but sometimes as said, you have issues with SSS and radiosity.

sometimes it's important to have the human figure, and ONLY the human figure (no props, or clothes) as one solid object when using SSS
so what I do is:
import as many pieces,
work on materials.
save figure out as .vob

then I will weld up the Poser person only, no props or clothes, this is easier for Vue to work with and often fixes SSS problems but NOTE!!! hair and eyelashes can cause problems, I don't know why, but believe it's the transparency, sometimes you have to split the model, seperate the hair/eyelashes into another group, then weld up the rest of the model
then once all is welded and nice, save as a different named copy of the figure as a .vob like "Mike 4 welded.vob"

SSS issue maybe because each seperate part is acting as an object thus screwing up the limits of the SSS, for example, you may see dark edges around finger joints, and other areas where individual pieces meet.

also, try rendering with radiosity ON and OFF, see if that brings this issue up, I have found that it does.
