Which character do you use? If it's the Real Skin Shader I have, it is made for the Generation 3 figures and will give you warnings when you load some with unexpected texture names. It will generally still work though.

Also.. I sometimes get the "white pixel" thing in Poser 7 on some renders. I can't figure the cause out. Normally, rendering the thing again eliminates them - or moves them to another spot so I can blend the two renders. But I don't know why they're there. And why they aren't CONSISTANTLY there. I'd just written it off as a "Poser Quirk™"

When you say "blemishes" is that the AO smudging you mean or something else? A picture of it would be helpful :)

You just can't put the words "Poserites" and "happy" in the same sentence - didn't you know that? LaurieA
