Kiera... No, I installed V3 directly in my Poser 5 runtime... After posting the above message, I tried the same scene again and it worked, so not sure what happened... In fact, the post with the V3, V3toV2 comparison was the one I was trying to do.

Humankind has not woven the web of life. We are but one thread within it.
Whatever we do to the web, we do to ourselves. All things are bound together.
All things connect......Chief Seattle, 1854
