The Freelancer scene re-rendered by loading it into DAZ Studio 4 Pro (was created in DS3A) then using Reality 2.0 to export it to Luxrender 0.9. No postwork!!
No, it imported in just fine. I think the only major change was modifying the gamma in Lux to give it more contrast (most obvious on her face). I think this was a case where the changes in Reality and Luxrender all worked in my favor!
