Same here.  That's why I'm so glad there is the free Pose2Lux exporter.  In the time it takes for me to get anything close to what I want after all the tweaking and re-rendering with Poser's Firefly, I would have already have a perfect render from LuxRender.   Check out my tutorial on how to use Pose2Lux.  I got some renders in my gallery that you can see what you can do with it.
