@ThunderStone LuxRender basically takes the place of the FireFly renderer in your workflow.

Camera placement, lighting, posing your characters and props are done same as always in Poser.

When you're satisfied with your scene composition, that is where you run Pose2Lux:

• Use the materials tab to replace the Poser mats with comparable LuxRender mats.
• Use the light tab to assign the lights in your scene to groups, if it's an outdoor scene convert 1 of your infinite lights to a sun/sky light.
• Use the emitters tab to make sure that there are no unintended parts of your figures emitting light.
• Finally use the export tab to export your scene to a .lxs file for LuxRender to use.
