My musty, dusty brain remembers a lighting issue with P5 relating to light sets from previous Poser versions. I don't know whether this was resolved with some of the SR updates or not - Check the fix list for SR3. Otherwise, you might try the following: (1) Save the light set for the WIP separately to the Light library; (2) Delete them from the image WIP; (3) Save and reopen the image WIP; and (4) Add back the light set you previously saved. Or... (1) Record the settings for the light set (screen shots might be easier than writing it down); (2) Delete the lights from the image WIP; and (3) Recreate the lights manually. Good luck! -Nancy.
