Or... ...you can always load up Poser with a standard or your choice of light set... Now save that blank scene with the light set of your choice as a .PZ3 or whatever version of Poser you are running... Now open your old saved data for your project in a word program (like Microsoft Word) and open the new .PZ3 (or format that you saved in) and cut the lines of code about the light set from the newly saved .PZ3 and paste it into your project that got FUBARed in the area where the code should be. Now save your updated project .PZ3 (or whatever format) with the new lines of code you just pasted into it and load the scene back up in Poser... TADA!! The Project .PZ3 (or whatever format) is usable again!! Save multiple copies of the repaired .PZ3 and your are good to go. It's a pain in the butt, but sometimes worth it if your scene has taken forever to create and don't want to have to redo everything! Hope that helps! Jack
