ockham-- Sorry it took so long to get back to you. I tried your script, with mixed results. The script isn't too bad actually given the limitations of poser python. But I was unable to get the desired results. In a lightset I was testing there were about 15-20 OFF lights, after running the script there were 17. So, to say it worked would be wrong in my case. I am not sure what else to do about my situation other than craking open the files myself and removing them. The reason I am in such need to remove these lights is the now infamous P4 targetted spotlight problem in P5...it barfs and won't render... Oh well.... perhaps I will take another crack at the script. It sure would be nice if they could expose more of the POM (poser object model). PoserPython could be VERY powerful then ;-) Thanks again for your time
