Thank you Ockham, you're a real gem :) I wonder if perhaps taking advantage of the script-within-a-preset trick might work here? Save a blank light set that calls a light-creating Python script to do the actual placing of lights in the scene. No way for Poser to screw that up (fingers crossed). Connatic: Unfortunately, I need soft shadows. I agree with you about the shadowcams being unwieldy, but since I use them only when I need soft shadows, they don't really consume a lot of resources. I am actually glad that Poser's raytrace lights don't support soft shadows, because that would require a humongous amount of resources.
