" does it go through the body parts looking for the leading l/r or not?" No, it doesn't do anything fancy. I just set up a list of midline parts: (Hip, Abdomen, Chest, Neck, Head, Eyes) and go through each, switching the sign of Y and Z rots. The swapping of upper and lower limbs is done by a Poser internal command, exactly the same as the menu commands to swap arms and swap legs. I didn't know there was such a thing as "leading Left" or "leading Right"... Do you mean just the side closest to the camera (greatest Z value)? Or is this a specific concept? On lighting: There are several different light-changer scripts around; I think some of them (like the expensive Environment Creator by PCBos) do what you want. You might look at the recent free script by MungoPark also.
