SM didn't do that much about the regular lights at all. Every light set I've created in pre-8 versions work well in P8, every light set I've created in P8, works well in previous versions.

As long as you don't use IDL you don't have to do anything differently. My cars still look nice and shiny without IDL, using 'old' light sets or 'old' light techniques. I'm not using P4 or P5 techniques, those are already outdated since P6. But everything I've been doing since P6 still works fine...... even better!"....end Quote..

I beg to differ, there are significant differences in the look of scenes even without IDL.  There are more features with each light..  I am now able to think like a photographer when I am lighting a scene..!   IMHO most lightsets do not work as well in P8,  but by looking through the shadow light cams and tweaking then re-saving they are generally OK.
