hey,i just recently upgraded from sp2 to sp4, everything works great in sp4, except that all my files form sp2, when i load them, it first tells me that it was made in a previous version, and if i want to update the settings (which is normal)but the problem is, whether i choose YES or NO, my render settings are messed up and don't render like before. For example the global illumination is no longer on.any idea why?again this only happens to my files that were madei n sp2, everything is perfectly fine with stuff i made in sp4.please helpthanks!
