Ok - I bought this and it worked fine on my Mac Pro for version 4.8.3. On the upgraded version it basically destroyed my first person player character as it automatically started attaching FX to the player character which in essence destroyed it for all levels and versions. So if you’re on a Mac - beware - this is not for you until he actually tests it and from our emails, he has no interest in working out the bugs on a Mac. So basically two weeks worth of work and 7 levels are toast as I try to scrub all instances of this FX out of my project. Simply replacing and merging the FP Character does not work - the FX still shows up in the script buried deep someplace in the project. Pretty disappointed.
