Reality, I just tried applying the Gorilla MAT to the ball, but it just crashed my machine... Eric, I'll try reinstalling everything as you suggested, but I don't really understand your lines of code... how do I 'open up' the MAT file? Do I need special software for this? Will it work on a Mac? I know I don't have the ProPack, but the files I bought come in 2 versions PP and P4; it's easy to tell which is which, so I know I'm not trying to load the wrong ones.
