Once I had the main Poké Ball done I wanted to do some of the others from the games and anime. There are 26 Poké Balls from the games and I added 10 from the anime. For most of them all I needed to do was change the texture of it, some others I had to add additional meshes like the Heavy Ball and Master Ball. The Cherish Ball was completely different had to rework the meshes to get the correct look of it.
You forgot 2. The old pokeball used by sammy oak in the celebi movie, and the dark ball also used in the celebi movie. Also wasn't there a special ball used by the little girl in the entei and unown movie?
