I'm Fizzy, and I've been a member of a team since the release of the first official trailer for Pokémon Cobalt and Amethyst. That was around the beginning of May 2015, if I remember correctly.
At first, I was doing a lot of Pokémon models. I then started to spend a lot of time developing a tool that eventually allowed us to animate our models really easily.
In the end, I released the generator to the public and maintained it for quite some time, but I wasn't really happy with it so I decided to redo everything to really focus on making the program more user-friendly. You can actually check out the current version right now on github.
