@Riot can you please answer this?

What software/hardware do you use for making champion models and splash arts? Im trying to create a full relaunch for Evelynn (mainly lore & visuals, with w and r changing majorly, q & e changing less, and better passive for her playstyle) and one for urgot (passive & r change) Im just trying to make your guy's job a bit easier, and id really love it if you could answer ;_;
