Big Mouth was the first enemy we finalized for Callisto Protocol. It went through several iterations by concept and character teams, starting with Elias Ravenetti and Taibing Zhang , and ultimately we landed on this version, a collaboration initially concepted by Jesse Lee and modelled/finished by myself.
There is another post where I share all the experiments me and Jesse did around the first enemy and Big Mouth per say. Great collaboration between different teams and this is the part I love about making games, working together.
Taibin Zheng did the final textures and material tweaks on the in-game model.
A lot of effort goes into creating these characters, from conceptual ideas, design, mechanics, animation, modeling, rigging, texturing, engineering, shaders, materials, devops, and so on. Credit goes to everybody contributing directly or indirectly to allow these models to exist.
