This trailer is starring the Sniffler I made at Ubisoft Montpellier.
It was actually an early test to see how the character( and the 3D model) will move and act in 3D.
Even if he is transforming from a ball to a creature (as in the game) the two states can be considered as a 2 separates characters.
They are using in the same rig two specific sets of controllers / deformers.
The animation and render was made at Cube Creative.
