I made the lowpoly version + UVs + textures of the awesome character bust sculpted by the talented Sergey Katsukov. This model helped Akeytsu team to develop their blendshape system. Thanks to Aurélien Charrier, Serger Katsukov, Clovis Gay and Cédric Vidal-Duvernet for the nice opportunity to work with you !
Akeytsu is an animation software which redefines how you rig, how you animate, and simplify tedious and too technical tasks to let you enjoy animation like never before. It fits perfectly with Unreal Engine, Unity, and any app which supports FBX file format. I used it a lot on StarWars - Redemption, The Burning Descent VR, and all my characters/animate-able things =)
Be sure to check it out and spread the word !
Also, please note that since (now) I'm working for Nukeygara, I've took some time to explain how to rig a face nicely and 100% on Akeytsu here : https://www.nukeygara.com/blog/use-case-create-a-facial-rig (free Akeytsu rig included ;))
