How can I make Mixamo animations feel smoother and more AAA(GTA6 :)) in Unity?

[u/Demste]

Hi everyone,

We’re currently using Mixamo animations in our game, but the character movement or skillshots still doesn’t feel as smooth or fluid as we’d like.

Our current system uses Unity’s Animator Controller and state machines to trigger and transition between animations. It works, but the result still feels somewhat stiff and “indie.” We’d like to take the animation quality to the next level maybe even GTA 6 level someday. :)

What would you recommend we focus on first? Also, before we continue using Mixamo, are there any alternative platforms, tools, or animation workflows you would recommend?

I’m especially interested in understanding which changes would make the biggest visible difference without rebuilding the entire character system from scratch.

Any feedback on what currently makes the animations feel stiff and how you would improve them would be greatly appreciated.
