Mixamo animation is very good but very difficult to use in games.

I made this to use Mixamo animations in the game.

RootMotionGuide helps you use root motion animation in your game.

RootMotionMovement selects the appropriate root motion animation and interpolates to smoothly perform root motion.

And it provides a variety of tools for using Mixamo animations in the game.

RootMotionGuide moves the complex character's animation and movement logic to the map.

As a result, you can keep your character's logic simple and create a movement logic specific to a particular Map.
