Lovatto Studio

Do you also have the problem with animation?

It's not an error nor problem, like I said before, that movement is due to the Run animation,
I'll say the same again because I just checked that it works, you simply have to replace the Sprint/Run animation of the Player Animator Controller in both layers: Body and Upper Body, but the most important is the Body Layer -> Stand -> Move -> Blend Tree -> change the run/sprint animation there.

Could you do me a favor and send me the player that works?

I have now tested it with 3 run animations, it always comes out the same.

I would be very grateful.
