First, amazing work Kevin.
I'm afraid there is something wrong with the Male animations in this package.
I'm setting up the rigs as Humanoid in unity 2022.3.25. First I can successfully generate the avatar for the male HumanM_Model. Then when I set Humanoid rigs for the male animations I get this error: Avatar Rig Conifguration miss-match. Transform hierarchy does not match (full details in the screenshot).
Note that It works for the female animations, but fails for ALL the male ones.
I've repeated the process several times, deleting and reimporting the assets again, but I always get the same error.
Again thank you for your work
