The idea: a skeleton with many bones that works with mixamo.
mixamo does not support rigified character.
but i didn't want to miss the details in the face, and i didn't want to miss the hips.
my solution: I created a skeleton with MPFB suitable for mixamo, next to it I created a rigified skeleton.
I then copied the hips and the bones in the face from the 2 skeletons.
my character with 171 bones is taken over by mixamo, and i can use any animation.
since i am certainly not the only one with such a wish, i make my skeleton available to you, the skeleton is adapted to a neutral, unmodified human.
p.s. excuse my bad english, i can read it well, but writing without a translator usually goes wrong

since the old posting is suddenly no longer to be found, i have posted it again. this time with an update so that the bones work with the mesh
