Hey, I'm trying to rig my character in Mixamo, but it says 'Unknown error generating movement

place all markers means you skipped a step or the model has info Mixamo can't read... like the wrong file format

unknown error will be a non human rig... so wings or a tail for example

to be clear, you can have sword, shield, wings and tails in Mixamo but it has to be in the correct locations in order to animate

Moved from the CC Services forum to the Maximo forum.
