Marker placement issues

[jsonedecker]

I am looking for some direction on getting the best marker placements possible. We follow the ARENA setup wizard and get pretty good results except for the shoulders/clavs. They seem to droop once we process the motions.

I assume it's the marker placements, but maybe not? Are there any tutorials for marker placement?

This is most likely due to the placement of the top back / neck marker. It should be between the shoulder sockets, you might have it a bit high. Try changing this postion a bit, and see if that helps.

Also, you can adjust the shoulder width during setup, that can also be an issue here.
