Issue with MoCap Marker Activation on Actor

[d.reiser]

I am using .c3d motion capture data and am trying to project the animation on an actor. After setting the corresponding markers and clicking on "Active", the actor immediately switches into a sitting position and doesn't respond to any changes in the MoCap data when the frame changes. Here are some pictures for visualization: 

1.) Marker setting prior to "Active"

2.) Instant pose switch after "Active"

3.) Different perspective

4.) No response to changes in frame

Any help is greatly appreciated. It happens with any .c3d data and in MotionBuilder 2018 as well as 2016.

I have the same issue.

I often encounter the same issue when only one optical marker is assigned to the Hips cell of the Actor representation. Indeed, I successfully activated the actor in the FBX file that @d.reiser shared by adding three additional waist markers to the cell.
