Hi there. Using Motive 1.9.0 (64bit). I'm exporting to binary .FBX and open the animations either in MotionBuilder or straight to Unity3D.

This works fine for my mocap recordings fine when using a "complete" markerset (i.e. :"Baseline + Hinged Toe + Fingers").

Today I was looking to record some upper-body-only animations, and tried the "Upper Body + Fingers" markerset, so I wouldn't have to put on the pants & shoes.
However, importing animations recorded with this markerset into any other software results in animations where every frame is like the first - not the slightest movement.

I assume it is somehow related to the missing information for lower-body bones?
Is this expected behavior?

Hello jan,

I am also using Motive 1.9 Final 64bit, and I just tested this workflow.
I created an Upper Body + Fingers skeleton, Reconstructed the take, then exported an FBX Binary.
When I open the FBX in MotionBuilder, my upper body skeleton is fully animated.

This functionality seems to be working correctly. If you would like us to troubleshoot with you, please feel free to share one of your .tak files with us at help.naturalpoint.com

Cheers,
Steven
