How can I stream or export the markers to Motion Builder without using the the skeleton?

Are you just looking to export individual markers?

Would like to export the markers that were originally captured. Not the ones, that the skeleton reinterprets. They are displayed but I could not find a way to export them.

It is not possible to export "untracked" markers in Arena, only markers associated with a rigid body or skeleton can be exported.

More specifically, "untracked" means the software does not try to consistently label a marker from frame to frame (it uses the skeleton and rigid bodies to help accomplish this task). So if they were to be exported, it would be a "point cloud" of unlabeled markers in random order for each frame.

You might want to view the table at the bottom of the page linked below for an overview of what each software package can export.

Are there any plans to develop a system that labels the markers from frame to frame?

We have a feature request in to label and track individual markers that are not assigned to any rigid body or skeleton. The tracks can break easily and have gaps and switch marker assignments, but it appears that our customers don't care about that and just want to get the longest tracks they can for individual markers. I understand there are many reasons for wanting this feature, like tracking clothing or a tail or something like that, so we will add it in the future.
