Q: bug or just me? can not control airbrushed shape

while playing and leraning with f.mahoney's excellent tutorial

http://www.fcp.co/final-cut-pro/tutorials/1837-controlling-shapes-the-mysteries- of-osc-in-final-cut-pro-x-revealed-part-2

 

about controlling Shapes via OSC, I stumbled over this odd 'effect':

My situation, a shape, a pic, Track Points behavior:

when I move the crosshair, shape moves too - fine:

Now, I change the Brush Type to Airbrush:

no more tracking/moving!

 

... can I fix that? Or does tracking not work with Airbrushed shapes??

Mac mini, OS X El Capitan (10.11.2), Pana707/Sony NEX 5/Pana FZ1000

    yep, but?

    Intentional? Any reason why? is'n airbrushed shape not a shape? If so, why then control points??

     

    ... filed a bug report ...

    repeatable, on diff. machines, unwanted = bug.

    … - at last for me....

    Move the playhead. Start playing the project and the airbrushed line will follow the track points. You might find the same is true in FCPX, but once the project is playing/rendering, the animation should work.

    … ooops, THAT simple??

    Have to check in a plugin project, with a linked OSC ... that would be great.

     

    now, that is interesting:

    indeed, it is a diff 'user experience':

    with brushtype Color, the one trackpoint follow the OSC

     

    but you can not keyframe it:

    when I set kf to the OSC, the whole line follows the OSC; not just the one point ..... grrrrrr

    The keyframing behavior has been changing... but it still does not work completely. Lately, there's one OSC control of the group that "takes over" the position of the entire shape. It's like "it's almost there"...

     

    Awhile back, I put out this template and the demo video https://www.youtube.com/watch?v=cYkqTiOrJLM that shows the playhead has to be moved sometimes to make the animation continue.
