    Pulling my hair out trying to keyframe the current visibility % for a display tag on the currently active object in C4D R15 using Python

    I'm trying to keyframe it at 0%, change it to 100% a few seconds later and then keyframe that.

    Can someone help please with some tips or example code? I can make keyframes, move around the timeline, etc without issue just stuck on how to do display tag keyframe specifically.

          ckey.SetValue(curve, 0.4)                      #40%  
          ckey = curve.AddKey(c4d.BaseTime(1.0))['key']  #Creates a key at frame 30

      c4d.DrawViews(c4d.DRAWFLAGS_FORCEFULLREDRAW)       #Update the viewport and the red dot icon  
    if __name__=='__main__':

    as you can see in Scott's example animation data is stored in a animation track represented by the class CTrack. For each animated parameter the host object stores a CTrack object. This CTrack can be obtained with FindCTrack(), if no Ctrack exsists one can be created and then added to the host object using InsertTrackSorted().

    A CTrack contains a CCurve and that CCurve contains the actual animation keyframes. These keyframes are represented by CKey objects. You can add a new key to a curve using AddKey().

    Best wishes,

    Thank you Scott for the demonstration and Sebastian for the explanation! It finally works :D
