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.

curve = visTrack.GetCurve()
ckey = curve.AddKey(c4d.BaseTime(0.0))['key'] #Creates a key at frame 0
ckey.SetValue(curve, 0.4) #40%
ckey = curve.AddKey(c4d.BaseTime(1.0))['key'] #Creates a key at frame 30
ckey.SetValue(curve, 1.0) #100%
c4d.DrawViews(c4d.DRAWFLAGS_FORCEFULLREDRAW) #Update the viewport and the red dot icon

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().

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