Setting value of keyframe not working

I have an Alembic object that has animation on it. I don't want to adjust that.

I want to be able to keyframe the "Start of Animation" option that's in the Object tab.

I can add a track, get the curve, and add a key with no errors popping up, I just can't get the value to go to anything else beside "1 F"

I think my issue is that the CKey.SetValue requires a curve and a float and the end result needs to be a baseTime object.

Here's a snippet of the code I have currently.

doc = c4d.documents.GetActiveDocument()
sel = doc.GetActiveObject()
startFrame = 200
track = c4d.CTrack( sel, c4d.DescID( c4d.ALEMBIC_START_DELAY ))
sel.InsertTrackSorted( track )
curve = track.GetCurve()
fKey = c4d.CKey()
track.FillKey( doc, sel, fKey )
fKey.SetTime( curve, c4d.BaseTime( startFrame, fps))
fKey.SetValue( curve, startFrame )
curve.InsertKey( fKey )

This code doesn't generate errors, it just doesn't add the new value of 200.
What am I missing or doing wrong?

Hi Herbie,

the CTrack needs to be set up correctly with the datatype:

track = c4d.CTrack(sel, c4d.DescID(c4d.DescLevel(c4d.ALEMBIC_START_DELAY, c4d.DTYPE_TIME))

And as the keyframe is of type Basetime, you need to use SetGeData() to set the value:

fKey.SetGeData(curve, c4d.BaseTime(startFrame, fps))

There's also another thread Questions regarding Keys/CKey, which may provide you some additional infos.

Aww yes! This helps tremendously. There's no doubt I will use this all of the time now.

Thank you!
