I am trying to delete all animation tracks in the document.
The following code successfully removes all tracks except those under "Shader Properties" in the shader effector objects—for instance, the gradient property. Do I need to access these particular tracks through some other means? Are these tracks somehow different from the others?
Thanks.
import c4d from c4d import documents
def GetNextObject(obj) : if obj==None: return None if obj.GetDown() : return obj.GetDown() while not obj.GetNext() and obj.GetUp() : obj = obj.GetUp() #print (obj) return obj.GetNext()
def RemoveTracks(obj) :
for track in obj.GetCTracks() : #if (track.GetCurve().GetKeyCount() > 0) : track.Remove() def main() : obj = doc.GetFirstObject() if obj==None: return while obj: RemoveTracks(obj) obj = GetNextObject(obj) c4d.EventAdd() if __name__=='__main__': main()

I am not sure how this is meant. You are stepping though all BaseObjects in the document and remove all CTracks containing at least one Ckey. A BaseShader is obviously not a BaseObject and therefore it will not get covered.

Thank you. That was very helpful.
Here is the updated code for anyone else who might have this issue.
def GetNextObject(obj) : if obj==None: return None if obj.GetDown() : return obj.GetDown() while not obj.GetNext() and obj.GetUp() : obj = obj.GetUp() return obj.GetNext()
def RemoveTracks(obj) : for track in obj.GetCTracks() : #if (track.GetCurve().GetKeyCount() > 0) : track.Remove() shader = obj.GetFirstShader() shadertree(shader)
def shadertree(shader) : while(shader) : shaderTracks = shader.GetCTracks() for shaderTrack in shaderTracks: shaderTrack.Remove() # Check for child shaders if shader.GetDown() : shadertree(shader.GetDown()) # Get the next shader shader = shader.GetNext()
def main() : obj = doc.GetFirstObject() if obj==None: return while obj: RemoveTracks(obj) obj = GetNextObject(obj) c4d.EventAdd() if __name__=='__main__': main()
