Hello again,
I have a model with a Pose Morph tag.
I can get the tag from the object. What I want to achieve is control the values of the different poses through code and keyFrame those. I actually only need to toggle them on or off as they'll either be 0 or 100%,
I've toggled visibility of a model on and off using CTrack, CCurve and CKey. Would it work similarly with the poses?
How can I loop through all the poses and toglle them on and off and keyFrame that?
Edit (by @ferdinand consolidating posts):
So here's what I got so far:
face = doc.SearchObject('Body') tpose = face.GetTag(c4d.Tposemorph) morph = tpose.GetMorph(2) morphId = morph.GetID() descId = morphId * c4d.ID_CA_POSE_ANIMATE_CNT + \ c4d.ID_CA_POSE_ANIMATE_OFFSET + c4d.ID_CA_POSE_ANIMATE_STRENGTH print(descId) smirkTrack = obj.FindCTrack(descId) if not smirkTrack: smirkTrack = c4d.CTrack(face, descId) print(smirkTrack)
It works up until the point it has to create the CTrack:
1201 Traceback (most recent call last): File "C:\Users\Augustin\AppData\Roaming\Maxon\Maxon Cinema 4D R25_1FE0824E\library\scripts\test.py", line 80, in <module> File "C:\Users\Augustin\AppData\Roaming\Maxon\Maxon Cinema 4D R25_1FE0824E\library\scripts\test.py", line 46, in main BaseException: the plugin 'c4d.CTrack' (ID 5350) is missing. Could not allocate instance
It doesn't return this code if I use another descID like the one for editor visibility.
I realise my DescId or the way I calculate it is what's wrong but I don't where to find the documentation for that.
So I'm making progress. I was obviously not looking in the right place to find the DescId.
I went back to the doc and found this:For a plugin and special tracks you pass the ID. tr = c4d.CTrack(op, c4d.DescID(ID, ID, 0)) IDs for Cinema 4D’s special tracks are: CTpla PLA. CTsound Sound. CTmorph Morph. CTtime Time.
So I tried:
descId = c4d.DescID(c4d.CTmorph, c4d.CTmorph, 0)
But get hit with:
TypeError: argument 2 must be c4d.DescLevel, not int
I then realised it should be:
descId = c4d.DescID(c4d.DescLevel(c4d.CTmorph, c4d.CTmorph, 2))
So it would be good to fix the documentation
Here's my code so far:
visTrack.FillKey (doc, obj, keyDict["key"]) print(c4d.Tposemorph) face = doc.SearchObject('Body') tpose = face.GetTag(c4d.Tposemorph) print(tpose.GetMorphCount()) firstMorph = tpose.GetMorph(2) morphId = firstMorph.GetID() print(morphId) descId = c4d.DescID(c4d.DescLevel(c4d.CTmorph, c4d.CTmorph, 3)) smirkTrack = face.FindCTrack(descId) if not smirkTrack: smirkTrack = c4d.CTrack(face,descId) smirkCurve = smirkTrack.GetCurve() # kdict = curve.AddKey(curTime) # kdict.SetValue(0) # smirkTrack.FillKeu (doc, face, kdit["key"]) # Creates a keyframe in the memory key = c4d.CKey() # Fills the key with the default data smirkTrack.FillKey(doc, face, key) # Defines the key value key.SetValue(smirkCurve, 0) # Defines the time value key.SetTime(smirkCurve, curTime) smirkCurve.InsertKey(key)
Unfortunately it doesn't seem to have any effect on the values of the pose, nor the keyFrames.
I've also tried applying all of the track and curve to the tag rather than the object but it did not have any more impact. I think I'm at the point where I could use some help.
Making progress:
for i in range( tpose.GetMorphCount()): descID = tpose.GetMorphID(i) currentValue = tpose.GetParameter(descID, c4d.DESCFLAGS_GET_NONE) print(descID, currentValue) tpose.SetParameter(descID, 0, c4d.DESCFLAGS_GET_NONE )
returns all the values of the morphs as expected. I suppose they're the descIds I should use for the keyframes. But should the keyframe be on the tag or on the object the tag belongs to?
I tried something like this:
for i in range( tpose.GetMorphCount()): descID = tpose.GetMorphID(i) currentValue = tpose.GetParameter(descID, c4d.DESCFLAGS_GET_NONE) print(descID, currentValue) tpose.SetParameter(descID, 0, c4d.DESCFLAGS_GET_NONE ) track = tpose.FindCTrack(descId) if not track: track = c4d.CTrack(tpose, descId) tpose.InsertTrackSorted(track) curve = track.GetCurve() keyDict = curve.AddKey(curTime) track.FillKey (doc, tpose, keyDict["key"])
to no avail, I also tried the same thing with the object and it didn't do much either
I also tried like this:
for i in range( tpose.GetMorphCount()): descID = tpose.GetMorphID(i) currentValue = tpose.GetParameter(descID, c4d.DESCFLAGS_GET_NONE) print(descID, currentValue) tpose.SetParameter(descID, 1.26, c4d.DESCFLAGS_GET_NONE ) track = face.FindCTrack(descId) if not track: print('no') track = c4d.CTrack(face, descId) face.InsertTrackSorted(track) curve = track.GetCurve() # keyDict = curve.AddKey(curTime) key = c4d.CKey() key.SetValue(curve, 0) key.SetTime(curve, curTime) curve.InsertKey(key)
Didn't do much more. However it does appear that the CTracks exist.
My brain is fried. I'm admitting defeat for tonight.
