Setting Morph Mixing to Relative But still Remains Absolute

bentraje

Hi,

I am creating a morph tag and setting the mixing to a relative but the problem is it remains absolute.
You can see an illustration of the problem here:
https://www.dropbox.com/s/22e33ii8yvr14sw/c4d164_python_relative_morph_tag.jpg?dl=0

You can see the working code below:

import c4d
from c4d import gui

# Main function
def main():
    obj_list = doc.GetActiveObjects(c4d.GETACTIVEOBJECTFLAGS_SELECTIONORDER)
    
    morph_tag = obj_list[-1].MakeTag(c4d.Tposemorph)
    morph_tag[c4d.ID_CA_POSE_POINTS] = 1
    
    # Create the Base Pose
    c4d.CallButton(morph_tag, c4d.ID_CA_POSE_ADDMORPH)
    
    
    for obj in obj_list[:-1]:
        morph = morph_tag.AddMorph()
        morph.SetName(obj.GetName())
        
        count = morph_tag.GetMorphCount() 
        morph_tag.SetActiveMorphIndex(count-1)
        morph.SetMode(doc, morph_tag, c4d.CAMORPH_MODE_FLAGS_ALL, c4d.CAMORPH_MODE_REL)
        #morph_tag[c4d.ID_CA_POSE_MIXING] = c4d.ID_CA_POSE_MIXING_REL
        morph_tag[c4d.ID_CA_POSE_TARGET] =  obj
        morph_tag.UpdateMorphs()      
      
    c4d.EventAdd()

# Execute main()
if __name__=='__main__':
    main()

Hi @bentraje The python doc should be improved in this regard.
If you look at the C++ doc you will see that SetMode is not the correct way to go to convert internal data, but SetParameter.
SetMode only defines how the tag should read the internal data stored.

Additionally, you may found the C++ CAMorph Manual interesting.

Cheers,

Thanks for the response. I tried this code:
morph_tag.SetParameter(c4d.ID_CA_POSE_MIXING, c4d.ID_CA_POSE_MIXING_REL, c4d.DESCFLAGS_SET_NONE)

It doesn't error out but it has the same effect as above. The mixing is set to "Relative" but the icon still shows "A".

Are there any additional settings I should look out for?

The A seems to be present until there is a target.
So using the next code fix the things, by storing the data first absolutely then converts them to relative.

import c4d


# Main function
def main():
    obj_list = doc.GetActiveObjects(c4d.GETACTIVEOBJECTFLAGS_SELECTIONORDER)
    
    morph_tag = obj_list[-1].MakeTag(c4d.Tposemorph)
    morph_tag[c4d.ID_CA_POSE_POINTS] = True
    
    morph_tag.ExitEdit(doc, True)
    
    # Adds the default base morph and store the data
    morph = morph_tag.AddMorph()
    morph.Store(doc, morph_tag, c4d.CAMORPH_DATA_FLAGS_POINTS)
    morph.Apply(doc, morph_tag, c4d.CAMORPH_DATA_FLAGS_POINTS)
    
    for obj in obj_list[:-1]:
        morph = morph_tag.AddMorph()
        morph.SetName(obj.GetName())
        
        count = morph_tag.GetMorphCount() 
        morph_tag.SetActiveMorphIndex(count-1)
        
        # Set Data to Absolute and link to our obj
        morph_tag[c4d.ID_CA_POSE_MIXING] = c4d.ID_CA_POSE_MIXING_ABS
        morph_tag[c4d.ID_CA_POSE_TARGET] = obj
        
        # Store the point data in the morph node
        morph.Store(doc, morph_tag, c4d.CAMORPH_DATA_FLAGS_POINTS)
        morph.Apply(doc, morph_tag, c4d.CAMORPH_DATA_FLAGS_POINTS)
        
        # Set data to Relative and remove the link
        morph_tag[c4d.ID_CA_POSE_MIXING] = c4d.ID_CA_POSE_MIXING_REL
        morph_tag[c4d.ID_CA_POSE_TARGET] = None
        
        morph_tag.UpdateMorphs()
        
    # Set to Animat
    morph_tag[c4d.ID_CA_POSE_MODE] = c4d.ID_CA_POSE_MODE_ANIMATE
    c4d.EventAdd()

# Execute main()
if __name__=='__main__':
    main()

Cheers,

RE: The A seems to be present until there is a target.
Thanks for the clarification. That make sense.
Your code works as expected.

This is just a trivial question.
In the documentation for the CAPoseMorphTag.ExitEdit it says:
Must be called before doing anything to a morph tag.

Shouldn't it be named EnderEdit? Since we are editing the morph tag or calling the ExitEdit after actually editing the morph tag?

Again trivial but just seeking some clarification.
