--------- Hi, I am trying to add a absolute pose morph to the pose morph tag in C++. Below is code that adds a new morph to the tag.
CAPoseMorphTag * rootPose = (CAPoseMorphTag * )clone->MakeTag(Tposemorph, nullptr); rootPose->InitMorphs(); C4DAtom * rootAtom = (C4DAtom * )rootPose; rootAtom->SetParameter(DescID(ID_CA_POSE_POINTS), GeData(1), DESCFLAGS_SET_0); CAMorph * morph = rootPose->AddMorph(); morph->SetTarget(rootPose, document, obj); morph->SetMode(document, rootPose, CAMORPH_MODE_FLAGS_COLLAPSE, CAMORPH_MODE_ABS); morph->Apply(document, rootPose, CAMORPH_DATA_FLAGS_POINTS); rootPose->UpdateMorphs(document);
This code fails to set the morph mixing mode to absolute. I've also tried to set the mixing mode via SetParameter using ID_CA_POSE_MIXING. But this crashes C4D.
C4DAtom * morphAtom = (C4DAtom * )morph; morphAtom->SetParameter(DescID(ID_CA_POSE_MIXING), GeData(ID_CA_POSE_MIXING_ABS), DESCFLAGS_SET_0);
I noticed that the mixing parameters are inactive. Could this be related? I have an alembic hierarchy. And I am generating a polygon version of that hierarchy. Each object in the hierarchy has a pose morph tag that targets the alembic equivalent object.
How do I correctly add morph targets with the correct mixing mode?

Figured it out, you have to set the pose morph tag's active morph index. Like this:
rootPose->SetActiveMorphIndex(0); rootPose->SetParameter(DescID(ID_CA_POSE_MIXING), GeData(ID_CA_POSE_MIXING_ABS), DESCFLAGS_SET_0);
This seems to select the pose morph in the pose list, allowing you to access the parameters.
