Maya python 检查网格是否有 animation

Question

I'm looping through the selected objects in maya and trying to check if they have either Transform or Deforming animation. Is there a way to check for this? I found out how to check for the Transform animation, but not sure how to check deformation animation, which would be vertex based animations or bone driven animations.

import maya.cmds as cmds


def hasTransformAnimation(transform):
    if cmds.objExists(transform):
        animAttributes = cmds.listAnimatable(transform)
        for attribute in animAttributes:
            numKeyframes = cmds.keyframe(attribute, query=True, keyframeCount=True)
            if numKeyframes > 0:
                return True
    return False


def hasDeformationAnimation(transform):
    return False



sel = cmds.ls(sl=True, l=True, type=('transform'))
for o in sel:
    print('Transform', o, hasTransformAnimation(o))
    print('Deformation', o, hasDeformationAnimation(o))

Answer 1

I've done this by simply checking if either the transform node has incomming connections to the transformation attributes or if the mesh shape has in incoming connection connected to the inMesh attribute. The only drawback of this method is that you cannot see if the geometry is really animated or if it is static.
