Research direction

Start by reproducing the USD animation import in Maya 2022 with pymel.all and mayaUSDImport using useAsAnimationCache=True and readAnimData=True. Compare the transform-only result with the missing deformer animation and verify that the deformer applies correctly to the imported objects; the report includes an image and animation attachments for comparison.
