Unreal Engine Issues and Bug Tracker (UE-147267)

Steps to Reproduce

Animate groom hair in Maya with rotation.
Export the interactive groom to alembic file.
Import to UE and add groom and groom cache file to an sequencer.
Play the sequencer and the lost of shape of the groom could be found. Although the root of the groom is animating the same with Maya, but he end of the hair is pointing the original direction same with frame 0, which caused the shape-losing problem.
For demo project and assets, please see the attached.
