Accordion 3d model rigalembic cache animationFBX Animated for UE and Unity This rig is not based on a skeleton (joints); it uses a deformer.
This setup is not designed for direct import into Unreal Engine or Unity. You can only use the FBX file if you utilize the blend shape system in Maya, export it as an FBX, and then import it into Unreal or Unity. Otherwise, you must import the FBX file and individually animate the accordion's bellows (folds) and the center section separately within Unreal or Unity.
