RH Morph Animator carries mesh motion from Blender into Daz Studio. Bone animation stays in Daz. On top of it, the surface itself animates: vertices move, and the skeleton does not have to. This is how you animate a mesh inside Daz and play back a simulation that was computed in Blender.

A normal Daz morph stores one shape. This pair turns mesh motion into a sequence of morphs: one morph per frame, with a linear blend from frame to frame. The Daz timeline plays them together with the bone animation that is already there.
