Hi I am also a Realflow4 C4D user
But I also have the Amazing Interposer Pro plugin®
that loads poser figures directly from my runtime with full functionality so can animate him in C4D to match my loaded animated Realwave mesh ( See pic)
but I am not sure how you would do this with just poser
other than just animating him/her manually in poser and hoping for a decent match in C4D.
