That robot or mecha, obviously, can never be a Genesis 8 or 9 morph... (the difference in size and morphology are brutal...)

The cr2 format (from Poser...) has its own rigging, which, In order not to complicate things, you should respect. You can convert it to duf if you want..., but it has articulations with IK, something that has been discontinued since Victoria 4...

In Daz, you can convert it to OBJ in parts, and edit them with Blender or Rhino (as in my case...)

But, honestly, I would contact this author, to be able to obtain the model, more adjusted to the original Calibretto:

And, re-rigging the entire model with bones named like daz models... (Pain in the ass! 😀 )
