I don't think they kept up with the version of the Poser SDK while Poser was still in the hands of Smith Micro.

Poser scenes worked in Vue because of an SDK which allowed hosting of the scenes. There was no guarantee that they would work between updates of Poser, but so long as some things didn't change, it should have worked. That said, I would imagine they are so out of sync that it won't work. Shade 3D also had this capability.
