I can see how if you morph genesis into whatever character you're wanting in DS and then export it out and bring it into poser, but not morphing inside poser, due to the low poly mesh. DS has some way of increasing the mesh density as the character is being shaped, poser doesn't do that. 

It would be nice if poser did do that. I don't see why it would be so difficult to incorporate, but I'm not a programmer. My knowledge of python is rather limited, but I have books on it.
