Switch subdivision to OFF in the DSN support script and the "cartoon line" will be gone.

Then switch "Skinning Method" for her to "Poser Unimesh"

Then set Subdivision Levels for Render to "1" in the body actor.

Genesis 1/2 will now use Poser's own subdivision algorithm. The OpenGL preview will be the original low resolution, but the actual render will be subdivided.

 

Can't help you with your GoZ problem, though.

But AFAIK you can only actually morph the low resolution mesh, as the subdivided high res mesh is only virtual.
