Hello Joltrast, sorry but I couldnt understand the issue you are having, can you please elaborate more. 

"I'm not sure what I did wrong my G3F.obj does not quite match G2F (the grey G2F doesn't match the flesh base of G3F) even with G2F parameters dialed to 100% and mesh set to base and 0. (I left Render Sub D as 1 as you didn't mention it). When I try to load the objs as morphs it says the geometries don't match."

Render Sub D has no effect, so thats not part of the problem. After transferring your morph to your obj, make sure you once again export it with zero subdivision. One of your objs must have exported with subdivisions on or if you have exported your mesh to some modelling app like Blender, you might have unintentionally changed the vertex order. Those 2 are the only reasons I can think of why you are getting that error "geometry doesn't match". 

In your second post, though it is not a full snapshot but the G3F obj is matching well with G2F.
