I loaded the OBJ of a freebie shirt for V4, brought it into the cloth room, and gave it a nice fit for my character. 

I now wanted to save that OBJ out as a Morph Target, so I selected only that "prop" on that single last frame, and File->Export->Wavefront OBJ

I've tried with no settings checked, and then with both "As Morph Target..." and "Include Existing Groups..."

In either case, I then load the shirt figure, conform it, then select Object->Load Morph Target

...it says the "Target Geometry has the wrong number of vertices"???  I used the original OBJ from that figure, and I didn't think the cloth room changed the vertice count?

I am missing something, any ideas?
