The Poser Issue - Deeper Than You Think :

I have another poser problem…when importing a poser 7 model into zbrush 3.1 and subdividing with smoothing turned on, two strange wires/polygons sets appear from the chest of the model to the chin. When smoothing is not turned on and the model is subdivided the wires do not appear. I want smoothing on my subdivided model. Is there a way to fix this problem or can I smooth after I subdivide? thanks
