Looks like smoothing will fix that. Select the model mesh. Click at the small E box at the attributes column close to the model - that one sends you to the smooth box. Sellect the angle and click at the left sphere to start. If you plan to do meshes booleans don't forget to set the make solid dot - that's the only place with this control. Sometimes smoothing does weird things to Poser meshes, specially with Eve models.
