todd71, The duplicate object looks strange, because it has "reversed normals". In the interactive renderer, Carrara displays the left arm "inside out", which looks weird. In the final render, all surfaces are double-sided, and the reversed normals don't hurt. However, it's often difficult to arrange or align an object with reversed normals. In this case, you can open the object in Vertex Modeler, select the entire object, and choose menu "Polymesh > Reverse Polymesh Normals".
