I don't have NOLF 2, can you post a pic? Do they have as much hairs as the ape?

Myrlyn is right. There is even a similar way in MED. After you had done your model mark the most inner part of it (or vice versa). If you marked the inner part, click 'select invers', copy it and delete it, then paste it. The vertices' numbers have changed. Then mark the next 'layer' of vertices/polygons, and same procedure, again, and again - until all polygons are sorted. Save!
