Nance, I just skimmed over that other thread you linked to and... If you want to create an entire new layer(s), (as opposed to just some area of the mesh)it's actually pretty easy to do... just duplicate ALL of the 'f' lines (the facet lines), along with the intermixed 'usemtl' and 'g' lines, then go back and change the material names used in the 'usemtl' lines to something unique. No need to do anything with the 'vt' lines, unless you plan to change the values used in them (the actual texture coordinates). So basically, you copy/paste the entire section section of 'f' lines (including the 'g' and 'usemtl' lines), then edit the material names to be unique. Et voila. Cheers, - Keith
