I played around with AOI and didn't particularly like it, but that's only a matter of taste. The biggest drawback to me me is that it only seems to edit meshes made of three sided polys which is a svevere limitation when working with other apps. Useless for Poser morphs for instance. Or have I missed something? It's loads of great features though and for a free app it really can't be beaten, especially on Mac where there is less choice among free 3d apps. - Baz
