Quote - However, we lack a spec for OBJ.

The spec exists as extracts from Alias|Wavefront, Inc. manuals (OBJ -> http://paulbourke.net/dataformats/obj/ MTL -> http://paulbourke.net/dataformats/mtl/) Because the format is line based, you don't have to do anything sophisticated (or even bother worrying at all about rubbish) when parsing to effectively filter out just about anything that isn't a "real" part of the geometry.

P.S. I'm very much still alive :tt2:
