The .zip file does include an .obj file, it's just that it's not needed for the cr2 to load. It's just intended for creating MTs (I guess). shdcstr: as allerleirauth says, it's a problem with the vertices' order. Maybe you have inverted the objet while working on it? Did you have to convert to other format when exporting and before importing to Poser? Wich 3D program have you used?
