I think what triarius was asking about was in refrence to bringing objects into Cinema 4d for the purpose of creating morphs, if Im wron on that assumption I appologise. unfortunately while obj format does import fine into C4d, the import process does change the vertex order slightly and if you do not use some kind of filter or as steves tutorial suggests using another format to import you will get scrambled morphs, not a pretty sight I assure you ;)
