Hi Dapper John, I wish I could offer some insight on the .hxn -> .car issue. That is a bullet proof method for me. But so is the .obj export. So, if you're experiencing a problem object with the .obj export, do a Save-As with the Hexagon file and then delete that one object. Then try the .car export. If that works ok, then there is some "illegal" topography in the object in question as far as Carrara is concerned. I have occasionally created files that will consitently create problems for other 3d apps. It can usually be traced to a single object that I can re-make and have all the problems go away. Please keep us in the loop on this one. It's good to hear how exceptions are solved. Mark
