Unusual. I've been modelling for 4 years in max and I import everything to poser as 3ds, then convert it to obj. I started doing this because I wasn't happy with the stability of the obj export from max. I've never had a problem with 3ds files at all. I'm sorry I can't offer a solution. It could be that some technique has been used that poser doesn't like (and that I've never used), but I can't imagine what it could be. mac
