@Keith and puppy, thanks for your comments.
@FredP, Thanks, I sent you an e-mail.
@All, no doubt you've noticed the hard edges on the models. I'm using ms3d, and while smoothing seems to work well in the editor, it seems to get lost when exported from ms3d.
What little I could find on assigning smoothing groups in ms3d is difficult to follow, and seems to be a way to remove auto-smoothing rather than applying it.
Anyone with ms3d experience who can shed some light on smoothing and getting the results into the final product, your help would be most appreciated.
Besides ms3d, I use LithUnwrap 1.3 and PhotoShop7/Paint.net.
Best.
