Thank you everyone. I have tried both splitting and welding the vertices in the free UV Mapper. And it is an issue with my more cylindrical objects. If I render any cylindrical object it bulges in the middle, which is also splitting the vertices apart as well, and at the ends, the edges are smoothing, but the caps are not, which also causes it to look split apart. And this problem is not just limited to long objects as well. Adding more polygons to the ends has not helped me. It is mainly the splitting that bothers me so much; I could deal with a minor amount of bulging. Unfortunately I don't have access to my Poser computer at this time to show pictures.

The reason I can't turn off polygon smoothing is because the object has round parts that need to be smoothed. As I mentioned in my original post this was never a problem until I switched to Firefly.

I have seen a number of you mention assigning hard edges in Wings. I haven't really got into the more advanced functions in Wings and I am unsure how to do this. How do I assign hard edges?

Thanks
