Please have a look at the image below, it shows two polygons sticking out awkwardly...
This was achieved by creating a simple poly thing (just messing with paint) which I then smoothed *1. I then began to paint the object exploring the UV texture editor after after automatically mapping it. Then I deleted the two polygons and put them back using append polygon tool. But as you can see they didn't go back smoothly...
I could re-smooth the object, which gets rid of the problem, but I wondered why my new two polys stick out like a sore thumb... Does smoothing do something to the surfaces other than divide them?
Tickety boo and ta ta for a bit...
