Hey Jonathan I think I finally understand. I literally saw this as soon as you posted it, but it took me until now to sort of understand. So from what i understand only the end of the loop can possibly have a sharp edge? Is that correct? For example in the img below the loop continues all the way from the top to the bottom and only the two ends are sharp. Even if it seems to have a sharp end without subdivisions.


, however if you end the loop appropriately at each sharp point you will get the sharp edges as seen below.

Please correct me if I’m wrong (crosses fingers) ! 🙂
