I'm modelling high-poly tire with tread. I have problem with sharp edges on tread connection(array+circle modifier). Have you got some ideas to correct it to smooth surface?
To help round out the flat tread sections, I initially though using a spherical profile option in proportional editing would have done the trick, but the Inverse Square profile option proved to be more fitting for me.
To quickly toggle off/on proportional editing...
While in Edit mode hit O.
Just to the right of this UI toggle there are profile options to choose from.
To adjust influence, scroll your mouse wheel up/down until it begins falling off comfortably.
