Since you can just use the circle tool I'm not sure why it'd matter how many points it creates. Also there's times where I use a circle to create a round corner on a right angle since fillet doesn't always five desirable results if the adjoining segments aren't the exact same length, a circle made of quarters lends itself…
The edge loops around the eyes and mouth look good, but the jaw line and rest of the face need some cleaning up. You want to limit 3 and 5 vertex poles, the ones I circled can cause issues while animating (ignore the one circled on the middle left, I got circle happy) The cheeks edge flow should be similar to what I drew.
this has come up before but i've yet to find a solid solution so i'm bumping the request. anybody know of an automated / scripted solution to extrude / inset a face with a circle of N edges ? or. chamfer a vertex to similar result ? maya specific. thanks
