rippled pinch marks on circle with subsurf

After a week of searching google, I’ve hit a brick wall with a model I’m working on. I’m trying to model a peanut butter cup, and it seems like no matter what I do to the circle I’ve made for the top, its subsurf mod creates strange ripply pinch marks between every two faces. It really looks horrible when rendered


Now I thought the marks were shadows from the wrapper, but even when I moved the wrapper out of view, the marks are still there.


I’ve tried to change the centre of the circle in an Ngon, tried removing all subsurf creases I had made, tried adding more edge loops (which undoubtedly made it worse), and tried moving the edges coming from the center outward up and down. I will supply the .blend below in case it helps. I am looking to have a nice, smooth, chocolatey surface. What can I do to get the ripply effect to go away?

in edit mode select the inner rings and in the tool tab , looptools press circle to tidy up the rings
looptools may be an addon, you’ll be able to enable it in the user preferences.

and you dont need 6 levels of subsurf. that’s crazy

It’s largely down to your geometry and is being aggravated by the subsurf.

You should be OK, if you change the geometry to something like:

Also, those subsurfs really aren’t needed; especially the one on the wrapper. Even if you did need them, there is no visible difference past level 3; so having it set to level 6 is a waste of resources.

edit:
Bah, beaten to it. :slight_smile:

After reading the replies here, I tried both of the suggestions, but I’m still getting pinching that’s just as bad.

Something like this?
