I made a model in rhino, but it was kinda rough and filleting surfaces suck in rhino. So i imported it into cinema 4d and put the surfaces in null groups. Then I put the one containing the body of the car in a hypernurbs, hoping it would do its whole curvey smoothing effect to all of the pieces together. It does it to all of them, but it does it to them all seperate.

Any suggestions on what i should do to get it all smoothed out?
