Blending booleaned object

[mdhan82]

Hello,

I'd be grateful if anyone could help with what I hope would have an easy solution.

I am trying to smooth the borders of a booleaned object to blend in with the object it was booleaned against. 

I included a screenshot with an example to better explain my question. The box is the object of interest, and the bunny is the object that was boolean subtracted from the box. Ultimately, I would like to smooth the borders of the box so that it seemlessly blends with the contours of the bunny's back (red lines). I tried using the Robust Smooth feature, but what I always get is "rolling in" of the undersurface of the box, preventing a nice seamless blend.

Any advice would be VERY MUCH appreciated. Thank you and have a wonderful day!

You can set the brush to NOT affect an area of a different facegroup.

Generate a single facegroup for an area you are okay with being modified, and another for one you do NOT want modified. Then under your brush set you filter to "Restrict to Groups".
