Can symmetrize by used with the multires modifier? I was sculpting a hand on a character with a multires modifier, and I hid the rest of the character (including the other hand). Because the other hand was hidden it didn't get effected by the sculpting symmetry. So my question is, can the sculpting that I did on that hand somehow be mirrored to the other hand while still keeping the multires modifier? Something similar to the Symmetrize feature of Dyntpo?
Yes, you can use the edit-mode Symmetrize tool.


  EditMode -> Mesh (Menu) -> Symmetrize




Note, there was a bug with Multi-res modifier which is now fixed in daily builds and will be included in the 2.77 release (commit).
