The buildbot version of Blender just got itself a new modifier called Corrective Smooth based on a smoothing algorithm called Delta Mush. It makes deformations suck much less,, as you can see here by the way it effortlessly cleans up Gronky’s otherwise munty shoulder.

If you’ve never downloaded one of the nightly builds of Blender and you do any rigging or character animation at all, you’re missing out on sexy stuff like this by waiting for the stable release. 🙂
