Mudbox Crash 2016: Smooth tool

Smooth tool has become slightly unstable in Mudbox 2016. When having more than one object in the scene which has been retopologized, using smooth tool messes up the modell completely leaving you with extreme spikes or just overall dragged out geometry and sometimes an out of memory crash or a freeze.

There is no quick fix that I’ve found, but a work-around.
1) select the object which smooth tool messes up
2) go to “file” then “export selected”. Name it and set the file type to .obj (this causes the file information to be limited to vertices and uvs)
3) delete the object in your scene.
4) import the obj-file you previously exported

…and now you can use smooth tool.
