Mesh deforms in Steps

So lately I had a strage problem with my mesh. After parenting it to the armature it gets deformed in ‘steps’ reating edges:

I have no idea how to fix this. I checked the weight painting it seemed fine.

Additional info which may be important:
Mesh imported from Zbrush, armature appended from other blend file.

Thank you!


You need to post a wireframe image of the mesh, I think that you have some “iffy” topology there… You could also post the blend file for us to look at.
