I am trying to do automatic weighting on this object, but I am getting a "Automatic Heat Weighting: Failed to find a solution for one or more bones".

I have tried multiple things to fix this:

  • Applied: Location, Rotation & Scale
  • Recalculated Normals
  • Removed all modifiers

I still cannot get it to work. Here is the file if you want to take a look:

Try adding a subsurface modifier to the meshes you want to parent before you parent them. You can remove it later. For some reason it should work.

  • $\begingroup$ Thanks, I haven't had a chance to test it out, but I will take a look $\endgroup$ – Get Off My Lawn Jun 17 '15 at 15:02
  • $\begingroup$ After testing, this worked! Sorry for the delayed response $\endgroup$ – Get Off My Lawn Jun 17 '15 at 15:07
  • $\begingroup$ I tried this option and it didnt work, cuz when I tried to pose The body(mesh) didnt move with armature and clothes (mesh). $\endgroup$ – Robby Crawford Whispers LTD St Sep 18 '18 at 3:11

By your question I suppose that you are using the "With Automatic Weights" method.

This method works better with manifold meshes. The size of the bones also influences the result: bigger bones will attract more vertices. Don't forget that one can add remaining parts by hand later by using vertex groups.

I tested user14351's method and it works for your model (except for the teeth) . You need to add a subsurf modifier before parenting the armature to the mesh.

    $\begingroup$ by non-manifold I think you mean manifold :) $\endgroup$ – Jaroslav Jerryno Novotny Sep 16 '15 at 19:08
  • $\begingroup$ Indeed @Jerryno! Corrected. Thank you so much for pointing out the error :). And sorry for the inaccuracy everyone! $\endgroup$ – chicOrtiz Sep 8 '16 at 15:47
