Problem with shape keys, bone doesn't move shape keys? please help!

Hi, I’m having trouble moving my character’s head bone!
Exactly where I made the changes with the shape keys, the character’s mesh doesn’t move, it gets “stuck” on something.
Can anyone shed some light on what I’m doing wrong? (I used google translator, I hope I was clear what I meant).

PS.: Just the bone under the nose that seems to work right (the only one I didn’t shape key the mouth)…

PS2.: I used Blender 3.2

Check that your controller bones don’t have ‘deform’ enabled. So that only the bones that you intend to deform the mesh are doing so.

You can see which vertex groups are affecting points:

  • Go into edit mode on the model
  • Bring up the Item panel (press ‘N’ to show it)
  • On the Item tab, there is a Vertex Weights section. This shows which vertex groups affect the selected point, and by how much.
  • The Deform tab in that section can tell you which groups will have conrtol over the point’s position.

You can use these views to show what is affecting the misbehaving points. That might help to fix it.

Thank you very much for the answer, I did as you said and in the deform tab it doesn’t show anything when I select the vertex with problem. Is that the problem? Should I have something?

PS.: I also disabled the deforming of the problem bones.

Selected tab: (deform = deformar).

I could be wring about the ‘deform’ tab on that section, but the one to the left of it will show you the different vertex groups that have influence over the selected point.

You’ll need to add vertex weights again for the deform bone that you’d want to control the points.

You could do this with the weight paint tools, or re-parent the armature with automatic weights. If you’ve made custom weight-paints, then the automatic weights will override that, so save a backup first.

I’ve just double-checked. The Deform tab does show the groups that are associated with a Deform bone (as you’d expect :slight_smile:). The ‘Other’ tab shows any weights assigned to other groups - for whatever reason, not necessarily rig-related. The ‘All’ tab, unsurprisingly, shows all vertex groups that have values assigned to the selected point.

I understand now, I didn’t know that I had to “combine” the shape keys with the weight painting, I had reset the weight painting. That’s why it wasn’t working properly…
Now I’ll have to mess with the shape keys all over again lol :sweat_smile:

Thank you so much for the help! :smile:
