So i added two bones to the armature after I parented the armature without those two bones to the mesh. I named them mouth lower and mouth upper, but when I select the mesh they are not in the vertex groups. How do I fix this?The two highlighted bones are the ones im talking about


1 Answer 1


Find out the names of the newly-added bones

It's listed in your Properties Panel, under Item.

Bone name

Create Vertex Groups on your Mesh with those names

Bones look for vertex groups with corresponding names to deform.

Adding and naming a new bone

Paint on some weight

Paint on some vertex weight

You can do this from Weight Paint Mode, or alternatively use the Weight slider to specify a weight before clicking Assign. Always pay attention to which vertex group you have selected when weight painting.

    $\begingroup$ Thank you! Was following a tutorial and they missed this important part. Since I was rigging a different gun than the one in the tutorial I could not understand why all my parts didn't move with the parent bone. This solved my issue! :) $\endgroup$ Aug 3, 2022 at 17:58

  • $\begingroup$ definitely! I'm so new to blender and come from a programming background, so still have a lot to learn. If you don't mind, maybe you can have a look at an issue I am having now? I posted a question here - blender.stackexchange.com/q/271404 $\endgroup$ Aug 7, 2022 at 21:03
