How to make part of the mesh follow a bone without deforming it I am rigging a model of a creature which has sort of shields on its front legs, but I don't want those shields to be deformed, when I pose the leg. The rest position looks like this:

 

But when I use the bone, which controls the lower arm, it turns out like this:



How can I make the shield follow the arm without deformation? It's attached to the arm (I can't separate it).
Like it was stated, you need to remove unneeded vertex groups from the shield.

In Weight Paint mode, select the vertices you want to clear. Back in the Vertex Groups, click the down arrow icon. There's an option to either remove all groups from selected vertices, or only the active group. Best to remove all groups in your case and manually add the driving group back.
