I'm really confused because the only bones I accidentally deleted before are the pelvis and heel bones, which I then restored to their exact original states. I'm not really sure what to try in this situation.

Here is the error I got:

RIGIFY ERROR: Bone 'thigh.L': Input to rig type must be a chain of at least 4 bones.

Incorrect armature for type 'limb_rigs'

  • $\begingroup$ Sounds as if you may have restored them but not linked them back into the armature correctly. Share you file so that someone can test it here. pasteall.org/blend and post the link to it into your question. $\endgroup$

In the Metarig Heel bone has to be child of the foot bone, in order to work.

When in doubt, go to edit mode and add a Rigify sample of the part you're working on, parent it and snap it into position or analyze how is it constructed.

Every chain of bones has a Rigify Type set on its first bone (you can read it in pose mode) and Rigify Types have a Parent/child relationship according on how the rig is structured.

  • $\begingroup$ I did that and analyzed how its constructed, but it all seems to be put together correctly. I did notice that the toe bones weren't parented to the foot bones but correcting that didn't fix the issue. I'm a bit new to rigging so did I miss something? $\endgroup$ Jun 11, 2022 at 20:24
  • $\begingroup$ edit: the toe bones werent childs of the feet bones $\endgroup$ Jun 11, 2022 at 20:41
  • $\begingroup$ Nevermind I just restarted the rig. Thanks anyways. $\endgroup$ Jun 11, 2022 at 23:03
