I used Mixamo, so it changed the bones.

You need to have each bone "assigned" to the mesh with weight painting. The easiest way to do is is to have Blender do it for you.

In object mode, select the mesh, and then the armature. (the order matters) Then, hit Ctrl+P to parent the armature to the mesh. Use the option, "with automatic weights". Please note that will clear all previous weight assignments.

I hope that works for you!

  • $\begingroup$ On the mesh, you need to have a vertex group for each bone in your armature, so each bone can deform it by however much you painted it. $\endgroup$ Nov 11, 2023 at 15:53

  • $\begingroup$ I have no clue. At this point, I would start fresh with the rig, but other than that, I don't know. I'm sorry I wasn't able to help you fix this! $\endgroup$ Nov 11, 2023 at 19:01
