Swapping out SkinnedMeshRenderers and Armatures with One Animator

I have an arms SkinnedMeshRenderer + armature, and a gun SkinnedMeshRenderer + armature.

These both use one animator which is on the parent object.

Here is what the hierarchy looks like:

View Model Holder (with animator)
--- Arms Armature
--- Arms Mesh
--- Gun Armature
--- Gun Mesh

At runtime, I switch out animator controller overrides, and also I switch out the gun Armature and Mesh.

Here is my problem though, the animator seems to not want to move the bones on the gun armature when I instantiate the prefabs.

For example, I instantiate the gun mesh and armature like so:

View Model Holder (with animator)
--- Arms Armature
--- Arms Mesh
--- New Gun Armature
--- New Gun Mesh

The animator does not move the bones of the Gun Armature and thus does not move the mesh, even though I use a different RuntimeAnimatorController override.

I've also made sure that the Gun Mesh is using the Gun Armature bones, so yes they are linked.

However, when I spawn in the "View Model Holder" object as a whole (with arms attached to the gun in a prefab), it seems that the animator is linked to the Gun Armature properly, but I need to be able to swap out arms and guns independently.

I've tried calling Animator.Rebind(), but it doesn't help.

Can anyone help out? Thanks a lot in advance!

 

Solved: One of the bones in the animation was getting "(Clone)" appended to it's name. Fixed with toolArmature.name = toolArmature.name.Replace("(Clone)", string.Empty);
