Skeleton3D Outline on Hover

Godot Version

4.5.stable.official

Question

I’ve found many tutorials that show how to outline a single mesh by mouse_enter / mouse_exit signals, but how can I make it work with a Skeleton3D?

This is my tree:

A great tutorial I was looking at is this one: https://youtu.be/CG0TMH8D8kY?si=vPrJXe_IkZxRBlXr&t=327

But it works for one Mesh. I need to work with a 3D Model that has several meshes. Plus, the CharaterBody3D already has its own script.

Please help!

Thank you.
