## Troubleshooting

### How to rename something?

You can rename objects with F2 but in many other places you need to double click the name with your mouse.

### What is neutral_bone?

When you export a rigged model with Blender in glTF format, you will sometimes notice a `neutral_bone` in the exported data.
This is because some vertices were not assigned a vertex group.

In edit mode, go to `Select > Select all by trait > Ungrouped vertices` to find the problematic vertices and delete them.
