A Scope is similar to an Xform, but with one key difference:
👉 it cannot be transformed.
Scopes are used purely for organisation. They help keep your Scene Graph clean without affecting position, rotation, or scale.
Example:
If you want to group all lights together:
root
└─ lighting (Scope)
├─ keyLight
├─ rimLight
└─ fillLight
Scopes are perfect for:
• Grouping lights
• Organising props
• Separating departments
• Keeping large USD scenes readable
