## **Notes**

---

- Set the main material of the object as the Base material.
- Increase Group count only when additional override groups are required.
- Maintain clean, organized naming for lights and materials to prevent confusion.
- Use the Include environment only when the environment lighting should influence the override.
- In simple setups, utilize one base material and one override group.
- In complex setups, organize groups by light purpose, such as key light, reveal light, rim light, or environment light.
