Lighting is based on a layered setup of Area Lights combined with a Sun Light driven by Blender’s built‑in Sun Position add‑on. This ensures correct solar angle, shadow behavior, and overall illumination. Without the add‑on, the lighting will not match the intended result.

The project is provided in .blend, .fbx, and .stl formats. Only the .blend file includes the full procedural materials, lighting setup, and node structure; FBX and STL are intended strictly for geometry export and compatibility.
