Lighting Man provides an interactive viewport tool for positioning lights based on specific surface reflections. By reading the object geometry under the cursor, the addon automatically calculates the exact angle and location required to generate a reflection at that point. This workflow is particularly useful for precise edge highlighting on metallic and glossy materials.

The tool features an interactive placement mode with hotkey support for real-time adjustments. Users can modify light distance, size, and intensity, as well as switch between point, sun, spot, and area light types directly in the viewport. A visual reflection line helps visualize the light path, while an alternative normal mode allows lights to be aligned precisely to a face's normal direction.
