**Behavior of AR Lights in the OVER App** The **AR Lights** used in the OVER application behave differently from manually created custom lights. These lights dynamically simulate the color and intensity of natural light in the real-world environment where the user is experiencing the AR session. When an experience is loaded using the **AR Light** feature, the associated light adjusts automatically based on the user's surrounding environment. This ensures that the virtual lighting always harmonizes with the real-world lighting, enhancing the immersion and visual quality of the AR experience.
