What is a major characteristic of baked lights in a game environment?

• A. They dynamically adjust to moving objects
• B. They cast shadows on all game objects
• C. They do not cast shadows when objects move through them
• D. They are only for outdoor environments

Answer: (C)

Baked lights are a lighting method used in game environments that involves pre-calculating the lighting effects and storing them in texture maps. This characteristic allows for highly optimized performance by not requiring real-time calculations for lighting, which can be computationally expensive. When baked lights are utilized, they provide static lighting information, meaning they do not respond to changes in the scene, such as moving objects. As such, if a dynamic object moves through an area lit by a baked light, it will not cast shadows or interact with the baked lighting in a way that reflects those changes. This leads to the characteristic where baked lights do not cast shadows when objects move through them, as the lighting information has already been established and is unchanging during runtime. This static nature of baked lights allows for greater performance efficiency since the game engine does not have to calculate lighting in real-time, but it limits the realism of interactions between lights and dynamic objects. Hence, the primary characteristic of baked lights is that they do not respond to the movement of objects within the scene.
