Which type of object is included in lighting calculations and batching optimizations?

• A. Dynamic objects
• B. Static objects
• C. Animated objects
• D. Kinematic objects

Answer: (B)

Static objects are the ones included in lighting calculations and batching optimizations because they don’t move or change geometry during gameplay. This stability lets the engine bake lighting into lightmaps once and reuse that precomputed lighting for performance. It also enables static batching, where many objects with the same material can be merged into a single draw call, reducing overhead.

Dynamic, animated, or kinematic objects move or deform, so their lighting can’t be pre-baked and they can’t reliably participate in static batching. They still render and can receive/cast lighting per frame, but they aren’t part of the baked lightmaps or static batching process.
