Which setting determines how many lights can affect each object?

• A. Shadow Distance
• B. Global Illumination
• C. Per Object Limit
• D. Quality

Answer: (C)

In forward rendering, the engine caps how many lights can influence a single surface to keep shading calculations affordable. The Per Object Limit sets that cap for each object. Up to that number of lights will contribute to the object's shading; any additional lights beyond the limit won’t affect the object's surfaces in real time (though they may affect other objects or rely on baked lighting, probes, etc.). This is a direct way to balance visual fidelity with performance: more lights per object means more shader work and slower rendering, while a lower limit speeds things up but can change how the object looks under multiple lights. The other settings control different aspects—Shadow Distance affects how far shadows render, Global Illumination handles indirect lighting and bounce, and Quality governs overall fidelity and performance—so none of them specifically set the number of lights that can affect an object. For example, if you have ten lights around an object but the per-object limit is four, only four lights will influence the object's shading.
