What is the main reason for manually generating lights in a darker scene?

The main reason for manually generating lights in a darker scene is to improve player experience by enhancing visibility. In darker scenes, players may struggle to see important elements, navigate through the environment, or identify interactive objects. By strategically placing lights, developers can guide players' attention, create atmospheric effects, and ensure that gameplay remains engaging and accessible. Proper lighting can highlight key areas and help players orient themselves within the game world, making for a more enjoyable and immersive experience.

While adjusting graphics settings, turning off auto-generate lights, and ensuring art assets are imported correctly can all play roles in scene optimization and performance, they do not directly address the immediate player experience concerns that come with navigating a darker environment. The focus here is on the importance of visibility and player engagement, which is best achieved through thoughtful light placement and manual adjustments.
