What usually happens when Auto Generate in the lighting settings is enabled in Unity?

When Auto Generate in the lighting settings is enabled in Unity, lighting updates occur automatically without requiring manual control. This feature is particularly useful for developers because it streamlines the workflow by allowing changes to lighting data to be recalculated in real-time as adjustments are made. As a result, developers can see the effects of their lighting setups immediately, facilitating a more efficient development process.

The automation of lighting updates helps ensure that the scene's illumination is consistently maintained according to the current object placement and properties. This can be particularly beneficial during scene design when frequent adjustments are being made, as it removes the need for the developer to constantly trigger updates manually. While there are considerations regarding performance and potential visual inconsistencies during heavy editing, the primary function of enabling Auto Generate focuses on convenience and time savings during the design process.
