# Lighting

> Understand how to light your application and compare the different lighting options in Unity.

> **Important:**
>
> The Built-In Render Pipeline is deprecated and will be made obsolete in a future release.
>
> It remains supported, including bug fixes and maintenance, through the full Unity 6.7 LTS lifecycle.
>
> For more information on migration, refer to [Migrating from the Built-In Render Pipeline to the Universal Render Pipeline](/engine/6000.5/manual/render-pipelines/universal-render-pipeline/introduction/installing-and-configuring-urp/upgrading-from-birp.md.md) and [Render pipeline feature comparison](/engine/6000.5/manual/render-pipelines/choose-a-render-pipeline/feature-comparison.md.md).

With Unity, you can achieve realistic lighting that is suitable for a range of art styles.
