# CameraEvent and LightEvent events order reference for the Built-In Render Pipeline

> Explore the camera and light events you can use to schedule rendering commands at a specific time.

> **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/6000.6/manual/render-pipelines/universal-render-pipeline/introduction/installing-and-configuring-urp/upgrading-from-birp.md.md) and [Render pipeline feature comparison](/engine/6000.6/manual/render-pipelines/choose-a-render-pipeline/feature-comparison.md.md).

## CameraEvent

The order of execution for CameraEvents depends on the [rendering path](/engine/6000.6/manual/render-pipelines/built-in-render-pipeline/built-in-rendering-paths/rendering-paths.md) that your Project uses.

## LightEvent order of execution

During the "render shadows" stage above, for each shadow-casting Light, Unity performs these steps:

* [BeforeShadowMap](/engine/6000.6/script-reference/unityengine/rendering/lightevent/beforeshadowmap.md)
* [BeforeShadowMapPass](/engine/6000.6/script-reference/unityengine/rendering/lightevent/beforeshadowmappass.md): Unity renders all shadow casters for the current Pass
* [AfterShadowMapPass](/engine/6000.6/script-reference/unityengine/rendering/lightevent/aftershadowmappass.md): Unity repeats the last three steps, for each Pass
* [AfterShadowMap](/engine/6000.6/script-reference/unityengine/rendering/lightevent/aftershadowmap.md)
* [BeforeScreenSpaceMask](/engine/6000.6/script-reference/unityengine/rendering/lightevent/beforescreenspacemask.md): Unity gathers the shadow map into a screen space buffer and performs filtering
* [AfterScreenSpaceMask](/engine/6000.6/script-reference/unityengine/rendering/lightevent/afterscreenspacemask.md)
