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

CameraEvent

The order of execution for CameraEvents depends on the rendering pathThe technique that a render pipeline uses to render graphics. Choosing a different rendering path affects how lighting and shading are calculated. Some rendering paths are more suited to different platforms and hardware than others. More info
See in Glossary that your Project uses.

Deferred rendering path

• BeforeGBuffer: Unity renders opaque geometry
• AfterGBuffer: Unity resolves depth.
• BeforeReflections: Unity renders default reflections, and Reflection ProbeA rendering component that captures a spherical view of its surroundings in all directions, rather like a camera. The captured image is then stored as a Cubemap that can be used by objects with reflective materials. More info
  See in Glossary reflections.
• AfterReflections: Unity copies reflections to the Emissive channel of the G-buffer.
• BeforeLighting: Unity renders shadows. See LightEvent order of execution.
• AfterLighting
• BeforeFinalPass: Unity processes the final pass.
• AfterFinalPass
• BeforeForwardOpaque (only called if there is opaque geometry that cannot be rendered using deferred): Unity renders opaque geometry that cannot be rendered with deferred rendering.
• AfterForwardOpaque (only called if there is opaque geometry that cannot be rendered using deferred)
• BeforeSkybox: Unity renders the skyboxA special type of Material used to represent skies. Usually six-sided. More info
  See in Glossary.
• AfterSkybox: Unity renders halos.
• BeforeImageEffectsOpaque: Unity applies opaque-only post-processingA process that improves product visuals by applying filters and effects before the image appears on screen. You can use post-processing effects to simulate physical camera and film properties, for example Bloom and Depth of Field. More info post processing, postprocessing, postprocess
  See in Glossary effects.
• AfterImageEffectsOpaque
• BeforeForwardAlpha: Unity renders transparent geometry, and UI(User Interface) Allows a user to interact with your application. Unity currently supports three UI systems. More info
  See in Glossary Canvases with a Rendering Mode of Screen Space - CameraA component which creates an image of a particular viewpoint in your scene. The output is either drawn to the screen or captured as a texture. More info
  See in Glossary.
• AfterForwardAlpha: BeforeHaloAndLensFlares: Unity renders lens flaresA component that simulates the effect of lights refracting inside a camera lens. Use a Lens Flare to represent very bright lights or add atmosphere to your scene. More info
  See in Glossary.
• AfterHaloAndLensFlares
• BeforeImageEffects: Unity applies post-processing effects.
• AfterImageEffects
• AfterEverything: Unity renders UI Canvases with a Rendering Mode that is not Screen Space - Camera.

Forward rendering path

• BeforeDepthTexture: Unity renders depth for opaque geometry.
• AfterDepthTexture
• BeforeDepthNormalsTexture: Unity renders depth normals for opaque geometry.
• AfterDepthNormalsTexture: Unity renders shadows. See LightEvent order of execution.
• BeforeForwardOpaque: Unity renders opaque geometry.
• AfterForwardOpaque
• BeforeSkybox: Unity renders the skybox.
• AfterSkybox: Unity renders halos.
• BeforeImageEffectsOpaque: Unity applies opaque-only post-processing effects.
• AfterImageEffectsOpaque
• BeforeForwardAlpha: Unity renders transparent geometry, and UI Canvases with a Rendering Mode of Screen Space - Camera.
• AfterForwardAlpha
• BeforeHaloAndLensFlares: Unity renders lens flares.
• AfterHaloAndLensFlares
• BeforeImageEffects: Unity applies post-processing effects.
• AfterImageEffects
• AfterEverything: Unity renders UI Canvases with a Rendering Mode that is not Screen Space - Camera.

LightEvent order of execution

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

• BeforeShadowMap
• BeforeShadowMapPass: Unity renders all shadow casters for the current Pass
• AfterShadowMapPass: Unity repeats the last three steps, for each Pass
• AfterShadowMap
• BeforeScreenSpaceMask: Unity gathers the shadow map into a screen space buffer and performs filtering
• AfterScreenSpaceMask
