Class ScriptableRenderer

Class ScriptableRenderer implements a rendering strategy. It describes how culling and lighting works and the effects supported.

A renderer can be used for all cameras or be overridden on a per-camera basis. It will implement light culling and setup and describe a list of ScriptableRenderPass to execute in a frame. The renderer can be extended to support more effect with additional ScriptableRendererFeature. Resources for the renderer are serialized in ScriptableRendererData.

he renderer resources are serialized in ScriptableRendererData. ScriptableRendererData ScriptableRendererFeature ScriptableRenderPass

Methods

ConfigureCameraTarget(RenderTargetIdentifier, RenderTargetIdentifier)

Configures the camera target.

Declaration
public void ConfigureCameraTarget(RenderTargetIdentifier colorTarget, RenderTargetIdentifier depthTarget)
Parameters
Type Name Description
RenderTargetIdentifier colorTarget

Camera color target. Pass BuiltinRenderTextureType.CameraTarget if rendering to backbuffer.
RenderTargetIdentifier depthTarget

Camera depth target. Pass BuiltinRenderTextureType.CameraTarget if color has depth or rendering to backbuffer.

EnqueuePass(ScriptableRenderPass)

Enqueues a render pass for execution.

Declaration
public void EnqueuePass(ScriptableRenderPass pass)
Parameters
Type Name Description
ScriptableRenderPass pass

Render pass to be enqueued.

Execute(ScriptableRenderContext, ref RenderingData)

Execute the enqueued render passes. This automatically handles editor and stereo rendering.

Declaration
public void Execute(ScriptableRenderContext context, ref RenderingData renderingData)
Parameters
Type Name Description
ScriptableRenderContext context

Use this render context to issue any draw commands during execution.
RenderingData renderingData

Current render state information.

FinishRendering(CommandBuffer)

Called upon finishing camera rendering. You can release any resources created on setup here.

Declaration
public virtual void FinishRendering(CommandBuffer cmd)
Parameters
Type Name Description
CommandBuffer cmd

GetCameraClearFlag(CameraClearFlags)

Returns a clear flag based on CameraClearFlags.

Declaration
protected static ClearFlag GetCameraClearFlag(CameraClearFlags cameraClearFlags)
Parameters
Type Name Description
CameraClearFlags cameraClearFlags

Camera clear flags.
Returns
Type Description
ClearFlag

A clear flag that tells if color and/or depth should be cleared.

Setup(ScriptableRenderContext, ref RenderingData)

Configures the render passes that will execute for this renderer. This method is called per-camera every frame.

Declaration
public abstract void Setup(ScriptableRenderContext context, ref RenderingData renderingData)
Parameters
Type Name Description
ScriptableRenderContext context

Use this render context to issue any draw commands during execution.
RenderingData renderingData

Current render state information.

SetupCullingParameters(ref ScriptableCullingParameters, ref CameraData)

Override this method to configure the culling parameters for the renderer. You can use this to configure if lights should be culled per-object or the maximum shadow distance for example.

Declaration
public virtual void SetupCullingParameters(ref ScriptableCullingParameters cullingParameters, ref CameraData cameraData)
Parameters
Type Name Description
ScriptableCullingParameters cullingParameters

Use this to change culling parameters used by the render pipeline.
CameraData cameraData

Current render state information.

SetupLights(ScriptableRenderContext, ref RenderingData)

Override this method to implement the lighting setup for the renderer. You can use this to compute and upload light CBUFFER for example.

Declaration
public virtual void SetupLights(ScriptableRenderContext context, ref RenderingData renderingData)
Parameters
Type Name Description
ScriptableRenderContext context

Use this render context to issue any draw commands during execution.
RenderingData renderingData

Current render state information.
