Methods

AggregateCullingParameters(ref ScriptableCullingParameters, HDCamera)

Use this method if you want to draw objects that are not visible in the camera. For example if you disable a layer in the camera and add it in the culling parameters, then the culling result will contains your layer.

Declaration

protected virtual void AggregateCullingParameters(ref ScriptableCullingParameters cullingParameters, HDCamera hdCamera)

Parameters

Type	Name	Description
ScriptableCullingParameters	cullingParameters	Aggregate the parameters in this property (use |= for masks fields, etc.)
HDCamera	hdCamera	The camera where the culling is being done

Cleanup()

Called when HDRP is destroyed. Allow you to free custom buffers.

Declaration

protected virtual void Cleanup()

CreateDrawRenderersPass(CustomPass.RenderQueueType, LayerMask, Material, String, SortingCriteria, ClearFlag, CustomPass.TargetBuffer, CustomPass.TargetBuffer)

Parameters

Type	Name	Description
CustomPass.RenderQueueType	queue	The render queue filter to select which object will be rendered
LayerMask	mask	The layer mask to select which layer(s) will be rendered
Material	overrideMaterial	The replacement material to use when renering objects
String	overrideMaterialPassName	The pass name to use in the override material
SortingCriteria	sorting	Sorting options when rendering objects
ClearFlag	clearFlags	Clear options when the target buffers are bound. Before executing the pass
CustomPass.TargetBuffer	targetColorBuffer	Target Color buffer
CustomPass.TargetBuffer	targetDepthBuffer	Target Depth buffer. Note: It's also the buffer which will do the Depth Test

Returns

Type	Description
DrawRenderersCustomPass

CreateFullScreenPass(Material, CustomPass.TargetBuffer, CustomPass.TargetBuffer)

Create a custom pass to execute a fullscreen pass

Declaration

public static FullScreenCustomPass CreateFullScreenPass(Material fullScreenMaterial, CustomPass.TargetBuffer targetColorBuffer = CustomPass.TargetBuffer.Camera, CustomPass.TargetBuffer targetDepthBuffer = CustomPass.TargetBuffer.Camera)

Parameters

Type	Name	Description
Material	fullScreenMaterial	The material to use for your fullscreen pass. It must have a shader based on the Custom Pass Fullscreen shader or equivalent
CustomPass.TargetBuffer	targetColorBuffer
CustomPass.TargetBuffer	targetDepthBuffer

Returns

Type	Description
FullScreenCustomPass

Execute(ScriptableRenderContext, CommandBuffer, HDCamera, CullingResults)

Called when your pass needs to be executed by a camera

Declaration

protected virtual void Execute(ScriptableRenderContext renderContext, CommandBuffer cmd, HDCamera hdCamera, CullingResults cullingResult)

Parameters

Type	Name	Description
ScriptableRenderContext	renderContext
CommandBuffer	cmd
HDCamera	hdCamera
CullingResults	cullingResult

Execute(CustomPassContext)

Called when your pass needs to be executed by a camera

protected virtual void Execute(CustomPassContext ctx)

Parameters

Type	Name	Description
CustomPassContext	ctx	The context of the custom pass. Contains command buffer, render context, buffer, etc.

Finalize()

Cleans up the custom pass when Unity destroys it unexpectedly. Currently, this happens every time you edit the UI because of a bug with the SerializeReference attribute.

Declaration

GetCameraBuffers(out RTHandle, out RTHandle)

Get the current camera buffers (can be MSAA)

Returns

Type	Description
RenderQueueRange	Returns a render queue range compatible with a ScriptableRenderContext.DrawRenderers.

RegisterMaterialForInspector()

List all the materials that need to be displayed at the bottom of the component. All the materials gathered by this method will be used to create a Material Editor and then can be edited directly on the custom pass.

Declaration

public virtual IEnumerable<Material> RegisterMaterialForInspector()
