ProcessRenderRequests<RequestData>(ScriptableRenderContext, Camera, RequestData)

Implement this method in a custom Scriptable Render Pipeline (SRP) to execute render requests submitted using RenderPipeline.SubmitRenderRequest.

Definition

ProcessRenderRequests<T>(ScriptableRenderContext, Camera, T)

protected virtual void ProcessRenderRequests<RequestData>(ScriptableRenderContext context, Camera camera, RequestData renderRequest)

Parameters

context

ScriptableRenderContext
The context to render the request.

camera

Camera
The camera to render the request.

renderRequest

T
All the necessary destination information to render the request, for example render destination, mipmap level, slice index, and so on. This information varies based on the 
RequestData
type.

Remarks

Unity calls this method with the render pipeline when you call RenderPipeline.SubmitRenderRequest or Camera.SubmitRenderRequest. If you're creating a custom Scriptable Render Pipeline, you must implement this method and RenderPipeline.IsRenderRequestSupported to render requests outside of the Unity render loop.
See also: RenderPipeline.SupportsRenderRequest, RenderPipeline.SubmitRenderRequest.
