Close| context | The context to render the request. |
| camera | The camera to render the request. |
| renderRequest | 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. |
Implement this method in a custom Scriptable Render Pipeline (SRP) to execute render requests submitted using RenderPipeline.SubmitRenderRequest.
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.
