Question What is best practice for full-screen blit?

Hi. I found that URP's full-screen blit code is quite different between the best practice on document and actual implementation.

For example, you can find that Blitter.BlitCameraTexture() is recommended method for blitting in online document:
https://docs.unity3d.com/Packages/c...rsal@14.0/manual/customize/blit-overview.html

But FullScreenPassRendererFeature.cs in URP used

Code (CSharp):

1. CoreUtils.SetRenderTarget(cmd, cameraData.renderer.GetCameraColorBackBuffer(cmd));
2. CoreUtils.DrawFullScreen(cmd, passMaterial);

Also, document says that SetupRenderPasses() should be used for storing cameraColorTarget:
https://docs.unity3d.com/Packages/c...iversal@14.0/manual/upgrade-guide-2022-1.html

But FullScreenPassRendererFeature.cs uses "cameraData.renderer.GetCameraColorBackBuffer(cmd)" directly in its execution method.

So what is correct best-practice?

Thanks.

 

@Kichang-Kim have you found a solution?

 

Unfortunately, no. So I used document's recommendation:
https://docs.unity3d.com/Packages/c...rsal@16.0/manual/customize/blit-overview.html

 

It constantly changes and thus is not easy to suggest one solution as is per Unity version.

Better start on the upcoming RenderGraph version if want to be future proof, as this is the latest version.

They also promised not to change this one, though i give this around zero chance
