HDRP post process

How does one post process using HDRP. Previously it was OnRenderImage. I see RenderPipeline.beginFrameRendering but is there an equivalent for post processing? Or do I have to define a RenderPipeline.Render from my script?

I haven’t checked it out thoroughly but this may help you get started:

@teutonicus thanks I was looking at his TestbedHDRP but his samples weren’t loading. This one seems more approachable and I’ll check it out.

If anyone else has more guidance, much appreciated!

Based on that sample to do a post process effect:

GetComponent().customRender and define your custom render function, in that HDUtils has BlitQuad.

The documentation is confusing…

I guess com.unity.render-pipelines.high-definition and UnityEngine.Experimental.Rendering are different beasts?
