ScriptableRenderPass.Execute and "RenderWithShader"

I want to render the scene object UVs using a specific shader and Camera.RenderWithShader to write that result to a render texture but NOT actually change the image on screen. My intention is to use the results in the render texture as a property in a material in a subsequent render pass where I will create the final image.

I get an error stating that recursive rendering is not supported in URP which makes sense but then how else am I supposed to achieve this?

Here is a link to what I basically want to achieve using the old school "OnRenderImage" callback: https://github.com/khalladay/Pencil...etch/Assets/Scripts/PencilSketchPostEffect.cs

I'm trying to do this the "URP" way with just one camera and multiple render features but now I'm just stumped due to lack of documentation and threads about Scriptable Render features.

 

SRP api doesn't support "RenderWithShader"

 

I gathered as much. Do you have any suggestions on what I should do?

 

Anyone have any suggestions?

Obviously this can be done without render features already, but I want to understand how this can be done purely with URP render features so that I don't have to manage the messiness of two different rendering APIs when making effects.

 

Not exactly sure if this is what you want but

ScriptableRenderContext.DrawRenderers

combined with

DrawingSettings.overridematerial

maybe?
