2D URP. Character silhouette behind the object

Hi all. Is there any way to implement a similar silhouette renderer https://docs.unity3d.com/Packages/c...ures/how-to-custom-effect-render-objects.html for 2D rendering?
I have custom Transparency Sort Mode axes so the character can overlap objects, but apparently Renderer Feature - Render Objects does not work with 2D rendering as needed.
I would like to either find out what the problem is, or find another solution to implement this effect.
The character I have uses bone animation and Sorting Group. There are also many objects in the scene that use custom shaders that can also make adjustments.
What options can you suggest?

 

Bump

 

I'd like to know how to do this aswell

 

Any update on this?

 

I think it's better to avoid unity's 2d renderer for the time being.

 

Maybe by now there is some way to make a silhouette with custom sorting in 2D URP?

 

Trying to figure this out myself with no luck. Disappointed to learn "Renderer 2D Data" doesn't support it. The example should really mention this clearly.

I think I switched to the "Renderer 2D Data" renderer for some of the lighting capabilities. Switching back to the "Universal Renderer Data" probably wouldn't work.

I tried stacking renderers to see if that could make it work; no luck.



I definitely have a lot to learn about the rendering pipeline. Feel like I am shooting in the dark. Also noticed differences between ShaderGraph "Sprite Lit" and the included "Sprite-Lit-Default" shader from URP/2D in terms of how they work with the scope of these different renderers.

Trying to learn more about how this works under the hood. Starting here: https://docs.unity3d.com/Manual/SL-CameraDepthTexture.html

 

If you have serious need for depth, like for a Depth of Field effect, you may be better off using standard URP and not the 2D Renderer. There's a depth texture checkbox on the 2D renderer asset, but it won't support certain effects.

 

Is there any documentation on what the 2D renderer does and doesn't support regarding the depth texture?

 

no. You can always read the source code (am doing this right now lol) by searching for Renderer2d.cs in "Packages" within your project. In comparison to UniversalRenderer.cs, it lacks a lot of depth stuff, no opaque pass.

 

Thanks for the additional insights Lo-renzo.

So what exactly does "no opaque pass" mean? Does that mean "AfterRenderingOpaques" Event won't trigger? Does that mean Filters using the "Opaque" Queue don't work?

Just tried: https://learn.unity.com/tutorial/custom-render-passes-with-urp, which is another tutorial published by Unity that shows off the render pass features, but I can't get that one to work either.

We REALLY need a render pass example that works and uses Renderer 2D Data and preferably a Shader Graph shader.

 

It does not do a separate pass over your opaque objects. In the UniversalRenderer.cs, it does the typical thing of an opaque pass followed by a transparent pass. In contrast if you put a URP standard Lit shader into a 2D Renderer scene, it won't look correct. It doesn't even generate a depth texture quite right. I think that's a bug. I had to fork the 2D renderer to get _CameraDepthTexture to work. You can check out Renderer2D.cs to see its passes. It's very simple, a few hundred lines.

The closest thing is a demo of a Kawase Blur pass in the 2D Renderer Samples project: https://github.com/Unity-Technologies/2d-renderer-samples/tree/21.2/Assets/Samples/2D Renderer/01 Feature Samples/09 Renderer Features

 

Is this on the roadmap at all or is there no plans to support it?
