Official 2D Renderer in Universal Render Pipeline in 2019.3

As a small side-note to my previous post, it appears there is a typo in the in-line help for Camera Sorting Texture.
Note how in the image "Layers" is plural, but every place else I've seen reference to this it is not.


That could cause some confusion.

 

I tried it checked and unchecked and every other way I could think of. It just doesn't seem to be picking up the _CameraSortingLayerTexure.

I even created a brand new URP project and tried with that. Still nothing.

 

FYI, I created a bug report for this issue and attached a very simple project that shows the issue.
Find it here: https://fogbugz.unity3d.com/default.asp?1321997_b2jfjm4k0fr29eiv

 

Thanks @eduardooriz. Currently I can't see your image.

 

My current setup seems to be very similar to yours and I feel like it is setup correctly. I have checked and double checked everything many times. Is it possible to download this sample you have? I'd like to see if it works for me.

 

Here is a l link to the sample project I sent with my Unity Bug Report.

This is a simple URP project with 2D Renderer. (Unity 2021.1.b11)
It has 3 Sprites. One to act as "Water" and 2 that sit behind the water and show the distortion effect.

For me, I get no distortion. It just acts as though the _CameraSortingLayerTexture does not exists as a global shader variable.

Here is the link (from my One Drive account): https://1drv.ms/u/s!ArCOhzCNfm7ckOtJST9p0A3ChjeiSg?e=PMziLM

 

Hmmm. Ok, I'll try again on my end and report back. Thanks for taking the time to look at this.

Oh, and to be clear. You think this should be work-able with Sprite Unlit as well.... if setup correctly? The scene in my game is mostly Unlit.

 

An update for anyone else struggling with this.

I have everything working now. (Thanks @eduardooriz)
After a lot of tinkering I found that Sprites and the Water shader can indeed be Unlit... with a caveat.

In order for the _CameraSortingLayerTexture to work... even for UnLit sprites and shaders graphs, you HAVE to add at least one light. What is interesting is the light doesn't need to have any sorting layers set and its intensity can be set to zero.

Here is the only light in my game (My game is all Unlit). This was added just to make the _CameraSortingLayerTexture work:



Note the target sorting layer is "None" and intensity is 0.

My only thought is that having this light in the scener triggers something internal to make the _CameraSortingLayerTexture start working.

Hope this helps someone else.

I tried using the 2D renderer, and two problems with it. One, I can't apply a skybox to it. Two, each time I pan around in the scene view, some weird trail comes on my image (a picture of this is below). However, But, when I used a Forward Renderer instead, everything worked perfectly and fine.

 

Oh nevermind. Using the forward renderer meant that I couldn't use 2D lights.

 

THANK YOU!!!
I have been trying to figure this out for 3 days now. As someone not so experienced with programming or shaders, I had no idea if the bug was my fault or something on the pipeline not working. It is working as it should now. Working on 2020.3.0f1, upgraded to 2020.3.1f1 but is still wouldn't work, until you mentioned adding that light.

 

@Chris_Chu I just noticed that the 2D Renderer and the 2D Lights don't have the "Experimental" tag anymore in 2021.1. But the scripts still seem to be in the Experimental namespace. So, is the 2D Renderer production-ready now?

 

Since there is no Experimental tag anymore, will the 2D renderer work for me? Because I have been having that trail issue and that I can't apply a skybox...

 

One question @Chris_Chu , would it be so problematic to put the Falloff Offset property of the Freeform lights back? There are effects that I don't know how to achieve without that property that has been removed in 2021. For example: https://forum.unity.com/threads/fal...m-lights-effect-not-possible-anymore.1082441/

 

If I apply a skybox the trail still appears. So I removed it (because you said the 2D renderer doesn't support a skybox), and the trail effect doesn't show up anymore.

So I think that fixed the problem

 

Isn't this really confusing? You removed the "experimental" suffix, so now it looks like it's production-ready. If I didn't come here to ask I would've just assumed that it's out of experimental status.

 

Agreed. Removed experimental when it's still experimental.

 

Thank you so much for your explanation, you are very kind. So, for me to understand it properly, are you saying that the Falloff offset property is going to reappear in the future, once you make the fix you mention?

And Bonus question: Based on what you describe, could the Falloff offset property be enabled for Freeform lights only, so it does not produce wrong results with other types of light like Sprite lights?

Thank you again.

 

Oh, so I take it the URP 2D Renderer is still experimental after all... Any (ballpark) idea when it will be considered production-ready?

Thanks

 

I really hope they fix shader graph bugs before considering it being *not* experimental anymore.

 

Hi guys, sorry for insisting but is there anything you can tell us in advance about this? I have to make some important decisions soon and some of them depend on whether we will have a replacement for this visual effect in the future or not (whenever it comes, I don't need a date). Thank you.

 

Hi!
I was wondering if the Emission integration to the Sprite-Lit Shader Graph as been planned for upcoming releases? Even an approximation would be appreciated. I can't see it in the road maps and we would really need it to reach the visual target of our project.

Thanks a lot!

 

3 month passed since the URP lighting got broken for shader graph created shaders. Any updates on that one? Would love to update my project to 2021 but without a workaround or fix, I can't upgrade.

 

More than a year has passed since I've been told that Depth of Field for 2D renderer and 2D objects will be on the roadmap... :/

Any news ?

Thanks !

 

That may work, yes.
It's not perfect since it forces me to create a sprite that fits perfectly the shape of the light, which takes much more time, but it's something. Freeform with falloff offset would be the perfect solution.

 

Thanks for the quick reply Chris,

That would be nice =)
We've been waiting so long for this, DOF is so important for non pixel-art games !

 

Sure thing. I've submitted a new bug report case 1330228 for you. This time with 2021.1.3f1 and with URP 11.0. Let me know if you need any other info from me.

 

Saddened that the depth mesh branch was closed. Was looking forward to those improvements to fill rate by utilizing depth testing as well as improvements to to the tessellation. I am disappointed with progress on the 2D renderer for over a year of development. It feels like dev has been super slow on improvements, changes, and getting out of preview. Not sure what the priorities are internally but cancelling perf improvement workflows seem like a poor choice from the outside.

 

Need the depth mesh branch very much to improvements to fill rate !! My game is very very slowly in mobile! Because I have many layer of sprites.

 

And when the new features in unity 2021 like "Camera Sorting Layers Texture" can be used in 2019? My game is developing in unity 2019.

 

What's the plan for shadow caster 2d and tilemaps? Right now if I add a ShadowCaster2D to a Tilemap it will use the bounds of the tilemap to create shadows instead of using the individual polygons that make up the tilemap. I can create separate ShadowCaster2D game objects and manually fit their polygons to the tilemap. That is not a feasible solution. I've seen some workarounds but I don't know if I want to support any of these in a production game.

 

I guess you already know about this https://forum.unity.com/threads/script-for-generating-shadowcaster2ds-for-tilemaps.906767/
But I agree, that should be built-in already.

 

I do. Thanks for figuring that out. That might be the saving grace for using Unity on my next project. It would be nice to tell my boss that this is just a temporary workaround.

 

Is there still no way to control the length of the shadows cast by 2D lights?

 

Thanks so much Chris for your reply. We do need the normal maps, so we're looking forward to that next version you mentioned. Would you happen to have the target version number?

 

Thanks again so much for the replies Chris! We will check the release notes of 2021.2 and this thread.

We encountered another serious issue in 2021.1 : the 2D lights seems to have the Normals settings always resetting.
https://forum.unity.com/threads/2d-spot-light-normal-maps-always-reset-to-disabled.1052687/
We are having that issue in both 2021.1.3f1 and 2021.1.5f1. It was fine in 2020.3.6f1.
I see the "Bug" tag on this, but no one from Unity confirmed it's going to be fix, is it planned?

Update :
On the issue with 2D Lights normal setting reset, is seems fixed in 2021.2.0a17

I've added falloff offset back to v2021 in my fork @Chris_Chu . It works as intended. Would it be possible to do the same in the official version or is there any potential problem I'm not aware of?

Hi @Chris_Chu, is there any news on the integration of Emission to the Sprite-Lit Shader Graph? Is it confirmed to be in 2021.2 once out of alpha?

Thanks so much for your time!

 

Trying to implement Camera Stacking on a 2020.1.7 2D Render Pipeline project. I know it wasn't possible in earlier versions of the URP, but from URP 8.2.0 this message in the docs has been removed, making me believe it has been made possible

"Important note: In this version of URP, Camera Stacking is not supported when using the 2D Renderer or when using the VR Multi Pass mode. Support for these will be added in upcoming versions of URP."

https://docs.unity3d.com/Packages/c...nes.universal@8.2/manual/camera-stacking.html

I've been unsuccessfull so far, and curious if the mistakes are on my end, or if the docs are incorect = it still isn't possible for the 2D render pipeline in URP 8.2 ?
