Question Error message in URP project

I have started a new URP project, imported current Hybrid renderer (Version 0.51.1-preview.21) and followed the Moetsi-tutorial (which is a bit oudated).
The problem is, I cannot see the spawned entities (they appear in DOTS-hierarchy though and seem to have all relevant components). Instead the console contains this error:

Spoiler

A Hybrid Renderer V2 batch is using the shader "Universal Render Pipeline/Lit", but the shader is either not compatible with Hybrid Renderer V2, is missing the DOTS_INSTANCING_ON variant, or there is a problem with the DOTS_INSTANCING_ON variant.
UnityEngine.GUIUtilityrocessEvent (int,intptr,bool&)

This happens when the prefab is a standard Unity-sphere with default URP-Lit material. I created another material and checked "Enable GPU Instancing". Same error. Now I don't really know what else to do here. Is it so hard for Unity to convert it's own meshes and materials to properly work with their renderers? What am I supposed to do to show a simple sphere prefab in ECS? Any ideas?

Edit: This is especially confusing because the Unity instancing manual states:

When I verified that all requirements are met (target 4.5, DOTS_INSTANCING_ON,
UNITY_DOTS_INSTANCED_PROP) the shader is lacking the last one. And I'm quite unsure where I can add it, what to add and wether I can change built in shaders (or they are overwritten in any update).

 

Unity 2021.3.6f1 (Linux Editor) @ Xubuntu 20.4 (I know it's not officially supported, but had no issues).
URP 12.1.7 (was installed when creating the project via Unity Hub URP 3d template)
Hybrid Renderer 0.51.1-preview21
Entities 0.51.1-preview21
OpenGL 4.5 is shown in Unity window

Here is another thread with the same issue.

I'm going to purge (and reinstall) my system in the next 2 or 3 weeks. Maybe it works better with a clean install of everything.

Thanks for the hint. Do you mean "copy" or "move"? Won't that cause problems when the package exists twice?

 

Thanks for getting back with me Jussi.

I have tried applying different URP-shaders to the material and the message appears for all of them in play mode (and nothing renders).
When selected no message appears. However, When compiling the shader variants the process terminated after a while with following errors:

So maybe there is a problem with the urp shader(s) in vulkan?

Then I added a normal (non-ECS) sphere and it shows fine in playmode.

So maybe I find some time on the weekend to file the bug report and this issue can be fixed in a future version. Or is this futile as Xubuntu is not officially supported?

 

Do you using addressables ?
I have this error for asset loaded & converted from addressable but not for those who were in the scene and tag "Convert to entity"

 

No (at least not that I'm aware of). The tutorial I followed just created the sphere prefab from scratch.
May I ask wether you are on Linux too? Because for me the problem seems related to Vulkan. But whatever it is, the error message is too vague and misleading.

 

nop, win for me

 

Getting the same issues. On Windows 10. Created a new Project in 21 LTS, URP Template. Then added hybrid renderer package and then added a Plane to the Scene:

I also tried creating a custom shader graph, and am getting the same errors.

 

This invalidates the theory that the problem (if it has the same cause) is with Linux Vulkan shaders.

The error message is a bit unspecific. Maybe UT should make a unique one for each problem/issue. Would make it easier to diagnose and fix the problem on both sides. And I'm a bit worried that this happens with stuff provided by Unity (shaders, models, materials, project templates).

@Brainshack would you file a bug report? I'm not on an officially supported Linux distribution and fear that my report would be ignored because of that. You can link to this topic to show that others suffer from this too. Thanks.

 

@Brainshack: note that this message did NOT appear right away for me, but when I compiled the shader variants. So maybe try that and see if this happens for you too. Jussi refers to post #5.

 

So in short: Yes.

What I did was, copy the URP package to packages folder as described above and then try to compile the Lit Shader. However, after letting it run for over 45 minutes the compilation did not finish and I had to kill the Editor from Task Manager. After restarting then I got the error messages described above when clicking on the shader.

I just realized however that I was not using the latest LTS version. Was on .6 and now am updating to .8. Maybe thats helping.

EDIT: Updatiing to .8 did not change anything..

 

Not sure how I would report a bug?

 

Another small update:

I created a new project using 2020 LTS. Getting the same issue.

 

https://unity3d.com/unity/qa/bug-reporting

 

I reported a bug. For reference, the issue ID is IN-14089

 

As stated earlier, I tried creating a project in 2020.

Turns out I made a mistake when creating the project and it still was 2021 LTS.

In 2020 LTS I dont get the error, with the same version of the hybrid renderer.

My assumption is that it might be an issue with URP that was introduced in a later version? 2020LTS uses URP version 10, while 2021 LTS uses 12. @exiguous maybe you should give 2020 a try?

 

Thanks for bugreporting and verifying. But this was the second showstopperbug I encountered with a fresh project using ECS (first issue was fixed in latest patch). So I think I will give ECS some more time to "mature" and evolve and wait for 1.0. I just don't have time to waste with such issues. I understand when somethin goes wrong and it is my fault. But those bugs just kill a project since I can't fix them, can't work around them and as you see get no real "support" which enables me to proceed. And I don't even have "hardcore" usecases. Just using stuff coming with Unity. It's just disappointing and too buggy for me. I see people developing games and frameworks for ECS. So maybe the issue is still on my side. But as it is now it's just not my cup of tea.

 

Confirmed for me as well. I hit the same problem with the URP/Unlit shader in 2021 LTS but things are working in 2020 LTS with same version of the hybrid renderer package.
