Bug Type or namespace Universal does not exist in the namespace UnityEngine.Experimental.Rendering

Hello,

I've tried to install the Universal RP 10.4.0 on my Unity 2020.3.5f1 project, but for whatever reason it refuses to recognize the Light2D element from the UnityEngine.Experimental.Rendering.Universal namespace. Reason is stated because it can't find the Universal namespace.

I've followed the understated guide;
https://docs.unity3d.com/Packages/c...ersal@10.2/manual/InstallURPIntoAProject.html

Other steps I took;
Edit - RenderPipeline -> all upgrade possibilities
Edit -> Project settings -> Quality -. Set rendering to the UniversalRenderPipelineAsset
Edit -> Project settings -> Graphics - Set scriptable render pipeline settings to UniversalRenderPipelineAsset
UniversalRenderPipeLineAsset -> Renderer List -> Set 2D Renderer Data
Restarted Unity

I'm completely clueless and can't seem to find anything on the internet resembling my issue.
Does anyone have a clue?

 

I have a script where I made a flickering 2D light and this works for me in Unityv2019.3.5f1 with URPv7.1.8

Code (CSharp):

1. using UnityEngine.Experimental.Rendering.Universal;
2.  
3. public class FlickeringLight : MonoBehaviour
4. {
5.     public Light2D light;
6.     //[...]
7. }

Maybe they changed under what namespace Light2D is between v7.1.8 and 10.4.0? Like it might no longer be an experimental feature

if you just have the Light2D reference written without trying the using on UnityEngine.Experimental.Rendering.Universal, what does visual studio suggest for trouble shooting? (as in hover or right click on Light2D)
maybe visual studio is already able to tell you which using directive you need

 

The weirdest thing is that Visual Studio also suggests using UnityEngine.Experimental.Rendering.Universal and also seems to recognize the package, but as soon as I go back to Unity it first errors on the namespace Universal, followed by erroring on the type Light2D. The other option it gives is UnityEngine.Experimental.Rendering.LWRP, but it also instantly states being deprecated.

 

Code (CSharp):

1. using UnityEngine.Experimental.Rendering.Universal;
2.  
3. public class DayAndNightCycle : MonoBehaviour
4. {
5.         private Light2D light;
6. }

Errors from the get-go.

 

its really weird that it doesnt find the namespace at all...
I wonder, does it find
using UnityEngine.Rendering.Universal;

the 2DLight shouldnt be in that namespace but I wonder if it doesnt find any of the URP namespaces or just some

 

It doesn't find UnityEngine.Rendering.Universal either. Curious.

 

maybe try to remove the URP from the package manager and add it back again afterwards

 

Doesn't solve it either, i'm afraid.

 

Anyone has a clue? I'm looking to implement a feature on a deadline that suffers from this

 

I wonder... because you also mentioned it giving you the option of UnityEngine.Experimental.Rendering.LWRP...

Do you have LWRP and URP packages installed at the same time? I had that problem a bit ago, where I upgraded an old project that used LWRP to a newer Unity Version resulting in some packages being doubled, like LWRP and URP.
It did not cause namespace not to be found, but it resulted in some other errors being spammed in the console, untill I removed the duplicate packages from the package manager.
So if you have LWRP in the package manager aswell, uninstall that, its just the old name for the URP...

Beyond that I honestly have no idea what the problem could be

 

That might be possible, although I can't find it in the package manager. Is there any other place I can find installed packages?

 

Hello, was this ever fixed? I've got this problem now.
Although I don't know when it happened. I've opened a project from months ago, installed the new Input manager and it gives me this error. Although it may have happened before and I didn't notice, because it doesn't show up as an error in the console.

 

Hi, I've somehow managed to 'fix' this. Just go to your Solution Explorer in Visual Studio and expand the list of references. Scroll down to the very bottom. I had a few references which has yellow warning marks, as soon as I saw them the marks went away, and it worked again, very strange. Hope this helps.

 

I had this issue as well, the weird thing is if I added the namespace and just simply ignored the warnings, it works fine lol, the errors still show up. I fixed it by reimporting all assets. The above solution probably works just as well.

 

I fixed this error by recreating my .csproj files from the preferences and it added the URP references.

 

Using URP version 12.1.2, tried removing "experimental" from reference in script, so just:
using UnityEngine.Rendering.Universal;
and it works!, at least for version I'm using, can create vars in code of type light2d

 

it works thanks!

 

I had the same problem with Cinemachine. Reimport all scripts helped me

 

I had the same problem with the Light2D, other solutions could not help me (Unity 2021.3.0f1). Finally solved it by adding "Unity.RenderPipelines.Universal.Runtime" to my assembly definition. Then it let me add the "using UnityEngine.Rendering.Universal" for some reason.

 

Thanks - this worked for me.

 

Use namespace before class name like FunkyCode.Light2D instead of Light2D. And use .GetComponent<FunkyCode.Light2D>();

 

Thanks Blue_Flow.

Just had this annoying problem as well when trying to access the UniversalAdditionalCameraData.
Doing as you suggested made it accept the using statement (using UnityEngine.Rendering.Universal

 

Blue_Flow's suggestion worked for me. Thank you Blue_Flow!
