Scene couldn't be loaded (AssetBundle has not been loaded) (1.2.2)

Hello,

I am stuck with a scene loading problem.

I have a special project with just my assets and scenes that are in a custom Unity Package (Package Manager)
and my main project that load these assets and scenes through the Addressable system.

One strange thing is that the assets and scenes that are in the Package subfolder in the Unity Project inspector does not have the "Addressable" checkbox. Why ?

So the loading and instantiation is working fine for the assets (Prefabs) but not working when I try to load an additive scene with the

Code (CSharp):

1. Addressables.LoadSceneAsync("SceneName", LoadSceneMode.Additive)

Before loading anything I use the download dependencies method to preload all my asset bundles.
And I can see each directory and files for each Addressable Group in the asset bundle cache location directory.
So they are well downloaded.

I have this error :

Code (CSharp):

Edit : The value returned by the InternalLoad method in the SceneProvider.cs file is null.

 

I found that if the scene is not in a package but in the main "Assets" hierarchy, it is working fine.
So this is definitively a problem with the UPM.

 

Oof! That sounds bad. Is this a regression or has it always been this way?

My project has UPM assets that are marked addressable but none of them are scenes... just prefabs, shaders, and the like.

Are you able to make non-scene objects in your unity package addressable, @JL_Tech_BBW ?

 

It is working fine with my prefabs that are in the package.
So it is maybe just a problem with scenes. (But maybe with other kinds of objects.)

 

Hey, I have run into the exact same problem when loading a scene with addressables. I am getting a "AssetBundle has not been loaded" error and I need to resolve this. Has this problem been solved? Addressables versions 1.7.4

 

+1 for same problem...

 

same for me when running on the iOS device (it's working fine on Android and in the editor).

"Scene 'Assets/MyScene.unity' couldn't be loaded because it has not been added to the build of the asset bundle has not been loaded. To add a scene to the build settings use the menu File -> Build Settings..."

I don't know it that's a beginning of a hint but the addressable name of the scene is 'MyScene' not 'Assets/MyScene.unity'

I use unity 2020.1.2f1 and Addressables 1.13.1

 

+1 Same issue for me with Unity 2020.1.16f1 (WebGL) + Addressable 1.16.15

 

I have the same problem. This is a bug report.
Please resolve it as soon as possible.

I found a solution!!
Setting "Internal Id Naming Mode" to "Filename" in the AddressableAssetGroup option will result in an error.
We have confirmed that changing to "FullPath" solves the error.

I hope this helps~

 

Another solution i found

Code (CSharp):

1. SceneManager.LoadScene(SceneManagement.GetActiveScene().buildIndex+1)

 

Yeah, I don't speak for the Unity team, but as a long time user I think it's fair to say, the addressables system is under heavy development at the moment (has been for over a year, reasonably, it's quite a big task).
It's officially released, but imho still unstable around the edges.

This thread is a prime example of a small option that doesn't always work as intended.
They refactored it, and on 1.16.16 it shows as "Bundle Naming" that should be set to "Append Hash to filename" in order to work on the build. (Thanks @Tochicopol for pointing that out, that helped me)
Alternatively, you can select multiple Addressables Groups, and in "Internal Id Naming Mode", set it to "Full Path", and in "Bundle Naming" set it to "Append Hash".
Why these options look different if you select one or multiple? Again, imho another hint that the system is under heavy development, and some things are still being refactored and fixed.

I set mine to "Filename" and it worked first time. However, I did another build, continued developing my stuff, and it stopped working.
So, I believe I was under the illusion that it worked, when in fact it was using a cached version when I had it previously set to append hash (which is the default initial value). Things like these are very hard to debug, so no wonder there are such issues still there.

PS.: When I say "doesn't always work as intended", I mean that maybe it's not even meant to work as we (devs) imagined. Every dev (person) thinks slightly differently, hence why documentation and samples are so important. Like, in a very hypothetical example, stupid me thought that "Include in Build" meant that it would include the addressable in the .apk, so I turned it off and was pissed it didn't generate my bundles. Then I read the tooltip and "oh, ok, that's not what they meant by 'include in build' "

 

Since this is in Addressables section I believe that this answer is missleading because you naturaly wouldn't want to include your scene in both Addressable AssetBundle and build.

@Tochicopol answer resolved an issue, however. Thanks!

 

I too have this issue when using this method while building out to IOS
Addressables.LoadSceneAsync("SceneName", LoadSceneMode.Additive)



Also the packed play mode for testing my AWS server where I hold the scenes is not preventing the loading of my scene even if I don't have my scene uploaded to my AWS bucket. I thought packed mode was supposed to load my scene from the server not Unity.


I agree that addressable asset system should receive more attention from the devs!

Could you please elaborate on this solution! screenshots are welcomed lol

 

Yo Trey this thread is super important to me and my team! I'd love to hear from the developers about the solution for loading scenes instead of prefabs for addressables (which is kind obviously an important topic). Please try to be more transparent on the status of the addressables bundles and also please put out more in depth tutorials on how to use them with firebase or AWS because thats what the people want!!!!

 

You select addressable group that is making you troubles, then in the inspector you expand Advanced Options section (it's colapsed by default) and under Internal Asset Naming Mode you select "Full Path" option



It should be set to that value by default, though.

 

Where did you guys get that image from -- you have to be a lot more transparent --DON"T ASSUME EVERYONE will KNOW where to find these ADVANCED OPTIONS. -- HOW + WHERE DID YOU ACCESS the SCREEN ABOVE EXACTLY!!! POINT by POINT.

 

Hey man, I feel your frustration, but no need for caps rage

If you've gone this far, you probably know how to create addressasble group and where it is, if not, you can follow any tutorial, that is the basic setup for addressables. You can also go through Getting Started section on unity docs. On the link, you can find how to access addressable group window. So when you select the group in group window, the standard Inspector window that you use for everything will show settings for the group, you'll find Advanced Options towards the end of the settings.

But, if you have not been changing this yourself, it should be already set to the desired options and you might have another problem.

Cheers,
Danilo

 

I have solved it by this method.

Select the scene which you want to add, click File-> Build Settings, go to "Scenes in Build" section and click "Add Open Scenes". The scene will be added.

 

Yeah, but an idea here is to exclude those scenes from build and then download/load them dynamically. If you tick that check box in Build Settings the scene will end up in build, thus defying purpose of using Addressables.

 

Just a small tip for those who may have reached here because of the

error for loading a scene from an assetbundle:
Make sure you do not add

Assetbundle.Unload()

before

SceneManager.LoadScene()

, You should load the scene first, then unload the bundle.
- best.

 

I am using unity 2019.4.29f1 and Addressable version 1.16.19. I am not getting this option in hierarchy. please help me with this. attached reference image

 

It might be because of the Addressables version. Can you update the packege or are constrained by Unity version?

 

it can be because there is to many spaces in a scene name

 

got it. removing answer

 

File -> Build Settings -> arraste suas cenas para ''Scenes In Build"

 

Problem still persists Addresssables 1.21.18 in Unity 2023.1.17

Internal Asset Naming is set to Full Path
Bundle Naming Mode set to Append Hash to Filename
I took out any special characters or spaces for the scene name but nothing seems to work
