Prepare for Content Update: Can't find any changed assets at all, how does this work??

I am able to build my first content into bundles. Then I build a player and try to edit some prefabs colors (ex. Change one cube to green). I try to click on "Prepare for Content Update" and locate a copy of my addressables_content_state that was used with the build. However, nothing is shown ever as different. That window always stays blank. I have tried to also completely change the prefabs, but still nothing shows up there as different.

How does this work? Has anyone ever gotten it to work? I tried following the same steps as the 2019 presentation video, but no luck. I also have mixed success with the Build Player Content. Sometimes, the materials don't get bundled.

Thank you

Changes not detected for us: Platform Switch, Profile Switch (this is not an asset change, but would require to rebuild a previously build changes for the next platform - copying the content state bin after each build to avoid overwriting is a workaround here). Changes to [Variables] profile variables ([UnityEngine.Application.version] -> changing the version is only updated once you restart the editor).

Changes to Adressable Asset Groups: Changing anything not directly to adressed asset, e.g. Adressable AssetReference[] => add/remove one entry is not detected

Where each entry is a Scriptable Object *.asset


The *.asset containing the SceneReference[] references is itself addressable. The SceneReference is a wrapper to hold addressable scenes.

Code (CSharp):

1.     public class SceneReference : ScriptableObject
2.     {
3.         [FormerlySerializedAs("Asset")]
4.         public AssetReference AssetReference;
5.         // other meta information, e.g public string Name;
6. }

The idea is to add a scene to an asset bundle via Content Update. No change to anything in that chain is detected by the addressable asset system Content Update Workflow.


Scenes holds only Addressable Scenes as there are many reports that mixing them breaks asset bundles. Scenes is static itself and set to pack separately. The scenes in there are referenced by SceneReference.AssetReference.

Essentially:

• UPDATE of an addressable is usually almost always detected. Changes to an adressables dependencies are usually detected if the dependencies are not addressable itself and are not ScriptableObject *.assets.
  
• ADD, REMOVE something to/from an Addressable Group or creating new groups or changing keys or changing labels is not handled correctly in all cases.

Changing assets: Changes in dependencies (e.g. changing a value from a referenced Scriptable Objects *.asset) is not detected.

Just to name a few. None of those is detected (static:true).

Have not tested more complex scenarios. As long as it fails to reliably detect changes to *.asset and AssetReference[] and ScriptableObject[] it is not usable for us.

 

@rachelgarza Thank you a lot and send some kind words to the team for us

 

One thing I've found out working through the Unity Bug Reports: You need to ensure dirty assets are saved (CTRL+S) before any change is detected. Therefore the following I've written above is not true and actually works:

• Changing the size of an Array of Scriptable Objects
• Changing the value of a scriptable object

Changes will not be detected until you press CTRL+S. However, once you saved the change, it will be detected.

 

I couldn't see the StaticContent update anymore.

 

I just found out that you guys changed to:
Can Change Post Release
Can't Change Post Release
That's so confuse for me

 

@locbh Thanks for pointing this out. I've been frustrated about finding out what is static and not, but you made me realize they relabeled it. It'd be nice if in the documentation they said this. @unity_bill Could you have someone update that in the docs? It's not obvious.
