New AssetBundle build system in Unity 5.0

According to Vincent's talk at Unite, both systems would coexist for a while at least, but the old way would probably eventually be removed.

 

Actually I did a test in the recent days, AssetBundle works with Sprite packer. The AssetBundle build pipeline can pick the right texture : the packed atlas or the original texture of the sprite.

One suggestion is you should set the sprites with same tag into the same AssetBundle, otherwise the atlas will be duplicated into all the related AssetBundles, just like the textures.

AND PLEASE do report any issue when you're using AssetBundle with sprite packer.

 

I would like to second the request of having the master manifest file (AssetBundleManifest) include a mapping of asset paths to asset bundles. With the new system as it stands, we will have to generate and maintain a separate manifest for this of our own creation. Otherwise we don't have a way to know which asset bundle to load an asset from at runtime.

 

@Vincent Zhang : I just tried adding my project to Unity Cloud Build(https://build.cloud.unity3d.com), my project is built completely relying on asset bundles from the very beginning.

I added a pre-build step to my build that runs BuildScript.BuildAssetBundles, and it succeeds.

I can't access the bundles though afterwards, the Cloud web portal only has links to the .unity3d file. Can you talk with the Unity Cloud people about giving access to all the results of the build??

 

Running into a couple different issues now. When I call this:

AssetBundleManifest manifest = BuildPipeline.BuildAssetBundles(buildDirectory, BuildAssetBundleOptions.UncompressedAssetBundle | BuildAssetBundleOptions.AppendHashToAssetBundleName, platformTarget);

My bundles are built successfully, but my manifest object will be null. Not sure what I have to do to get that back.

I tried to get around this by creating an AssetBundle from the directory manifest and loading the AssetBundleManifest object out of it. That works, but when I call manifest.GetAssetBundleHash(fileName), I get the same hash value for each of my bundles. The value is wrong and doesn't correspond to the value appended to the filename by BuildAssetBundleOptions.AppendHashToAssetBundleName.

Here's some sample output that I generated:

Hash of clientdata_hitfxgroupdata_80361b1b69d3dcdbd5e527712ec7d890.unity3d is 60ddbf5fff7f00000800000000000000
Hash of clientdata_locationdetailsdata_2d2af88976e81ec3fb330e55a78d7268.unity3d is 60ddbf5fff7f00000800000000000000
Hash of clientdata_missiondata_5249a7848ce44b3d70e4720ba7c02355.unity3d is 60ddbf5fff7f00000800000000000000

etc... The code spitting this out looks like this:

foreach (FileInfo fileInfo in buildDirectory.GetFiles("*.unity3d"))
{
string fileName = Path.GetFileName(fileInfo.Name);
Hash128 bundleHash = manifest.GetAssetBundleHash(fileName);
logger.InfoFormat("Hash of {0} is {1}", fileName, bundleHash.ToString());
}

The number appended to the filename agrees with the value in the .manifest file for that bundle, just not the one from AssetBundleManifest.GetAssetBundleHash(). I guess I could just parse it off the filename at this point, but that seems awfully fragile.

 

Could you please file a bug for it and let me know the bug id? Thanks.

 

I also have the manifest returned as null in most cases. Although it seems that the manifest file is created. I just don't get a reference returned from the Build Pipeline.

 

Could you please open a bug for it? Thanks.

 

A little more time with the debugger and I think the problem is that Hash128.ToString() is unreliable. If I use the debugger or reflection to get the private values making up the hash (m_u32_0, m_u32_1, etc), those values change appropriately and are consistent with the hash appended to the file name. However, calling ToString on the Hash128 object seems to produce unreliable results.

I'm going to try to repro these issues in the sample project and work on filing bugs for each of these issues this morning.

 

I was able to reproduce both of these issues in the sample AssetBundle project. In doing so, I noticed that BuildPipeline.BuildAssetBundles only returns null if there were no bundles that needed to be built on an incremental build (output is "No asset bundle needs to be rebuilt for this build."). I would still expect it to return the manifest in that case. I filed this as bug #672126

The Hash128.ToString() issue has been filed as bug #672131

 

Also added another one around removing a bundle from the project and that bundle not being removed from the manifest by an incremental build (bug #672147):

Incremental AssetBundle builds do not account for removed bundles if nothing else changed.

When building AssetBundles, if you remove a bundle from the project entirely, it will still appear in the manifest after an incremental build if there are no other AssetBundle changes to build. Removing a bundle should always remove it from the manifest in the next build, even if there are no other changes.

 

Thanks for reporting them, I'll have a look.

 

Yes, it's a bug. We will fix it.

 

as to API, is there way to build assetbudnled on linux enviroment? Basically to run dedicated linux server that can process assetbundling request? Somewhat like a cloud build?

 

ehh so sad Linux is best for cloud

 

I am running into an issue when trying to load my UI prefabs from AssetBundles. I am on RC2 and using LoadAsset to load the prefab. The error is this:

GameObject (named 'TitleScreen') references runtime script in scene file. Fixing!

These are fairly complex UI prefabs, and I've tried loading a couple different prefabs with the same result. I get that error once for each game object in the prefab with a MonoBehaviour on it. It doesn't really seem to matter what MonoBehaviour

These errors are preceded by several "The referenced script on this Behaviour is missing!" errors, but the prefabs don't have any missing behaviours before they go into the AssetBundle.

I see someone here has a similar issue: http://forum.unity3d.com/threads/assetbundle-loading-error.297663/

However, the indication in that thread is that there was an issue with LoadAssetAsync, but LoadAsset should work. Only it doesn't for me.

I have tried to reproduce this in the AssetBundle demo project, but haven't had any luck yet. I haven't submitted a bug because I don't have a good repro without sending along my multi-GB project. Perhaps someone at Unity has some insight into what condition causes this error to appear?

Thanks

 

I figured out that this only seems to happen if the AssetBundle is created through AssetBundle.CreateFromFile (not WWW). This allowed me to get a repro in the demo project, which I have submitted as bug #674181

 

Are asset bundles going to be in Unity 5 Free?

I ask because they are an important part of building collaborative games with community contributors

e.g. BlendSwap.org and various Blender communities, Autodesk 1234D and SketchBook communities and so on.

and also for selling advertising into one's game via inclusion of the advertising material in an asset bundle.

e.g. each year Ford makes available new vehicle models as advertising to be distributed via and are included viable and active asset bundles.

Of course the new networking features of Unity 5 will be crucial in that too.

Without assetbundles games will always be somewhat static and boring. They'll tend to be static imitations of those with deep pockets have to buy the market and not anything original.

I'm not suggesting this for my own benefit obviously, although I am too poor to afford all the Unity Pro or even one Unity Pro license, as a one man sporadic hobbyist I will always be extremely limited in using even what Unity Free already offers, but I'm suggesting it for the benefit of Unity as a company, their workers, and the potential for Unity to be used to built viable active game communities in comparison to the static game creation model now used.

Democratizing game development also means democratizing game content to be desirable from the perspective of the game players too. Minecraft didn't become popular based on a static game creation model; and LOL, my early enthrallment with the X System was primarily applying customizations to UI like I was applying makeup to an ugly computer monitor. Another computer date? Really? ;-P (just joking there, don't get too concerned)

 

Any time that I assign to assetImporter.assetBundleName the editor UI freezes permanently (RC2 & RC3). I have submitted a bug and Unity QA has confirmed repro.

Code (CSharp):

1. using UnityEngine;
2. using UnityEditor;
3.  
4. public class CrashyAssetImporter : AssetPostprocessor
5. {
6.     void OnPreprocessAudio()
7.     {
8.         assetImporter.assetBundleName = "foo";
9.     }
10. }

Is the new asset bundle system working for anyone? Is this not how it works? Is there a work-around?

 

I have been able to set that field successfully. However, I am doing it at build time and not in an AssetPostProcessor.

Code (csharp):

1.  
2.                AssetImporter importer = AssetImporter.GetAtPath(assetPath);
3.                 if (importer != null)
4.                 {
5.                     if (importer.assetBundleName != curConfig.BundleNameU5)
6.                     {
7.                         importer.assetBundleName = curConfig.BundleNameU5;
8.                     }
9.                 }
10.  

 

what happens to the materials?
version Unity 5r3

 

Case No.?

 

This new system seems to be working quite well for us. What I would like however is a way to set the bundle name of an asset programmatically. We sometimes generate data files for associated assets, and currently I'm having to parse the .meta files and print a warning if the fields don't match. Then the developer has to change the bundle manually.

This would also allow us to set the bundle name from the parent directory.

 

You can already do this.

Code (csharp):

1.  
2.                AssetImporter importer = AssetImporter.GetAtPath(assetPath);
3.                if (importer != null)
4.                {
5.                    importer.assetBundleName = "bundle name";
6.                }
7.  

 

Case No: 674894

New Project.
Add only the code in my comment above.
Import an audio asset -> UI locks up.

Interestingly, it's not a complete freeze. The [File, Edit, Assets...] menu still works. If you click the UI nothing seems to happen. But, if you minimize & maximize the window, then you will see the result of your click go through.

 

Thanks. Was looking in AssetDatabase class for this..

 

I don't think that's the problem. At least I hope it's not the case that OnPreprocessAudio happens after import and can trigger a reimport. Maybe you are thinking of OnPostprocessAllAssets. I have definitely stumbled into infinite recursive reimports using that one.

If I was continuously dirtying the file, I would expect my preprocessor to be run repeatedly. Instead, with this new and improved preprocessor:

Code (CSharp):

1. using UnityEngine;
2. using UnityEditor;
3.  
4. public class CrashyAssetImporter : AssetPostprocessor
5. {
6.     void OnPreprocessAudio()
7.     {
8.         Debug.Log("assetBundleName = [" + assetImporter.assetBundleName + "]");
9.         if (assetImporter.assetBundleName != "foo")
10.             assetImporter.assetBundleName = "foo";
11.     }
12. }

I get this for console output:

Code (CSharp):

1. assetBundleName = []
2. UnityEngine.Debug:Log(Object)
3. CrashyAssetImporter:OnPreprocessAudio() (at Assets/Importer.cs:8)
4. UnityEditor.AssetPostprocessingInternal:PreprocessAudio(String)
5.  
6.  
7. pAsset
8. UnityEditor.AssetImporter:set_assetBundleName(String)
9. CrashyAssetImporter:OnPreprocessAudio() (at Assets/Importer.cs:9)
10. UnityEditor.AssetPostprocessingInternal:PreprocessAudio(String)

And, that's it. No repeats. The "pAsset" line looks like it's from an Assert(pAsset != null); if I were to guess.

 

I'm having an issue with the new Asset Bundle system in Unity 5 Beta RC3. Now before i present my question, I've been working with this very project in Unity 5 since beta 17 (4 weeks ago), and everything worked perfectly fine loading several different scenes and all of their dependencies right up until i made a change yesterday that broke them.

So please, only answer this question if you are working with the new Unity 5 Asset Bundle system provided by Vincent Zhang on the unity forums. I will ask this question there as well.

So my project has 3 scenes, (loader.unity, title.unity, and rink.unity).
loader.unity is the only scene in the build settings, it is the first scene loaded. it has a single object in it that is marked for DontDestroyOnLoad. The loader object in that scene uses the LoadScenes script from the demo assets linked in this thread by Vincent Zhang http://forum.unity3d.com/threads/new-assetbundle-build-system-in-unity-5-0.293975/

It loads the second scene perfectly fine (title.unity) this scene just has a text field as a title for the project and a button to advance to the next scene.

when i press that button and load the third scene in the editor with "SimulateAssetBundles" turned on everything works just fine in the editor. and Everything worked fine up until yesterday as well.

Yesterday I got a new model from an artist for a new rink, i imported it into the scene and replaced a prototype i had built with ProBuilder since his was modeled in Maya and had perfectly accurate collision volumes and better materials.

This new model with new materials meant i had to adjust the lights in my scene, so I deleted the existing lights, and added 6 point lights similar to before, but different range and angle and intensity values.

Since there is high specularity on the ice material i wanted to see if i could add reflections, so i added reflection probes to the scene.

everything runs perfectly fine from the editor when i go from loader scene to title scene and play in rink scene and back to title scene. But when i do a build and it loads the rink scene i get this error in my logs and something strange happens.

Couldn't open the cache file! URL: file://D:/hockey/smashmouthhockey/SmashMouth/Smash Mouth Hockey_Data/StreamingAssets/AssetBundles/Windows/rinkscene

I've checked that nothing is accessing the file on my filesystem maybe keeping it read/write locked. I've tried completely whiping my project and re-pulling from Git and even cloning into a completely different folder on my computer so its definitely not a problem with no being able to find/read the file.

I've tried it on a second computer and still have the same problem and the problem also occurs in Web Player Builds as well as standalone PC.

Reinstalling Unity, deleting my library and reimporting all my assets, clearing web cache all has no effect.

I'm assuming that something in the lighting changes or the reflections broke the scene and some part of those settings aren't properly in the assetbundle file.

here's the full output.log

I wrote some test code about assetbundle system.
if attached some custom script component, unity report some red message when i load a bundle.
then I accidently make the referenced material a bundle, the error is gone.
I think it must be a bug.
