Unity 5.3 - Objects in scenes loaded from AssetBundles are losing their STATIC flag

Unity Engine
1

I am currently on Unity 5.3.1p1 and encountered an issue when loading scenes from AssetBundles.

I have noticed that when loading a Scene from an AssetBundle, all of the objects in that AssetBundle Scene lose their STATIC flag.

The way I am loading the Assetbundle is with SceneManager.LoadSceneAsync but the issue also happens when using the non-async method. The issue also occurred when using both LoadSceneMode.Additive and LoadSceneMode.Single as well.

The AssetBundles are uncompressed and target the Windows Standalone platform.

Has anyone encountered this issue? I was able to reproduce this on an empty project.

Anyone able to reproduce this issue?

It doesn’t seem to fixed in Unity 5.3.1p2 either.

3

I have just tried again on Unity 5.3.1p3 and it’s still not fixed.

When my scene loads from the Asset Bundle, all the objects from the Asset Bundle load without their STATIC field checked!

Is there anybody out there…?

Can anyone else reproduce this bug?

I just found this bug too. It is the first time that I’m working with AssetBundles so I thought i did something wrong, but it seems that it just doesn’t work.

When you use the assetbundleManager from Unity (http://unity3d.com/learn/tutorials/topics/scripting/assetbundles-and-assetbundle-manager?playlist=17117) and activate simulation mode everything seems to be fine, but it doesn’t work when you are really loading the bundles…

Yes, I have also noticed that if I load my levels from the Scene files instead of loading them from the AssetBundles, the STATIC flags remain correct when loaded.

So this issue only happens when loading scenes from AssetBundles.

Confirmed 5.2.4f1

Confirmed 5.3.4f1

Update: the reason we noticed this in the first place is because we were getting incorrect lighting and other lighting-based artifacts. Thought maybe it was because of the static being unchecked in bundles, but it wasn’t - turns out it was that we were loading the scenes from bundles as additive, instead of single - once we made them single, the artifacts were fixed. So, not sure if you were seeing any issues from this bug other than potentially performance problems if static batching isn’t working properly, but that is how we solved our particular issue - performance hasn’t been too bad of a problem for us…yet. :wink:

I would like to bump and confirm this issue. We have a game that loads all the levels as asset bundles and are put into an empty scene (additive) When the level is loaded we get these errors:

  • Failed opening GI file

  • Failed loading probe set data for hash

  • Error adding system: Data not available

The light map and light probes seem to be working fine even though it tells me they couldn’t be loaded.
Furthermore all of our static prefabs have the “static” flag turned off, which we think might be creating some performance issues because the static batching is not being taken advantage of.

Guys, if you want a bug to be fixed, you need to create a bug report, not post on the forums.

11

Did anyone report a bug ? I’m still having this problem with unity 5.5.1f1. Not only from a bundle, also having problems with built-in scenes.

12

5.5.3 lost the static flag buy i can see the mesh combine and the frame Bug see the staitc batch maybe inspector bug ~~someone said can use StaticBatchingUtility

13

Manually set isStatic = true, and then use StaticBatchingUtility.Combine trigger combine after at least one frame.

14

Summary error.It should after at least one frame when instantiate the gameobject，not set the property.
