[Soneoylys]

Are you on the latest version of AssetRipper?

Yes, I'm on the latest release of AssetRipper.

Which release are you using?

Windows x64

Which game did this occur on?

No response

Which Unity version did this occur on?

2018.4.7f1

Is the game Mono or IL2Cpp?

Mono

Describe the issue.

Some timeline failed to export with Unity 2018 (layout mismatched binary content (ArgumentOutOfRangeException)
This bug continues occurring during 0.2.x till now, on both Windows/macOS, other/older version untested.
I tried to omit this exception handler before, but the export still won't work.

If need any related files I can upload in here, but the complete game package is too big to upload.

Relevant log output

console output

Thank you for submitting your first issue here. Please be sure you have uploaded your AssetRipper.log file. It is in the same folder as the exe file. :)

Maybe is same issue as #698
If needed, I can try to trim down the game and upload here.

If those classes use [SerializeReference] attributes, this is indeed a duplicate of #698.

Anywhere I can confirm that?
Is that somewhere in recovered game project

Load the appropriate dll assembly into ILSpy.

Load the appropriate dll assembly into ILSpy.

Thanks, I searched in the csharp script, but seems there's no class using [SerializeReference]

Some Unity assemblies (correctly) do not get decompiled by AssetRipper, so searching the AssetRipper output is insufficient.

I did searched with exported script by ILSpy instead of AssetRipper result, still no luck
Or maybe I can upload trimmed game files (will be around 2GiB, or managed dlls only) here?

From what I can see, the issue is probably with PropertyName exposedName.

namespace Timeline
{
	public class TimeControlAsset : PlayableAsset, ITimelineClipAsset, IPropertyPreview
	{
		public ExposedReference<TimeControlBaseObject> Target;

		//Other content
	}
}

Seems like #511

[Soneoylys]

From what I can see, the issue is probably with PropertyName exposedName.

Thanks for reply, I'll go check if it is this case or not

PNG files are completely unrelated to this issue. If there's a problem with them, post a new issue.

Yes, the game script utilized PropertyName exposedName for timelines.

I'm kindly asking if any progress on this issue, I tried to backflash to #511 and seems the issue closed at commit "0d45e9de6aff91fcbf20ad67862e1555a9008329", but due to this part has been reflect for a few times like #227, so
it's sort of hard for me to debugging back those scripts to try resolve by myself.

[ds5678]

I haven't looked at it.
