For example I provide one bundle with manifest Test.zip

[jleclanche]

Which game are those files from?

[jleclanche]

Can you send me musketeers_240083e70840140e8d06ed37cacbba13.unity3d as well as windows_5626cce8f12bc07aabffb1c6d07ea5b0.unity3d please.

[doterax]

Is from my game. I just want to know how Unity handles my bundles. And resources.

[doterax]

Can you send me musketeers_240083e70840140e8d06ed37cacbba13.unity3d as well as windows_5626cce8f12bc07aabffb1c6d07ea5b0.unity3d please.

Yep files.zip

[doterax]

I also provide you a manifest that describes bundle relations.

[doterax]

Hi, any news? You fix this issue?

[jleclanche]

Sorry, I can't look into this any time soon :/ but whenever I get back to this I'll take a look. Or maybe @ifeherva knows better.

[doterax]

You have any documents about Unity bundle structure? If I read may be I can help also.

[jleclanche]

Not really, documentation is nearly nonexistant. It's all reverse engineering work.

[ghost]

@doterax nah, I was mistaken :)

[Mactastic1-5]

UnityFS 5.x.x 5.5.0p4 is in header.

[doterax]

@Stellarspace so what?

[Mactastic1-5]

@doterax Is that even supported?

[robert-nix]

Some of these issues are fixed by 11c22bc. There are, however, still further issues reading some of the objects that I'll have to look into when I get more time.

[robert-nix]

After fixing the Object reading issue, there are two remaining errors here:

• unityextract can't handle the shader format introduced in Unity 5.5:

[Rademanc]

Hey. Yeah I am trying to export the shaders and having the same issues. Any luck with this?

[sebastientromp]

unityextract can't handle the shader format introduced in Unity 5.5:

I can confirm this issue is still there
