Re: A Hat in Time

OK. In my free time I'm working on support for A Hat in Time.

I fixed the USkeletalMeshes and UAnimSets.

However I'm stumped at UStaticMesh.

Apparently FStaticMeshLODModel3 has some data appended to it.

It's not a problem when I have one LOD, but it crashes on multiple LOD.

Here's my question.

Where to find that struct in IDA?

PS: Size dif between serialized single LOD data and stopper is 133 B. Even then I'm not sure if that's variable.

Where to find that struct in IDA?
It's hard. The chain of findings is roughly this:

1. Find UStaticMesh constructor, it's linked to "StaticMesh" string with UClass::UClass.
2. Find class VMT (virtual method table).
3. Find Serialize method in VMT.
4. Recognize basic functions, e.g. TArray<UMaterialInterface> serializer, etc.
5. Compare code in IDA with e.g. UModel's UStaticMesh::Serialize code, find where LODs are serialized - in assembly.

And so on ...

And unfortunately I'm not that versed in assembly.

I'll soon post what I have so far as fork.

Which fork is yours?, that link is to the main github and there are 221 forks.

Is your fork for a specific version?, if so then which?

I have tried it with the current version and it has errors with animations, static meshes and skeletal meshes.

@09williamsad: Not sure what you're using, since 305 build is like from years ago. Try this compiled build of SlawekNowy's fork with UE3 -> "A Hat in Time" override.

Thanks, that one works on all but the static meshes

Judging from posts above and the fork commits, static meshes were never fixed there. It's still a great work nonetheless.
