Hi, so a while ago (back in april) I used to be able to extract models from a game called The Isle on steam. However, now it keeps giving me this error upon extraction and I have no clue what it means.  

assertion failed: Pos >= 0 && Pos < Info->UncompressedSize

FPakFile::Seek <- UnPackage::SetupReader <- LoadObject:SkeletalMesh4'SK_Allosaurus.SK_Allosaurus', pos=1018, ver=510/0 (unversioned), game=ue4.15 <- UObject::EndLoad <- LoadWholePackage:SK_Allosaurus <- CUmodelApp::ShowPackageUI <- Main:umodel_version=624


Any help would be appreciated, thank you.

Please try umodel.exe from this page:
https://github.com/gildor2/UModel/commits/master/umodel.exe
It has many versions, try "Commits on Oct 1, 2017".
If you're having troubles understanding how Github Web interface works, here's a direct link to THIS version:
https://github.com/gildor2/UModel/raw/97055ff8d9cee50e400853868bea90f8dcde3730/umodel.exe

Please let me know if this will work for you.

Hello, thanks for the response. I'm still getting the same error however, so I tried overriding with a newer version of UE4, now I'm getting this error

Code:
Serializing behind stopper (1E9A+4 > 1E9A)
FPakFile::Serialize <- TArray::Serialize:0/4 <- TArray::Serialize:0/2 <- USkeleton::Serialize <- LoadObject:Skeleton'SKEL_Baryonyx_Adult.SKEL_Baryonyx_Adult', pos=2B88, ver=513/0 (unversioned), game=ue4.17 <- UObject::EndLoad <- LoadWholePackage:SK_Baryonyx <- CUmodelApp::ShowPackageUI <- Main:umodel_version=621

I'm not sure what's wrong since a few months ago I was able to extract the files perfectly. Did the game become unsupported after a certain update? Is that even possible?

There are all UModel.exe versions in that list on Github. If you could get down and find a version which worked fine, this may help me to identify the problem (will greatly save my time).

"Commits on Apr 9, 2017" is the umodel version that used to work for me. It was right when UE4 4.16 was added and I could extract the files just fine using 4.15.

Understood. So, this is mid-air engine again.

I'm still unable to extract the files, but nevermind. The game probably became unsupported.

I believe you found the UModel version which still supports this game, isn't it?

Ah then it's a misunderstood. I found the Umodel version that used to work with the game, but it suddenly stopped letting me extract files for some reason. Probably after a certain update that made it unsupported.

Sorry, I didn't understand. Old UModel worked with The Isle. After some update (when I've supported release version of the game engine) UModel stopped working. 2 weeks ago you found the UModel version which still worked with the game. What's now? Did you occasionally lost the UModel which worked (I believe NOT) or the game got an update breaking compatibility with OLD UModel?

The game got an update breaking compatibility with the old Umodel as well. No version works now.

Whenever I try to extract using UE 4.16+ I get this error:

Serializing behind stopper (2082+4 > 2082)
FPakFile::Serialize <- TArray::Serialize:0/4 <- TArray::Serialize:0/2 <- USkeleton::Serialize <- LoadObject:Skeleton'RexSubadult_Skeleton.RexSubadult_Skeleton', pos=2DB2, ver=514/0 (unversioned), game=ue4.18 <- UObject::EndLoad <- LoadWholePackage:SK_Albertosaurus <- CUmodelApp::ShowPackageUI <- Main:umodel_version=634

And when I try to extract using UE 4.15 (which used to work before) I get this:

assertion failed: Pos >= 0 && Pos < Info->UncompressedSize

FPakFile::Seek <- UnPackage::SetupReader <- LoadObject:SkeletalMesh4'SK_Albertosaurus.SK_Albertosaurus', pos=1031, ver=510/0 (unversioned), game=ue4.15 <- UObject::EndLoad <- LoadWholePackage:SK_Albertosaurus <- CUmodelApp::ShowPackageUI <- Main:umodel_version=634

This means that the game gets updates to the engine, so making any special changes to umodel for it could be broken in the future.

Just checking if anyone has had any luck in extracting the models recently. I can view the texture and static assets but not able to view any skeletal meshes.


******** Loading object Skeleton'SKEL_Acro_Adult.SKEL_Acro_Adult' ********
