Update: UE Viewer is fully compatible with LNII; Static/SkeletalMeshes, SkeletalAnims, textures and materials work fine.

That's nice, but what's the AES key?

Got an issue with the full game, happens on the tail end of exporting the 'Game' folder.

Code:
assertion failed: NumBones < MAX_MESHBONES

CSkeletalMesh::SortBones: NumBones=3373 <- CSkeletalMesh::FinalizeMesh <- USkeletalMesh4::ConvertMesh <- USkeletalMesh4::Serialize <- LoadObject: SkeletalMesh4'SKM_Arena.SKM_Arena', pos=A14A0D, ver=518/0 (unversioned), game=ue4.24 <- UObject::EndLoad <- LoadWholePackage: /Game/Environment/Objects/Transmission/AreaSpecific/BossFightDestruction/SKM_Arena.uasset <- ExportPackages <- CUmodelApp::ShowPackageUI <- Main: umodel_build=1487

@Grendor: Umodel build from Godfall topic should work with such meshes.

Extracting textures & such works like a charm. Thanks so much!

But has anyone figured out how to get the audio? It's strange because everything in the "Audio" folder is just 1 kb in size and won't extract properly. Since those files are so small (even the ones identified as background music), I doubt they actually contain the sounds themselves. (I assume they're data files that simply trigger when the sounds play, or something.)

Looking through the different folders and files though, I don't find any larger files that appear to contain the actual audio. I'd love to get the music that wasn't included on the soundtrack! Anyone else figured this out?

Hey, have somebody found the maps, or things like that, like the wilderness map in UE Viewer?
If yes, PLEASE tell me, I've been trying for HOURS...

UE Viewer does not seem to show the audio file formats. You can use UnrealPakViewer to view all of the files in the archive. You'll have to use the Base64 decryption key, which is "bbicgJabL1USpcoYNxR+2zFECru2A7/gmTpwSec/alQ=" (minus quotes). The music files are located in the Helios/Content/WwiseAudio folder. You can convert the wem files to ogg or wav using vgmstream.

Sorry if I sound like a dumb newbie here, but do I need to compile the UnrealPakViewer CS file into an executable? I'm not having much luck putting it to use.
I've worked with VGMStream plenty in the past, so that part's familiar. UPV is just a new one to me.

Thanks for your prompt response and help anyhow! I appreciate it.

No, you don't have to compile it yourself. You can download the release from the right side of the page, or here is the direct link:

I REALLY REALLY want that audio file when Mono enters the tv but that clip is NOT in the Helios/Content/WwiseAudio folder (trust me i went through the 402 wem files 5 times already) but I found this in Helios-WindowsNoEditor\Helios\Content\Audio\Events\Objects\Electric\TVs\TV_Teleport. Is anyway to unpack this? I tried importing them in Unreal Engine, with UnrealPakViewer, UE model and nothing worked. Can someone how to dive into this files?
