Edit: Maybe this helps you out a bit more. https://forum.xentax.com/viewtopic.php?t=15904

But that is extracting the audio, and I already knew about that. The point is being able to compress them efficiently - of which I don't think is possible without extensive work since the banks are already compressed.

BTW, no need for any toolbox, can extract fsb from bank using QuickBMS.

Some unity asset bundles (inside StreamingAssets folder) can be compressed using XTool with unity engine plugin. Not all can be, so do check this first.

If there's any Wwise Audio (.wem /.bnk) or fmod banks (.bank) then use rz - I recommend MTX with RZ thanks to BLACKFIRE69. You won't get much compression out of these banks.

Obviously on bigger Unity games like Kerbal Space Program there's a lot more assets which can be compressed in different ways, but srep+lolz is the easiest method for Unity Games.

Thank you for the answer.

And what about UE4 and *.pak file? XT+srep+lolz?

Some games on UE4 have encrypt .pak files and need AES keys + UE4DT for decrypt. Then xt+srep+lolz

Hmm... That's interesting... How can I tell if the specific .pak file is encrypted?

If it compresses badly (or doesn't precompress into a larger size).

Could someone tell me what's the best compression method applicable on FOR HONOR (.forge files)..

I am almost newbie, and can't find AFR method inside UltraArc GUI...

Thanks

Thanks

you can use a batch(Pack.bat) file or Conversion Example for the compression with DiskSpan instead of UltraArc....

Hi
Does anyone know of a good method for AO Tennis 2?

The game does not compress very well in it's retail state and doesn't use a common engine like Unreal Engine or Unity.

There's nothing that GFS can detect, so it's unlikely that precompression can be used here.
