Right, so I'm trying to make sense of Fable 2's texture files and they seem to be compressed.

The header files are stored in a separate archive bnk, even though the texture files I've seen have a lot, if not all of the header data in them. Dimensions, crucially, are there in the first 20 or so bytes.

According to this post by Tosyk https://forum.xentax.com/viewtopic.php?t=4571#p39375 the tex files are lzma:192k compressed (although I'm not sure how they found this out as I can't get 7zip to tell me anything.)

Thing is, and I might be trying to do something wrong here, I cannot find a straightforward way to decompress/inflate the texture files so that I can see what they are, using 7zip or any other tool I can find.

Could it be a quirk of the bnk extractor that dumps the texture files without decompressing them?

Any help/input very gratefully received!

But the size is bullsh!t Also there is no decompressed size. I can only see compressed size at 0x8 offset. "191904" big endian.

Turns out they're encrypted as well, at least partially.

Included more .tex files and corresponding headers, extracted from different .bnk archive.
