almost all .xbm files contain only a small preview image. the rest textures are in content?\texture.cache.
here are a couple of scripts to extract the data — https://github.com/hhrhhr/Lua-utils-for-Witcher-3 , needed Lua 5.3 and lua-zlib.

some maps from game (extracted, merged from tiles, cropped and optimized):

String files came with the release of the game. Anyone has any info on how to approach the new w3strings format?

The .redscripts format is also different from the .w2scripts format.

edit: Someone make a repacker for .bundle files please.

I think that the files are very simple, but the contents is just xor-ed. look at any br.w3strings, inside there is almost clean text (UTF16 with some html tags).

I think that you are using the wrong Lua. try to test:

Code: Select all

> lua -e "print(_VERSION)"
Lua 5.3
> lua -e "print(string.unpack('<L', '\xD2\x02\x96\x49'))"
1234567890      5

Odd, I have 5.3 installed. I get the same error with your test.

"<L " means "native sized little endian unsigned long". maybe you are using a big endian or/and 16-bit platform?

let's try one byte:

Code: Select all

lua -e "print(string.unpack('B', '\xFF'))
255     2

That works.

I am running Fedora 64bit on virtualbox.

I can only advise to try all conversion options from here (http://www.lua.org/manual/5.3/manual.html#6.4.2) with string "DXT1", for example, find inoperative and inform maintainer of lua package.

Well, it even fails on their demo page.

Very annoying.

use "<I4" instead of "<L".

Ahh, that seems to have done the trick!

This does work, but the files that come out aren't valid dds files.

edit---

Ahh, needed to change <L below too.
