So, MTA seems to store most of it's UI textures in .CBTEX files.
Looking at them in a hex editor shows that they are probably BNTX(A standard switch texture container)

It's definitely compressed data, but can it be decompressed?
That is my question.

There is other compressed formats in the game(CBFMD, CBNTX etc etc), and there is a decompression script for them.

But apparently these CBTEX files use different compression.
Just thought i'd mention that too.

Here's a sample CBTEX:

And a sample CBNTX for comparisons sake:

sadly some of those texture files uses a different format that RTB is unable to figure out, just like the cubemaps since they're pretty much BNTX textures.

Different format?
How would we know if the format is different if the data is compressed?

If the CBTEX stuff can't be decompressed, can the CBNTX and CBFMD files be re-compressed?

As in different texture type that is unknown and not documented, so getting them to export properly isn't pretty much a top priority to researchers.

there's no tool to re-compress or rebuild the files.

Fun fact, 2.3.0 has a portion of GZip compressed CBTEX . It's waluigi_all_alb_l.cbtex and more.

SimonTime figured out the compression! https://github.com/simontime/MarioTenni ... compressor

I don't think recompressing with 0x50 is necessary as some files are compressed as of updates with only deflate, making the game handle multiple compression types over one primary, meaning you likely could use modified deflates over modified 0x50s for any 0x50 file.

CBVFX: Compressed Binary VFX (NW_PTCL)
CBPTL: Compressed Binary ParTicLe (NW_PTCL)
CBFMD: Compressed Binary CaFe MoDel (BFRES)
CBTEX: Compressed Binary TEXture (BNTX for Switch)
CBNTX: Compressed Binary NX Texture (BNTX, Switch ONLY).

New compression was added as of updates, I'll say them later.
