Astral Chain package

[Demonslayerx8]

I've got the container pretty much all figured out, but I have 0 clue on how to make a script, so I've uploaded some samples from the game for anyone to make a BMS script for

0x00 - magic [pkzl]
0x04 - unk
0x08 - package size
0x10 - files in package
0x14 - table offset location
0x18 - length of filename table

table:
-Filename Location (at ZStandard)
-Decompressed Size [this can be skipped]
-Offset location of said compressed file
-Compressed file length

No need to extract files to their decompressed files since it's all zstandard/zstd compression, I can just decompress them via smash ultimate tools, which is what I did for the model, when I was extracting files 1 at a time without proper filenames.

So which tools did you used?

Extracted the compressed files via hex 1 at a time, then I used zstd (via cmd prompt) to decompress the files.

Atm just waiting for a proper script to be made that'll extract all the files with their proper names in their compressed forms.

This QuickBMS script should extract and decompress the files.


# Astral Chain . pkz extract

IDString "pkzl"

ComType ZSTD

Goto 0x10
Get ITEMS Long
Get FILE_ENTRY Long

XMath NAME_TABLE "FILE_ENTRY + (ITEMS * 0x20)"

For A = 1 to ITEMS

Goto FILE_ENTRY

Get JUNK Long
Get ZSIZE Long
Math NAME_OFFSET + NAME_TABLE
Goto NAME_OFFSET

Clog FILENAME OFFSET ZSIZE SIZE
# Log FILENAME OFFSET ZSIZE # Use this line to get compressed output instead

Math FILE_ENTRY + 0x20

Next A

ooohh thanks!! Works on all the files so far!

The model/animation format is identical to Nier's. Texture format is unknown to me.
I added support for Astral Chain to my noesis plugin. If someone can help me with the texture format (FOURCC is "XT1\x00") I should be able to add it to the plugin.

Note that you need to unpack the pkz files by yourself.

the texture format is ASTC_10x10_UNORM and uses switch's swizzle algorithm. Still working on it.

WTA :
magic
unk [possibly file version?]
file total
table1 offset
table2 offset
table3 offset
table4 offset
table5 offset

table1 - texture offset locations in wtp
table2 - texture filesize in wtp
table3 - unk
table4 - unk
table5 - texture header info

Edit:
Also, is there a reason why there's no facial bones for the 2 main chars? Or do they use vertex morph sets?

In other platinum games there are seperate head models elsewhere (sometimes even other package) that have full rig. Probably the same here.

Table 3 are flags for the game
Table 4 are hashes to reference textures in materials

ah gotcha

ohh, didn't know that, thanks for the tip.

Edit:
Well so far I have no luck with getting these textures properly, it's close but I don't know much about swizzling.

There are volume textures in sta/ra_00.dtt, maybe they can give you some insight about the unknown texture info fields. I am trying to match them to https://github.com/aboood40091/BNTX-Inj ... globals.py but for now I am rather unsuccessful. I was hoping it was some kind of BNTX that had been stripped.
The texture archive is in wtb format (meaning the texture data is inside the file rather than in an accompanying wtp).

I took a look, and they're about the same as the regular texture

the flags however, makes a bit more sense to me now
20000060 - normal/pbr/special maps
20000064 - diffuse/cube

Did notice that the cubemap and FogLUT has unk4 set as 8 tho... as far as I know, cubemaps have 6 layers, not 8...


edit:
if u wanna see/take a look at the coding for these textures in Switch Toolbox

[Kerilk]

unk4 could be:
typedef enum {
T_1D,
T_2D,
T_3D,
T_Cube,
T_1D_Array,
T_2D_Array,
T_2D_Mulitsample,
T_2D_Multisample_Array,
T_Cube_Array
} texture_type_t;

so 8 would be T_Cube_Array
But that could be completely wrong.
Also the textures from CubeMap have 7 mip map, while those from FogLUT have 1, but sizes don't seem to coincide:

Well so far, no luck on getting these textures properly.. I've tried contacting RTB, but no response yet.

Edit:
Could the 2nd unknown after depth be bytes per pixel?

I was working through the file format on my own and worked out all of pkz and most of DAT file structure but I couldn't figure out what the 5th table was for in DAT files and it seems maybe unneeded? The first 4 were for offsets, file type, file name, and size, but I couldn't for the life of me figure out what the 5th was. Any one got any ideas?

Also I have 010 templates for pkz dat, and wip templates for the texture ones as well but don't have too much on textures yet. Will post when I get home later
