MLB The Show Nintendo Switch and PS4 textures

[lorak]

The attachment has two folders, one with sample textures from MLBTS 22 PS4 and the other one with textures from MLBTS 25 Switch. In both cases, the texture files are in txt files. I assume that all those textures are compressed as I cannot see any reasonable shape in texture finders.

Hopefully some of you can help me to extract these textures from those two systems.

Looks like multiple textures with some records in the header that are 352 bytes wide. e.g. UNIFORM.TEX:

I agree it looks like the .TEX files uses some variable length compression.

The "GLOVEINFIELDER_L01.0.PS4" is interesting with 16-byte blocks, but none of the usual BC* formats are turning up anything recognizable.

I agree, the length of header of the Switch files seems to be 0x160 (352) bytes. By the way, in the header of the Nintendo Switch files we find the following in little endian:

offset 0x10 File size, minus header size (0x2720 bytes for the Switch version).
offset 0x14 Number of files.

Inside each texture header, move 0x144 bytes from the start of the header to find the offset of the texture itself.
For example, for "jersey-color" go to offset 0x173 and for "numbers-color" go to offset 0x854 to find 0x2720 and 0x1f9a0.
Those offsets tell us where each data texture starts respectively.
For the PS4 files, all this information should be located in another place.

The problem is to decompress those textures.

This file seems to be the 3D model for the glove infielder not a texture.

Detected PS4 format compression LZ4 + PS4 swizzle. Used comp type scan.

I will try to write bms.

Here's some info.

I am too lazy write bms.

Thanks for sharing this info, I just reading your message. Did you check the Nintendo Switch textures too? 

[h3x3r]

Yes but it's terrible compared to ps4. Still investigating...

EDiT:

Well compression is same, LZ4 at switch + switch swizzle.

Here's template for switch version.

Not sure where is PixelFormat variable.

Many, many thanks.
