Help with chunzstd.

Post by mita996 » Wed Oct 10, 2018 10:50 pm

Friends, I've extracted FIFA 19 Nintendo switch and got chunzstd. compressed files. Is there anybody who can help me with this?

Here's a BMS decompressor for the zstd-compressed rx3 image container.
RX3Decompressor.zip
The pixel formats look weird so I didn't add the unpacking code.

Well there's indeed a small issue in the code where the script trys to read past the end of the file. But QuickBMS didn't consider it an error? Might just be lucky. It's fixed now in v0.1.2 script.

here is Noesis python script to open the decompressed rx3 file. :D
tex_FIFA19_Switch_rx3.zip
supports dxt1, dxt5 and ati2, top level mip only.

Buddy, there is a strange thing, I've decompressed other fifa's like fo4, and the files are perfect (512 kb) for hair for example and the textures are bright. These files are 684, and they are shiny.
for example, the second image is the correct one, ignore resolution of the image: https://i.postimg.cc/7Zmpd2tB/image.png

Accidentaly, I made a mistake in tipping, I can't decompress, even with the updated script:
- 0 files found in 0 seconds
coverage file 0 0% 8 146611 . offset 00000008

Press ENTER or close the window to quit

the one on the left is dxt5 likely with alpha layer and the one on right is dxt1 no alpha likely.
the dxt5 image is probably being displayed with the alpha layer overlay which dulls the look. :)

also, the original rx3decompressor bms script decompressed both your samples in this thread fine,
make sure you using latest version of QuickBMS always. :D

Thank you guys :) :). I was using old quickbms, that's why I got error. Is there a way how can I fix those alpha layers, so they look perfect and not dull?

Nice work Ace! :D

Alright this is made just for fun — or if anyone feels it helpful — an rx3 unpacker/convertor to pvr format preserving all mipmaps:
RX3Unpacker.zip

Since BC5 encoded pvr images won't load by my PVRTexTool I'll save also the raw data as an rx3l file.

I don't have the texture file you're talking about. But the results of the two in this thread look fine to me.

No, there's no actual convertion between different pixel formats. All data is taken from the file directly, but a pvr header is added.

you can convert dxt5 to dxt1 easily with Photoshop and Nvidia's texture tools.
