Tool to compress/decompress texture *.ctxr from Shadow of the Colossus PS4

[Bánh Mì]

Could someone help me to decompression these files and then find a way to compress it back.

Tutorial how to post tools

Um, sorry, might be misunderstanding here, I'm just asking for some help, not publishing any tool.

ahh ok sorry 🙂 then not a problem

Seems like this tool works somewhat from what I tried just now with your samples.

CtxrTool GitHub

5 days ago was a new release coincidentally 😁

But probably isn't fully working as I have troubles displaying exported DDS files...

I am getting quite a few matches for different games Bluepoint worked on... I suppose the format may be somewhat different between games, but would suspect there is some form of overlap (mainly between entries that got released close together)

well, i tried that tool thou, even created an issue, but seems like its not the same format, but hey, thanks you for the efforts!

In years of trying as every new development on any game related to Bluepoint has been made, I have not made any progress with models or textures for this one. No doubt it's possible, but nobody with the ability has ever actively worked on tools for it, so chances of there ever being any are slim to none at this point.

it template 010 for .ctxr (decompressed) file.

and i shared my tool for decompress all file compressed

Might be redundant, but since I saw this thread existed and in case people get confused, a lot of the work on this game has been handled here: 

 

and a link to my tools which handle these can be found here in the Releases page with full source https://github.com/Shadowth117/Aqua-Toolset

This tool supports SOTC, Demon's Souls PS5 (and ps3, though that's a different format) models and textures as well as MGS HD Collection .ctxrs. I looked at 360 for MGS HD Collection, but it seemed like they did something pretty different and much more obtuse. It DOES work for the more recent Master Collection ports of 2 and 3 after some tinkering to handle 64 bit, little endian versions of the format. 

Anyways, that should be more than enough for people to have fun with, so enjoy.

Yes, I have used your tool to export DDS from the files, but my goal is to edit and import them back into .ctxr for localization purposes.

Okay well, first of all, you actually don't need to do the Oodle compression on the textures. BluePoint did that on most, but notably not all files and each file has something in the footer that denotes if it uses compression. If you REALLY want to compress it anyways, you can look at how that works here: https://github.com/Shadowth117/PSO2-Aqua-Library/blob/98d7b1a00a4a78fcd8b4344ad918f96f24b1015d/AquaModelLibrary.Data/BluePoint/CompressionHandler.cs#L5

I don't really know why some files have a 6 and some have an 8 there, but it is what it is. 50/50 on if that would work, but again you don't need this for what you're doing. 

You would however need to reswizzle your data, reformat it, and then throw the BluePoint metadata around it, though there's a lot of unknowns. You can check my source and figure that out if you want, but my advice would be resave the data to same pixel format and size, then stuff it back in over the original data after swizzling. https://github.com/Shadowth117/PSO2-Aqua-Library/blob/98d7b1a00a4a78fcd8b4344ad918f96f24b1015d/AquaModelLibrary.Data/BluePoint/CTXR/CTXR.cs#L111

Since you're likely to just be editing ui textures you probably won't even have to worry about mipmaps which makes this a bit simpler for you. 

I might look into this game again when it can emulate passably, but for now, there's what I know. I don't think you'll find a ton of research on this specific version of the format out there past what I have, unless I overlooked something. There's the Metal Gear BluePoint stuff above, but that's very old and is functionally entirely divorced from what got used in Shadow of the Colossus's PS4 remake and beyond besides the file extensions.
