Hacking [release] GTX Extractor

[zachabossa]

how do i take texture out of newer smbw

 

[AboodXD]

Umm, the textures in Newer are LH compressed, decompress them, then open them using Puzzle Tileset Editor.

GTX Extractor v4.0 was just released!

Changelog:

• Added the ability to convert gtx files with multiple textures to multiple dds files.
• Added a new format: R4_G4_UNORM (LA4)

Feel free to report bugs, as there are no know bugs ATM.

Download.
Source code / Github.

It's actually funny that at 3.0, I said probably no more updates, but now we reached 4.0! XD

Here's a video showing the differences between v3.3 and v4.0:

Hi, I'm currently going through GTX Extractor (And BFLIM Extractor too, I'm just looking at in the Swizzle_BC part which seems to be the same throughout both), and am documenting all of my findings for my own project. Would you mind explaining, in AddrLib_computeSurfaceAddrFromCoordMacroTiled(), what a pipe and bank are? I'd greatly appreciate it.

 

[AboodXD]

If you really want a detailed answer, ask @Exzap.
The swizzle part is mostly his.

--------------------- MERGED ---------------------------

Feel free to ask me anything about BFLIM or GTX, but not swizzling.
Even I am inexperienced about swizzling, it was a nightmare until @Exzap came and helped.

--------------------- MERGED ---------------------------

BTW, your documentation says "For 0x31, the script uses the regular swizzle() function", that is wrong, it uses swizzle_BC(). (I think you figured out this later )

--------------------- MERGED ---------------------------

Also, the error "This type of BC compression is not equivalent to DXT compression!" is not relevant, it's a false error that I never bothered to fix.
That's why you should forget about BFLIM Extractor and focus on GTX Extractor and GTX files instead.

BFLIM Extractor is so incomplete to the point where it converts half of some images instead of the whole thing...

For example, "result = bytearray(dataSize)" should have been "result = bytearray(data)", so it would access the data directly and only swizzle the needed parts of the image. (Something like that, I'm terrible at explaining)

You see, this is later fixed in GTX extractor.

--------------------- MERGED ---------------------------

Also, it is OK for the swizzle value to be big.

Yep, I realized that later.

Yeah, I didn't realize that GTX Extractor was a thing until I was already making progress in the BFLIM script.

If you really want a detailed answer, ask @Exzap.

Thanks! He doesn't seem too active here so I'll send him a message on Reddit.

 

[AboodXD]

Yeah, so the swizzling function isn't from Decaf, but from Cemu. (Yes, I had some of Cemu's source code)

Also, it is OK for the swizzle value to be big.

I am really happy that you are making a cross-platform C++ QT project for Mario Kart 8! Is there a thread that shows you progress on the program, or is the google docs (besides twitter) the only place that shows your progress on the program?

Twitter would probably be the best place to follow progress. When/if I get textures to show, I'll put it on Github. When/if I get something useful to show with the FMDL, then I'll probably make a thread. However, since this is a very ambitous project, I'd rather not make a thread until then, because I don't want to make a bunch of promises I'm unsure I'll be able to deliver.

 

[AboodXD]

Good tool.
@AboodXD Aren't you interested in a bfres file?
Even if I'd like to do a texture hack, a renewal of a tool stops.
I'm in trouble because there are no tools which can be used in any bfres files.

I don't know if you've heard or not, but I made a tool for that, too.

 

[TheTechGenius]

I wonder if this would work with BOTW? Such as making the non dyeable armors dyeable, or maybe color them armors yourself, using this program.

I wish we could make our own armor and weapon mods, and use them in game. Like how Skyrim for PC has Weapons and Armor add-on mods. Now that would be awesome.

 

[AboodXD]

I think they use BFRES, and there's a tool for that in my description.

Also, yes, you can make your own armor, but it would need high ASM skills.

 

[AboodXD]

um im not sure what the issue is but

but something odd is happening(all the files should be more like 210 and 211.ddsnot this weird rotation stuff)
EDIT: included convert.rar which has a functioning dds and a unfunctioning dds and gtx's

Hi, your problem was fixed!

I'm going to release a new version soon.

 

[Zarklord]

Hi, your problem was fixed!

I'm going to release a new version soon.

oh cool!

 

[AboodXD]

oh cool!

If you could send me more examples, that'd be appreciated.

 

[AboodXD]

I'm going to release a new version soon.

Hey Abood, sorry for the bump.
I was reading through GTX-Extractor and I read that apparently it can extract .GSH files as well.

I tried to use it, but I cannot get the hang of it.
I am trying to extract 3 .gsh files at the moment, could you help me extracting these, please?
They're inside the .zip I uploaded.

 

[AboodXD]

Nope, it doesn't extract gsh files.
