So recently i got my hands on XenobladeX (or Xenoblade Chronicles X if you want).
I almost figured out model format, but textures are not my cup of tea, they have different pixel formats and different extensions but in the core they are all same. I'm curious now about standard format used for models.
See? The color is here, but segments are placed randomly in raster.
This is supposed to be DXT1(BC1) format.
Right texture is dumped from CEMU.
Textures have MTXT header (I believe Castlevania used those too), the funny thing is, the header is backwards and at the end of file.
Thanks for any info. Samples below.
Important information: this site is currently scheduled to go offline indefinitely by end of the year.

Re: XenobladeX mtxt texture format
Im not sure, but can this be stored in Morton (aka Z) order?
ATM I don't know what texture format WiiU adopted, so it looks like blind shot.
EDIT: After some more research I found this little program called texconv2, it may be answer to my question, the file seem to be gtx format, now I just need to find header for gtx and it should work.

Re: XenobladeX mtxt texture format
ok so if Xenoblade is a WiiU game then the texture is likely gx2 (or gtx?) format, your samples are probably gx2 image data with a custom header, or footer in this case.
texconv2 can supposedly convert gtx to dds as posted here
http://zenhax.com/viewtopic.php?t=534
there is a Noesis python script by Zaramot that calls texconv2 to convert gtx image data here
viewtopic.php?p=103731#p103731
looks like there is some pretty good python 3.4 source code here for unswizzling etc

someday i would like to be able to use this in a script to eliminate having to use any tool called by the script

you meant 112 instead of 122 right?PredatorCZ wrote:Code: Select all

Re: XenobladeX mtxt texture format
Thanks for post Ace, I have finished converter months ago, so its fine.
Since Xenoblade 2 will use same engine I will test my tool and probably release it to public.

Re: XenobladeX mtxt texture format
i put together a Noesis python script for fun to open your mtxt sample
to make this work
extract tex_XenobladeChroniclesX_WiiU_mtxt.py to Noesis\plugins\python folder
extract TexConv2.exe, TexConv2.bat, texUtils.dll and gfd.dll to Noesis\scenes folder
i used your findings along with info from previous links i posted.to make this work
extract tex_XenobladeChroniclesX_WiiU_mtxt.py to Noesis\plugins\python folder
extract TexConv2.exe, TexConv2.bat, texUtils.dll and gfd.dll to Noesis\scenes folder
