After extraction of the .pak files in the ABT APK as well as the OBB and its pak files from the XPK2 script, on update v1.36.8, I got a lot of .xgt files and they appear to be in game texture files. I was hoping someone could help me open and view the textures. The heading is XGST. Any advice on doing this or how its done? If so thanks . Some end with _pvr, _atc, _dxt and _etc.

A sample is here: https://drive.google.com/open?id=1Fw0ZH ... AJ4d4CZtc7

seems a simple header, this one was just rgba8888 but need more samples of each variety,
but i have a feeling PVRTexTool will be better for the mobile compressed types.

Thanks for that!

Here are more samples https://drive.google.com/drive/folders/ ... sp=sharing. These include files in the OBB. Getting the SDK, it apparently works with the RAW data wrapping but I always have to type the right size... any way to find out the size without about 50 guesses? I figured out in the wrap raw data function in PVRTexTool, if the offset becomes 32, it is often correct and correctly renders the xgt as an image.

here are my findings about the 32 bytes before image data so you don't have to guess

Code:

4bytes - magic (XGST)
2bytes - data offset
2bytes - header size
1byte - num mips
1byte - flag1
1byte - flag2
1byte - flag3
4bytes - format
2bytes - width
2bytes - height
2bytes - width2
2bytes - height2
4bytes - zero
4bytes - data size

i should be able to make a Noesis python script to open the dxt samples but others must use PVRTexTool.

Are the others meaning plain .xgt? Meanwhile, the colors are for some are messed up after typing the right size.

i mean any samples that don't have pvr, etc or atc in the filename,
but now i'm starting to think you don't need all format types because
they might all just be the same image any way and dxt would be all you need.

How about these files? I always get the size correct but the image doesn't look correct... http://www.filedropper.com/megaporktextures

i already gave you the specs from the dxt sample, you can use TextureFinder on them.
512x512 dxt5

It looked like that on my end, before I asked for help, I didn't expect it to look like that but like a plain texture, any way to make it look like it would properly appear in-game, also is that from the PVR SDK or another project?

i don't know what you mean by plain texture and i know nothing about this game
maybe the game uses shaders to enhance the look? ,and TextureFinder is just a
program and has nothing to do with the PVR SDK.

Did you compile a Noesis script for these files as of now?

Acewell, posted Fri Dec 14, 2018 8:23 am (41380)

here is Noesis python script to open the xgt and xgt_dxt textures only.
*script updated April 15, 2020*

supports rgba4444, rgba8888, rgb565, r8a8(?), dxt1, dxt5 and ETC

Thanks so much! The script works fine except on XGTs using a different RGBA type as the colors are off on them... Any advice on making a custom XGT? Like would I have to use PVRTexTool to create a compressed texture and copy its bytes to an XGT for each type?

you have to upload the problem samples so i can fix script,
i don't play this game and don't know what the colors should look like.

Oh ok. Here's some that won't open in Noesis and one that doesn't render with correct RGBA values... http://www.filedropper.com/abgo

okay i swapped the channels in the rgba8888 format and added rgb565,
the samples that won't open are ETC1 and you should use PVRTexTool.

Ok thanks. I created a custom RGBA8888 XGT, via using PVRTexTool and copying the data bytes to overlap the original data, all I need is to fix its MIPs and other flags, I used a new image, with the settings the game would know, loaded the image I want to the surface and saved it, then copied the raw image to the original XGT's raw image data.

I tried PVRTexTool but I cannot open ATC compressed files...

i updated the Noesis python script to support ETC, you may need to update Noesis too.
the compressonator should be able to open atc, post some samples.

Yeah... DXT on Noesis gives me something red for every DXT texture. Maybe that can help.

Also fails to open XGTs in localisation. https://drive.google.com/folderview?id= ... QEfWZ5Fu0v

updated the Noesis python script for the r8a8(?) localisation xgt
samples, i guess is right, i don't really do fonts that often.
i added support for the ETC samples previously, you probably didn't update Noesis.

ETC works fine (but have to manually edit to include XGT_ETC in the extension list which also works), DXT doesn't and gives a red shape for every file.
