TGA map abnormal file

[douchi]

TGA地图是加密的，就像一个游戏引擎自定义格式。有人能解密它并将其转换成正常的图像格式吗？

Hi!

Did I understand correctly that the APK file of the game is called com.pwrd.xxajh.huawei and weighs about 2GB?
If so, this TGA is stored in .pak files inside "assets" folder, right?

Hello, yes, so the files are stored in media2.PAk, media3.pak

For me it looks like this is the in-game texture format, just named ERA, but with TGA extension. At least, game library have some functions like "Texture::_parser_era" (in one row with "Texture::_parser_pvr" and "Texture::_parser_dds").

I'll try to write a decoder, but do not promise something.

Thank you for your help and look forward to your good news.

Hi friend, what's the latest

Hi!

After some research, I detected, that this is ASTC texture compression with custom header.
I'll polish the script and post it some hours later.
Main reason is that there are can be cubemap textures, so I want to support it.

Example of "c_257_cj_he.tga"

Hi, you're fantastic. Look forward to it!

here is a quick Noesis python script to open your samples until aspadm releases his complete solution.

supports astc 6x6, top level mip only

Thank you. It's amazing.

[aspadm]

Sorry for make you waiting so long. This is the corrected version of Noesis python script, that supports texture with several layers (e.g. cubemaps) and with differrent block sizes.

Thank you and acewell for helping me. Solved my big problem!

Hi, there, Acewell. Could you take a look at this for me? This is an Android exported PNG map, but it doesn't display properly. It's probably encrypted. SAMPLE FILE: https://mega.nz/file/72iwtcrl#g9orr1k68 ... as5yetqhyu
