hex2obj - good utility. But for each file their individual hex values. : \

thanks

Hello, Mrtest.

I'd like to participate in an analysis, too.
I'd like to advance work comfortably, so could you tell me the location of the model data or extracting method?

Some anon on The iDOLM@STER General board on 4chan extracted Fumika's mesh (though it appears to be mirrored) and made it available here:

According to anon, he is getting the meshes out using a modified version of disunity 0.4 and he has done some of the others as well, but they all require manual fixing.

yeah, they could be fetched using a MakeH2O project.
Sadly the unity3D files are too different, so only one (and a "half") of 3 checked models were extracted correctly:

So any news on models or animations?
It seems that Maku-chan has ported bones and(animations) or morphs somehow

[MarieRose1301]

I spoke to Maku-chan about the textures and here
The texture format is PVRTC2 and PVRTC4 (PowerVR Texture Compression 2bpp/4bpp)
All of the textures are inside the unity3d.lz4 files
This is the link explaining the format, it's in Japanese though: http://www.webtech.co.jp/blog/optpix_labs/format/4930/
And this is the original email I got from him:

こんにちは。
キャラクターの胴体モデルに使用されているテクスチャデータは3d_tx_bodyから始まるunity3d.lz4ファイルに格納されています。
3Dモデルに使用されているテクスチャのピクセルフォーマットはPowerVR Texture Compression 2bpp/4bppのPVRTC2とPVRTC4で各アルファチャンネル有りと無しが使われいます。

簡単な解説

縦横サイズやフォーマットはヘッダ情報で判別することができます。

How do you extract the models now that the old way is impossible?

[oamio]

Now it's encrypted. Do you know what to do?

[chrrox]

You need to play on a real device and do url monitoring to grab the files.
I have not found any android emulators that have the 3d model mode enabled i think they blacklisted all emulators from loading 3d models in the app.

[oamio]

I think this file is a new encryption file.

I know that it's still available in the Nox app player.

I can get it to play in any emulator it only does the 2d mode tho and blocks the 3d mode.
the url database is an sqlite3 database with a password on it.
If I got the 3d mode working in an emulator I could just dump it from ram.

I suggest to install the GLtools.

This app makes it possible to behave like using fake GPU and select 3d mode on emulator.
Launch, install, grant superuser access, choose CGSS, and config as below.
Enable custom settings for this app
Use fake GPU info
