can't find the 3d model for the dragon quest walk

[kato akira]

I searched for assets files in the Dragon Quest Walk apk.
I used UABE to look for 3D models and looked through about 50 files, but I can't find where they are.
Is it an asset that can't be extracted with UABE?

For this game most models aren't in the apk, they're downloaded to the cache folder as you play. So you either need to see it in-game to have the files, or try finding another way to download resources from the source. They also started stripping the Unity version from the files a while ago (at least, last time I checked), which means some programs might not load all the models if the version isn't specified.

Thank you.
I started the game and downloaded the data and was able to find the model file.
But when I try to view the .assetbundle file using UABE or assetstudio, I can't see the data.
Are these files encoded?

I think it's just that the Unity version is stripped to 0.0.0 which will cause some programs to fail to read it. I tested today with the latest Android assets dumped from my device. It seems to load most files in AssetStudio if you type 2020.3.39f1 in Options > Specify Unity version before loading. Some models still might not load, such as the samurai armor mns_0514_01 screenshot attached, in which case you can try UABEA, AssetRipper, Unity, or some combination of tools.

To look at the samurai armor model I loaded it in UABEA and exported with the extension .asset (not sure if that's necessary, but I seem to remember files without extension not working in Unity) then dragged and dropped the files into Unity editor's Assets folder. You can try to export the model from Unity with plugins, or use AssetBundleBrowser to build and export the package, which should then be able to load in AssetStudio.

Also textures look like they're swizzled and probably won't work with Perfare's AssetStudio, but you can use newer forks or UABEA. Maybe some newer versions out there will load the stripped files without the extra work, I'm not sure.

Thanks for the detailed explanation
I also want to look at the Dragon Quest tact model
but I have the same problem and can't open it in assetstudio
How do I find out the correct version of an assetbundle like these?

[Boxy]

No problem. Most of Dragon Quest Tact's models are encrypted, but there's a working solution in the UnityPy discord. There's also a tool there to automate decryption.

Thanks so much !
I'll look into UnityPy
