How to preview & export game assets

This is a 2-in-1 guide for exporting Unity games, both methods achieve the same end-goal but serve different use cases.

• AssetStudio - Download (AssetStudioModGUI-Net9_win64.zip)
• AssetRipper - Download (AssetRipper_win_x64.zip)

Scroll down to the Assets section and download the version suited for your machine, for Windows download the ones above. Inside the zips is the programs, extract them anywhere then find AssetStudioModGUI.exe and AssetRipper.GUI.Free.exe respectively.

AssetStudio

Running AssetStudioModGUI.exe opens a CMD window tied to the application. In the top left is dropdown menus, we'll use File, Export, Filter Type and later Options. (Tips: Debug -> Show console logger to hide the console. In the top right Color Theme -> Dark Mode to turn on dark mode.)

Click "File -> Open Folder then select ATLYSS_Data and click Select Folder in the bottom right. The directory is probably C:\Program Files (x86)\Steam\steamapps\common\ATLYSS which you can paste into folder path at the top to get there.


When it is done processing the assets there'll be objects in Scene Hierarchy. Don't worry about that and click on Asset List instead to see the big list of game assets!

Admittedly it's a bit overwhelming. Although you are able to preview Texture 2D and Mesh objects here.

Using the Filter Type menu you can specify what asset types to display, for example selecting Texture2D and Mesh only displays those assets. Double click and stretch the Container bar to change the sorting and see the full folder paths. These container strings represent folder trees in Unity Editor that developers use to keep their assets organised.

Generally the textures/meshes are in _graphic and audio is in _sound, currently advised to use AssetRipper to extract AudioClips as they'll be converted to WAV instead of OGG. Check out Vanilla Textures and Clip Documentation!

You can click on any of the Texture2D and Mesh objects to preview them in the right. At the bottom is controls for RGBA control and moving the 3D models!

Before we begin exporting we need to check Options -> Export Options to change Group exported assets by to Container Path.

Now you can either right click on files you want to export (holding control or shift to select multiple files works) or use the Export dropdown options. After you do choose a output folder and click select folder, it'll automatically open when complete.

AssetRipper

Running AssetRipper.GUI.Free.exe opens a CMD window tied to the browser tab.
In the top left is some dropdown menus but we'll only be using File and Export for this guide.

Click "File -> Open Folder then select ATLYSS_Data and click Select Folder in the bottom right. The directory is probably C:\Program Files (x86)\Steam\steamapps\common\ATLYSS which you can paste into folder path at the top to get there. You can also use Open File to rip individual AssetBundles from mods like custom maps if you get to that point.

The console will begin processing the assets and refresh the tab when complete, turning the button in the centre green. Click Export -> Export All Files then select a output folder path and use Export Primary Content.

The export may take a little while, inside the folder will be Assets, Assemblies and Scripts. From here you're on your own or until a guide tells you to get something from here.
