For modders of Illusion games like Honey Select, AI Shoujo, and Koikatsu, SB3Utility (or SB3UGS) is an essential, high-powered tool for manipulating Unity assets. Originally developed by Alamar and now maintained by enimaroah, this utility allows you to extract, edit, and replace 3D models, textures, and animations directly within game files.
This tutorial provides a comprehensive guide on setting up SB3Utility and performing common modding tasks. Getting Started with SB3Utility
Before you can start modding, you need to ensure you have the correct version of the tool and any necessary supporting software.
Download: Get the latest stable release (often version 21.0.3 or higher) from the official GitHub repository.
Version Compatibility: While the latest version is generally recommended, some users find that specific older versions (like v21.2) are more stable for certain titles like Koikatsu Sunshine. SB3Utility (often abbreviated as ) is a essential
Unity Editor: For complex tasks, it is often helpful to have the version of Unity the game was built on (e.g., Unity 5.6.2f1 for Koikatsu). Core Modding Workflows
SB3Utility uses a tabbed interface to manage different asset types. Most operations begin by dragging a game archive (like a .pp or .unity3d file) directly into the program window. 1. Editing and Replacing Textures
Textures are the "skin" of your 3D models. Replacing them is one of the most common ways to customize characters or outfits.
Isolate the Material: Open your .xx mesh file, navigate to the Mesh tab, and identify the "Materials Used" for the part you want to change.
Add New Texture: Drag your new texture file (preferably .bmp or .tga) into SB3Utility. Under the Texture tab, select Add Image.
Apply Change: Go to the Object Tree, find your target material, and update the "Texture Used" field to point to your newly added image. 2. Modifying 3D Meshes
To change the actual shape of an item, you will need to export it to a 3D editor and then re-import it. Digital Girl: Modding - Hgames Wiki
SB3Utility (often abbreviated as SB3UGS) is a powerful asset manipulation tool primarily used for modding games developed by Illusion, such as Koikatsu, Honey Select, and AI Shoujo. It is considered essential for modders because it can modify asset bundles directly rather than just extracting them. Core Functionalities
Asset Extraction & Modification: Allows users to extract and edit meshes, animations, textures, audio clips, and scripts from game files like .pp or .unity3d.
Asset Bundle Manipulation: It is one of the few tools capable of modifying Unity asset bundles, which is critical for porting custom models into games.
Editor Interface: The GUI features specific tabs for different asset types, including Meshes, Materials, Textures, and Animations. Basic Tutorial Steps
Preparation: Download the latest version from the SB3Utility GitHub repository.
Opening Files: Run SB3UtilityGUI.exe and drag-and-drop the desired game file (e.g., a .pp or .unity3d file) into the program window. Editing Textures:
Navigate to the specific texture path within the asset bundle. What is SB3 Utility
Export the existing image, edit it in software like Photoshop (maintaining file type and dimensions), and then replace the original file within the utility. Editing Meshes:
Select the mesh from the Mesh tab and export it, often in Metasequoia (.mqo) format for editing.
After editing, drag the new .mqo file back into SB3Utility and use the "Goto Frame" function to align and replace the original mesh.
Saving Changes: Use File > Save or the shortcut Ctrl+S. The tool typically creates a backup automatically. Key Considerations for Beginners
Backups: Always back up your original game files before attempting any modifications to prevent game instability.
Tool Complexity: SB3Utility is more complex than other extraction tools like AssetStudio, but it offers deeper control for advanced modding tasks like rigging and material editing.
Unity Compatibility: For modern Illusion games like Koikatsu, SB3Utility is often used alongside Unity Editor 5.6.2f1 to ensure full compatibility with the game's engine version. Honey Select UI Modding Tutorial
An introductory guide to mastering the core workflows of SB3Utility for 3D model customization. Introduction to SB3Utility
SB3Utility (SB3U) is a versatile, open-source tool primarily used for viewing, extracting, and modifying assets within specialized game engine files, such as those found in Unity-based or Illusion-style applications. It serves as a bridge for modders to swap textures, adjust mesh properties, and manipulate animations without needing a full-scale development environment. Interface and Setup
Upon launching SB3Utility, the interface is divided into three primary sections: the Workspace, the Files tab, and the 3D View. To begin, users must drag and drop the target archive (e.g., .unity3d or .pp files) into the Workspace. This loads the internal file structure, allowing you to navigate between meshes, materials, and textures. Texture and Material Modification One of the most common uses for SB3U is texture swapping. Locate the Texture tab within the loaded file. Select the specific texture you wish to change.
Use the Export function to save the file as a .dds or .png for editing in Photoshop or GIMP.
Once edited, use the Replace button to re-import the file.Ensure the naming conventions and dimensions remain consistent to prevent rendering errors. Mesh Manipulation and Exporting
For more advanced users, SB3U allows for the extraction of 3D geometry. By selecting a Mesh or SkinnedMeshRenderer, users can export the data into the FBX format. This allows the model to be opened in software like Blender or 3ds Max for structural changes. When re-importing, the Drag & Drop method is often used to replace the existing mesh. It is critical to ensure that the bone weights and vertex counts are handled carefully to maintain proper character animation. Saving and Implementation
No changes made within SB3Utility are permanent until the archive is saved. After performing your edits, navigate to the Files menu and select Save. It is highly recommended to keep a backup of the original file, as incorrect offsets or corrupted imports can cause the host application to crash. Conclusion
SB3Utility remains an essential tool for the modding community due to its lightweight nature and powerful manipulation capabilities. While the learning curve can be steep regarding bone structures and material shaders, mastering the basic import/export loop opens up endless possibilities for asset customization.
SB3 Utility is a free, open-source tool that allows users to convert SB3 files to other formats, such as JSON, XML, and even images. It also provides features for editing and manipulating SB3 files, making it a valuable resource for Scratch developers, educators, and researchers.
