Sb3utility Tutorial ((free)) -
The most common entry point for new modders is texture editing. Using SB3Utility, a user can navigate to a specific material within an archive, such as a character's skin or clothing texture. By right-clicking and selecting "Export," the texture is saved as a standard DDS or PNG file. The modder can then edit this file in Photoshop to change colors, add tattoos, or modify clothing patterns. Once finished, the user drags the file back into the SB3Utility window, selects the original texture entry, and chooses "Replace." The tool then compresses the new image into the specific format the game requires and updates the archive.
Move your newly generated archive file into your game's data directory, replacing the original file (or placing it in a modloader folder if the game supports it). Launch the game to test your modifications.
Open the or Bone sub-panel to view individual vertex weight allocations.
The archive was likely saved with incorrect compression or an unsupported file version. Always keep a backup of your original files before overwriting.
Tracks your actions. If a texture fails to import or a mesh corrupts, the error log will tell you why. sb3utility tutorial

Open Blender, delete the default cube, and import your FBX file. While editing, you must follow these strict rules to prevent the game from crashing:
Use to match the new mesh to the old one if needed, then drag the new mesh onto the old one to replace it. Step 5: Finalize and Save
Clothes and hair must be rigged to the game's original armature (skeleton). Do not delete or rename original bone groups. The most common entry point for new modders
At its core, SB3Utility is a specialized asset editor designed to manipulate the proprietary file formats used by Illusion's Unity-based games. While standard Unity games can often be edited with tools like UABE or AssetStudio, Illusion games utilize unique structures, particularly regarding the Unity3D archives and the .xx model formats. SB3Utility allows users to open these archives without fully "unpacking" them, providing a streamlined environment to view, extract, and replace internal resources.
To verify, look at the to confirm your new design updates correctly. Workflow 2: Modifying and Importing 3D Meshes
Extract the ZIP file contents into a dedicated folder on your drive (e.g., C:\Modding\SB3Utility ).
From your imported FBX tree window, drag the modified mesh line and drop it directly onto the original highlighted destination mesh. Click . The modder can then edit this file in
: Use the Mesh or Object Tree tabs to find the specific item you want to modify.
: Use the built-in search tool to find specific assets by name within large bundle files.
If you’ve ever wanted to go beyond the limitations of the standard Scratch editor—whether to inject high-quality custom sounds, import HD vector assets, or fix corrupted project files—you’ve likely stumbled upon the need for . This powerful, open-source tool acts as a surgical scalpel for .sb3 files (Scratch 3.0 project files).
If the textures look wrong, click the pasted object and use the right pane to adjust the Materials properties, pointing them back to the correct texture maps. 5. Advanced Tutorial: Importing MMD (PMX) Models
: The Object Tree allows you to "Remove" unneeded parts of a file to isolate a specific accessory or mesh, which is vital for creating lean mods.
