Drag and drop the new component over the old one and select .
Go to the right-hand Mesh tab, choose (or another compatible format like .obj / .fbx if applicable) under the Export format option, and click Export.
: Run SB3UtilityGUI.exe and drag-and-drop the desired game file (e.g., a .pp or .unity3d file) into the program window. Editing Textures :
: This often happens if you try to replace a mesh with one that has a different number of bones or unaligned weights. Missing Textures
For power users, SB3Utility includes a built-in script editor that exposes the raw project.json . This allows you to batch-edit code. sb3utility tutorial
Import updated .fbx files from Blender directly back into the game file structure while maintaining bone weights. 2. Setting Up Your Environment
If the original mesh used mat_hair , your edited mesh must use mat_hair .

: Located on the upper left, this displays your opened archives ( .unity3d , .pp , .assets ) and expands hierarchically to show inner assets like Animators, Textures, and MonoBehaviours. Drag and drop the new component over the old one and select
# Create a new sprite sprite = sb3utility.Target(project, 'Hello World') project.targets.append(sprite)
SB3Utility exposes this structure directly. When you change a costume here, you are literally replacing the file inside the ZIP.
: Keep the exact same resolution (pixel width and height) and file extension to prevent rendering errors. Paint your modifications and save the file. Step 3: Injecting the New Texture
. Unlike basic extractors, SB3Utility allows you to modify internal game file assets, manage bones, edit SkinnedMeshRenderers, and manipulate textures safely without corrupting the parent .unity3d or .pp files. Mastering this tool is an essential milestone for anyone looking to transition from a casual mod user to a game asset modder. Prerequisites and Installation Editing Textures : : This often happens if
Invalid JSON will corrupt your project. Always make a backup before manual editing.
Contextual tabs ( Mesh , Texture , Material , Morph ) that dynamically update based on your selection.
Open the exported file in your 3D modeling software (e.g., Blender, Metasequoia). Make your changes to the model. Note: Do not change the rigging (bones) unless you know what you are doing. Step 4: Import the Modified Mesh
