Important Notes
Since the third-party web browser plugin currently in use is outdated, it has been replaced with a maintained one. However, the following limitations apply:
Windows 32-bit systems are not supported.
On macOS, it still runs via Rosetta, so the initial loading time will be long (expected to be resolved in a future update).

Note
About Engine
This update, coming after a seven-year interval, upgrades the engine from Unity 2019 to Unity 6.0. The purpose is to adapt to the latest SDKs, enhance compatibility with modern computer hardware, and prepare for full native support for Apple Silicon
Due to the significant leap between engine versions, there is a possibility of instability or unknown issues occurring
About Cubism SDK
This SDK update may cause issues with some older models; if you encounter any, please feel free to provide feedback
About Cubism masking options
This update is intended solely to provide experienced creators with more detailed options. Modifying Cubism masks under certain settings can severely impact performance; please do not make adjustments unless necessary or if you are unsure of the usage
Instead of increasing the mask size, it is recommended to first try increasing the number of mask textures. Total mask resolution = number of mask textures × mask size. In some cases, six 1024-sized textures can achieve the same visual quality as one 4096-sized texture. In such scenarios, the former is preferred because the total resolution is lower, resulting in a smaller impact on performance

Version：2025.9.25
Json Config: Added "add_submodel" and "remove_submodel" commands
Json Config: Renamed "change_cos" command to "change_model"
EX Studio: Merged Live2D/Spine editor and uploader
EX Studio: User interface optimization
Common: Added submodel feature
Common: Added model slot editing feature
Common: Bug fixes
About Model Slot Editing
Mainly used to configure the default position, size, etc. of models when they are loaded into a specific slot. When a model is loaded for the first time, it will use this slot setting.
In the Control Panel or Quick Menu, click Edit Model Slot to open the editing panel, where you can configure the default position, size, and other settings of a model slot. You can switch model slots using the menu in the upper-left corner. Drag the crosshair intersection or adjust the X/Y values in the panel to set the default position. The Reset All Model Transforms button resets all models’ position, size, and related settings for the current model slot.
Use case:
If a user wants all models to be placed in the corner of the screen without editing each one individually, they can move the model slot to the corner and click the 'Reset all model transforms' button. After that, all models loaded for the first time will default to this position.
About Merging Live2D and Spine Editors
After the merge, you can freely switch between Live2D and Spine models, including switching via the change_model command. Submodels of different types can also be displayed simultaneously.
About Submodels
Use cases
Some models separate the background and character. You can set the character as the parent model and load the background on startup, allowing both models to move and scale as a single unit.
When creating models, you can separate UI, character, and background to reduce complexity of a single model. This also enables dynamic switching of backgrounds or characters, offering greater flexibility than simply replacing textures.
Limitations
Submodels can only be added or removed by the parent model through commands. Submodels cannot have their own submodels. When the parent model is removed, its submodels are removed as well.
When adding a submodel, you can set its display order from -3 to 3. The parent model is at position 0, positive values display in front, negative values display behind. Multiple models can occupy the same position, but overlapping may cause display issues.
Users cannot adjust the position or size of submodels; only initial position and size can be set in the Json configuration. Submodels will follow the parent model’s movement and scaling.
Since there is no dedicated editing panel for submodels, you cannot change expressions or adjust mesh opacity from the editor; these can only be changed via commands.
Submodels use the parent model’s text box for text display, so if multiple models display text at the same time, they may compete for the same text box.
When using Workshop items or WPK files, submodels share the parent model’s save data, meaning changes to floating-point variables, affinity, etc., affect both. With LPK or Json files, the submodel’s save data is separate from the parent model.
Submodels and parent models can be different types (e.g., parent is Live2D, submodel is Spine).
To ensure performance and prevent abuse, a maximum of 6 submodels can be added.
How to use
Add submodel: add_submodel config.json 1 (1 is the position, an integer in the range -3 to 3. The parent model is at position 0; values greater than 0 display in front, values less than 0 display behind.)
Remove submodel: remove_submodel config.json (removes all submodels with the configuration name config.json)

About the breaking change to model position and size
Reason for the change:
To simplify the setup of model position and size, and to prepare for an upcoming major feature update.
Before the change:
Both the model slot adjustments and individual model adjustments were applied. When loading another model, it would inherit the current model slot settings plus its own saved settings.
After the change:
Model slot adjustments have been removed. Each model’s position, size, and related settings are now saved completely independently. The editing panel will only edit each model individually. Models are saved separately based on the model slot number and the screen aspect ratio.
Impact on existing users:
On the first launch after the update: The settings of loaded models will be overwritten by the model slot settings, which may cause changes to model position or size.
On the second and subsequent launches: Models will be displayed only according to their individually saved settings.
For old scene snapshots: If a model was individually adjusted, its position or size may change. If it was not individually adjusted, there will be no effect.
