1. Install Unity and Set Up UniVRM

Before processing the VRM model, install Unity and add the UniVRM package to your project.

1. Download and install Unity.
   • It is recommended to use Unity 2022.3 LTS or later versions for better compatibility.
2. Download UniVRM from GitHub Releases.
   • Each UniVRM version corresponds to specific Unity versions, so ensure compatibility before downloading.
3. Import UniVRM into your Unity project:
   • Go to Assets > Import Package > Custom Package and select the UniVRM package.
   • Follow the on-screen instructions to complete the installation.

2. Import the VRM Model and Configure Expressions

Once UniVRM is set up, import your VRM model and add new expressions.

2.1 Load the VRM Model

1. Navigate to VRM > Import in the Unity toolbar.
2. Select and open the VRM model file.
3. The model will be imported and appear in the Hierarchy panel.
4. Ensure the VRM Meta component is correctly set up.

2.2 Add New Expressions

If the model was converted from another format to VRM, expressions may not be pre-configured. In this case, you will need to manually adjust each BlendShape to properly define the character's facial expressions.

To enhance character expressiveness, add new expressions with corresponding BlendShapes.

This process applies to DSS (DSS) versions v0.8.2 and later.
