How to make VRM file

Tweet

A VRM file can be made by UniVRM, which is a standard implementation of VRM in Unity. Before we dive into the details, let’s take a look at 4 core steps for making a VRM file:

1. Import a 3D model and UniVRM into a Unity project. Set up/adjust the model’s materials, etc.
2. Export the 3D model as VRM in Unity (Model Normalization)
3. Import the VRM file into the Unity project and customize the settings such as license, spring bone, expression, eyelook, first-person
   • To make sure customized settings (e.g. facial expression) are working, check your model in play mode
4. Export the 3D model as VRM again. Setup completed.
