.avatar — VRoid Avatar File
VRoid Project (Pixiv) · 2019
.avatar files are 3D character models primarily used for anime-style avatars in VRoid Studio and compatible applications.
Key Features
- Contains complete 3D character data (mesh, textures, rigging).
- Optimized for anime-style characters.
- Supports blend shapes for facial expressions and body customization.
- Designed for interoperability with VRM-compatible software and platforms.
Best For
- Creating ready-to-use anime-style 3D avatars.
- Quickly generating expressive and customizable characters.
- Importing characters into VTubing software and VR platforms.
- Sharing 3D character assets within the VRoid ecosystem.
Less Ideal For
- General-purpose 3D modeling or complex scene creation.
- High-fidelity photorealistic character rendering.
- Storing animation sequences (use separate animation formats).
- Web-based 3D model viewing without conversion (prefer glTF).
Common Use Cases
- Creating custom avatars for virtual reality social platforms (e.g., VRChat).
- Developing characters for VTubing and live streaming.
- Designing characters for indie games or interactive experiences.
- Personalizing digital representations in metaverse applications.
How to Open It
- Open directly in VRoid Studio to edit the character model.
- Import into VRM-compatible applications like VSeeFace, VRChat, or Unity.
- Use 3D modeling software that supports VRM import (e.g., Blender with a VRM add-on).
What is a .avatar file?
An .avatar file, often associated with the VRoid Studio software, is a 3D model file specifically designed for creating and customizing anime-style characters. It contains all the necessary information for a character's mesh, textures, rigging, and blend shapes, allowing for easy import and animation. These files enable users to build unique avatars for use in various virtual environments, games, and VTubing applications without needing extensive 3D modeling expertise. They are a key component for creators looking to express themselves in digital spaces with personalized 3D characters.

Frequently Asked Questions
VRoid Studio is a free 3D character creation software developed by Pixiv, specifically designed to make creating anime-style 3D models easy.
Yes, you can import .avatar files into VRChat after converting them to the VRM format, which is directly supported.
.avatar files are the native project files for VRoid Studio, while .vrm is a standardized format derived from them, making them widely compatible.
Technical Details
The .avatar format is essentially a wrapper for the VRM (VRoid Model) specification, which is itself based on the glTF 2.0 standard. It packages the 3D model data, including vertices, UV coordinates, materials, textures, skeletal information, and blend shapes, into a single, portable file. This standardized structure ensures compatibility across various VRM-supporting platforms.
