• You can also save the information of Human Avatar, Spring Bone, Animation, Cloth, Light, Particle System, Skybox for use in Unity.
• You can also save the information of Blend Shape Preset for use in the application.
• The file format uses IFF chunk as the base.
• Use JSON, BSON, Binary as internal data.
• The geometry coordinate system can have both right-handed and left-handed data.
• It is a specification that allows its own definition extension (chunk, schema).
• It is designed to support partial encryption.
• Resources are basically included in a file, but they can be cut out in another file.
• Resources can compress data with sparse, and have their own definition of the more powerful sparse.
• There is no direct compatibility with glTF.
• It is possible to convert to other formats including glTF by expanding the data in Unity Editor.
