VGO

VGO is a new type of 3D data format.

Features

You can save basic information of 3D model such as Node, Transform, Rigidbody, Collider, Mesh, Blend Shape, Material, Texture.
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.

Experiments

Supports WebP format in addition to normal PNG, JPEG for image type (media type / MIME type) in textures.

        private VgoModelAsset? _VgoModelAsset;

        private void Start()
        {
            _VgoModelAsset = _VgoImporter.Load(_FilePath);
