## Draco and glTF
|
|
|
|
[Draco™][draco] files contain raw mesh or point cloud data only, but Draco compression can be used on mesh data within [glTF™][gltf] asset files. This allows you to enrich your Draco data in many ways, for example:
|
|
|
|
- Transforms (location, rotation, scale) and object/node hierarchy
|
|
- Multiple meshes/point clouds per file
|
|
- Materials
|
|
- Animation
|
|
- Application specific meta-data
|
|
|
|
The [*Unity glTFast*][glTFast] package provides support for loading, importing and exporting glTF in Unity and utilizes *Draco for Unity* to gain Draco compression support. You have to install recent versions of both packages to unlock that feature. See the package's [documentation][glTFast] to learn how to create and load Draco compressed glTF files.
|
|
|
|
> **Info:** Support for Draco in glTF is available via the [KHR_draco_mesh_compression][DracoGltfExt] glTF extension.
