# glTF Schemas<no value>
When you install the [SDK](../../introduction/sdk-contents/) it will add a folder that contains a number of **{{< glossterm >}}gltf{{< /glossterm >}} schema** files. These files are JSON formatted and can be used with tools other than 3Ds Max or Blender to create your own import/export tools and other plugins. You can find more information about the glTF schema format from the following link:

-   <https://github.com/KhronosGroup/glTF>

 

If you are using 3Ds Max, then installing the SDK should also have installed a plugin for the version of 3Ds Max that you are using, and this permits you to use the schemas listed here without having to do anything further. You can find more information on the plugin contents, here:

-   [The 3DS Max Plugin](3ds-max-plugin/the-3ds-max-plugin/)

 

For information on how to use the Blender plugin that uses these material schemas, please see here:

-   [The Blender Plugin](blender-plugin/the-blender-plugin/)
