[GLTFDocument] extension class.

</brief_description>

|
Extends the functionality of the [GLTFDocument] class by allowing you to run arbitrary code at various stages of GLTF import or export.
|
||
|
|
[b]Note:[/b] Like GLTFDocument itself, all GLTFDocumentExtension classes must be stateless in order to function properly. If you need to store data, use the [code]set_additional_data[/code] and [code]get_additional_data[/code] methods in [GLTFState] or [GLTFNode].
