GLTFDocumentExtension

GLTFDocument extension class.

Description

Extends the functionality of the GLTFDocument class by allowing you to run arbitrary code at various stages of GLTF import or export.

To use, make a new class extending GLTFDocumentExtension, override any methods you need, make an instance of your class, and register it using GLTFDocument.register_gltf_document_extension.

Note: Like GLTFDocument itself, all GLTFDocumentExtension classes must be stateless in order to function properly. If you need to store data, use the set_additional_data and get_additional_data methods in GLTFState or GLTFNode.

Method Descriptions

void _convert_scene_node ( GLTFState state, GLTFNode gltf_node, Node scene_node ) virtual

Part of the export process. This method is run after _export_preflight and before _export_preserialize.

Runs when converting the data from a Godot scene node. This method can be used to process the Godot scene node data into a format that can be used by _export_node.

Error _export_node ( GLTFState state, GLTFNode gltf_node, Dictionary json, Node node ) virtual

Part of the export process. This method is run after _export_preserialize and before
