<description>
Part of the export process. Allows GLTFDocumentExtension classes to provide mappings for properties of nodes in the Godot scene tree, to JSON pointers to glTF properties, as defined by the glTF object model.
Returns a [GLTFObjectModelProperty] instance that defines how the property should be mapped. If your extension can't handle the property, return null, or an instance without any JSON pointers (see [method GLTFObjectModelProperty.has_json_pointers]). You should use [method GLTFObjectModelProperty.set_types] to set the types, and set the JSON pointer(s) using the [member GLTFObjectModelProperty.json_pointers] property.
The parameters provide context for the property, including the NodePath, the Godot node, the GLTF node index, and the target object. The [param target_object] will be equal to [param godot_node] if no sub-object can be found, otherwise it will point to a sub-object. For example, if the path is [code]^"A/B/C/MeshInstance3D:mesh:surface_0/material:emission_intensity"[/code], it will get the node, then the mesh, and then the material, so [param target_object] will be the [Material] resource, and [param target_depth] will be 2 because 2 levels were traversed to get to the target.

<description>
Part of the import process. Allows GLTFDocumentExtension classes to provide mappings for JSON pointers to glTF properties, as defined by the glTF object model, to properties of nodes in the Godot scene tree.
Returns a [GLTFObjectModelProperty] instance that defines how the property should be mapped. If your extension can't handle the property, return null, or an instance without any NodePaths (see [method GLTFObjectModelProperty.has_node_paths]). You should use [method GLTFObjectModelProperty.set_types] to set the types, and [method GLTFObjectModelProperty.append_path_to_property] function is useful for most simple cases.
In many cases, [param partial_paths] will contain the start of a path, allowing the extension to complete the path. For example, for [code]/nodes/3/extensions/MY_ext/prop[/code], Godot will pass you a NodePath that leads to node 3, so the GLTFDocumentExtension class only needs to resolve the last [code]MY_ext/prop[/code] part of the path. In this example, the extension should check [code]split.size() &gt; 4 and split[0] == "nodes" and split[2] == "extensions" and split[3] == "MY_ext"[/code] at the start of the function to check if this JSON pointer applies to it, then it can use [param partial_paths] and handle [code]split[4][/code].

<brief_description>
Describes how to access a property as defined in the glTF object model.
</brief_description>
<description>
GLTFObjectModelProperty defines a mapping between a property in the glTF object model and a NodePath in the Godot scene tree. This can be used to animate properties in a glTF file using the [code]KHR_animation_pointer[/code] extension, or to access them through an engine-agnostic script such as a behavior graph as defined by the [code]KHR_interactivity[/code] extension.
The glTF property is identified by JSON pointer(s) stored in [member json_pointers], while the Godot property it maps to is defined by [member node_paths]. In most cases [member json_pointers] and [member node_paths] will each only have one item, but in some cases a single glTF JSON pointer will map to multiple Godot properties, or a single Godot property will be mapped to multiple glTF JSON pointers, or it might be a many-to-many relationship.
[Expression] objects can be used to define conversions between the data, such as when glTF defines an angle in radians and Godot uses degrees. The [member object_model_type] property defines the type of data stored in the glTF file as defined by the object model, see [enum GLTFObjectModelType] for possible values.

<description>
Appends a [NodePath] to [member node_paths]. This can be used by [GLTFDocumentExtension] classes to define how a glTF object model property maps to a Godot property, or multiple Godot properties. Prefer using [method append_path_to_property] for simple cases. Be sure to also call [method set_types] once (the order does not matter).

High-level wrapper over [method append_node_path] that handles the most common cases. It constructs a new [NodePath] using [param node_path] as a base and appends [param prop_name] to the subpath. Be sure to also call [method set_types] once (the order does not matter).
