This class implements the OpenXR Render Model Extension. This class implements the OpenXR Render Model Extension, if enabled it will maintain a list of active render models and provides an interface to the render model data. Returns [code]true[/code] if OpenXR's render model extension is supported and enabled. [b]Note:[/b] This only returns a valid value after OpenXR has been initialized. Creates a render model object within OpenXR using a render model id. [b]Note:[/b] This function is exposed for dependent OpenXR extensions that provide render model ids to be used with the render model extension. Destroys a render model object within OpenXR that was previously created with [method render_model_create]. [b]Note:[/b] This function is exposed for dependent OpenXR extensions that provide render model ids to be used with the render model extension. Returns an array of all currently active render models registered with this extension. Returns the number of animatable nodes this render model has. Returns the name of the given animatable node. Returns the current local transform for an animatable node. This is updated every frame. Returns the tracking confidence of the tracking data for the render model. Returns the root transform of a render model. This is the tracked position relative to our [XROrigin3D] node. Returns a list of active subaction paths for this [param render_model]. [b]Note:[/b] If different devices are bound to your actions than available in suggested interaction bindings, this information shows paths related to the interaction bindings being mimicked by that device. Returns the top level path associated with this [param render_model]. If provided this identifies whether the render model is associated with the player's hands or other body part. Returns [code]true[/code] if this animatable node should be visible. Returns an instance of a subscene that contains all [MeshInstance3D] nodes that allow you to visualize the render model. Emitted when a new render model is added. Emitted when a render model is removed. Emitted when the top level path associated with a render model changed.
