This PR adds support for
KHR_interactivity,KHR_node_hoverabilityandKHR_node_selectabilityas per the specification from Mar 10 2025. The bulk of the implementation work has been done by @pfcDorn and me.Usage
These extensions are not ratified by Khronos yet, so their implementation details might still change substantially. The KHR_interactivity plugin is disabled by default; to enable it follow these steps:
com.unity.visualscriptingUnityGLTFSettingsInteractive scenes can be exported from Visual Scripting script machines. Once the plugin is enabled, script graphs will display hints per node on whether that node can be exported or not. All major visual scripting features should be supported (variables, custom events, subgraphs). If you run into unsupported nodes that you feel should be supported, please open an issue.
Testing
An assortment of ~30 sample files exported with this extension via UnityGLTF can be found here: https://drive.google.com/drive/folders/159YUuZ_DH7_zYBJDU2jh4zcWlxGJX_sg
