@Christoph-Hart I think I am missing something but this won't work for me.
The "whatever" here is just the name of the scriptFx correct (whatever we named the xml file)?
** Edit: Something strange with how the project was set up. There is something buggy about this feature that I can't quite put my finger on. Does the scriptnode have to be compiled to dll first? I solved the issue but I can't say exactly how. This has happened to me numerous times in the past.
