PostProcessing only on Globe

As I understand it now, to apply postprocessing only to specific objects we have to get the Primitives associated with that object. How can I retrieve the Primitive(s) of the Globe to only apply postprocessing to the Globe? Or if it does not work with Primitives, how else can I apply postprocessing to only the Globe?

Thanks

I think this currently is not possible. If this is something that’s important to your project, feel free to open a feature request (https://github.com/AnalyticalGraphicsInc/cesium/issues) and describe your use case (or you can tell me a bit more about it here and I can open the GitHub issue too).
