Although the original report was about the docs, the real issue was in the API. My original commit started from a copy-paste from the Switch Node. However I don't use custom1 for thew Switch View node. The docs is slightly incomplete since it would be nice to mention the views here. Or maybe even expose them via Python. But honestly they are generated depending on the scene multi-view settings.
