Ah, yes, I was aware of using them on exported\exposed values. Will you be adding other parameters to be exported? Like for generators for example?
As far as I can see, making a complete tutorial is probably more time consuming (especially the video variants) than adding smaller examples in the documentation.
I actually prefer reading text and seeing the odd screen shot rather than sitting back and passively watching a video.
I seem to fall asleep a lot while watching video tuts for some reason.
I was thinking that these more theoretical nodes need some practical examples and related descriptions compared to the other more "hands on" types of nodes. I sense great potential in opening up as many parameters as possible to be controlled via math nodes and the likes.
