I know it's a very new thing (post 2.4 era anyways) but there seems to be very little documentation and examples for PyNodes in general, and the little there is doesn't seem to work in latest SVN (currently r57165).
My idea is to make a Cycles material node that has a vector output socket for each of the object(s) UV Maps, so that I don't need to look up what the name of the UV Map is in the Object Data Properties and copy-paste that into the Attribute node each time. This seems like a reasonably easy node to code, failing that even just a node like the Attribute one that can fetch an objects Custom Property to be used in the material.
Either way, I'd like some help in setting up a simple PyNode like that. Is it possible? Can someone provide example code of simple working PyNodes?
