I don't know if this is a bug or just me not getting something, most likely the later. 

  I loaded up a simple scene into octane (a ball, cube, and a plane).  I was playing around with the livedb textures and moving the node link from one to the next one.  The node links change from a triangle to a circle when you do.  So I added three textures to the scene and connected all three connections on the mesh node.  The cube was rendering strangely so I thought that it was being smoothed so I went to change the setting and it wasn't there.   Here is a screen shot and you can see that in the inspector there is no access to the default settings:
Are the settings removed when you connect and then disconnect a node link?  It would be nice if there were some defaults or the original settings were remembered when you disconnect a link.  Or am I missing something?  Is there a way to get back the settings so I can change the smoothing?
Ok I just looked at the outliner and was able to get to the setting there, so I guess it would be nice to be able to do the same in the inspector.  I did crash octane one time when I was moving the node links around.  But I'm unable to reproduce it.  All I remember is that the link disconnected from the output link and I think I just released the mouse button, then octane crashed and popped.
