I have a fairly complicated material node tree that I'm building. All of a sudden some of my node inputs seem to be locked. If I click on an unconnected node input and change a number it immediately resets back. Dragging it as a slider does the same thing. Is there a way of locking nodes that I may have triggered with a keyboard shortcut?
I've tried digging into the API in the outliner but I can't figure out what's going on with these nodes. Only some of them seem to be affected, including both node groups and built-in nodes. Of course I've tried the last couple builds of Blender but they're still locked. I've rebooted too. I really don't want to have to rebuild this thing.
