I am trying to setup the Superfly skin shader described in another thread here but when I try to add the nodes I can't find the Redfilter or Bump2Normal nodes anywhere in any of the menus or sub-menus. Do I need an add-on to get these or am I doing it wrong?

Also, I can't find a Color Map or Bump Map node but I can find an image_map node. Is this the same thing?
