Why can't I do something like:

 normal{
        function {noise3d(x,y,z)}
               normal_map {
                          [0.00  up]
                          [0.20  up]
                          [ 0.21 down]
                          [ 1.0   down]
                          }
                }

Is there anything I can do to make this happen? All the docs talk about
much more complicated scenarios than this simple one, which ought to be
the most useful!

It needs to be:

 normal{
        function {noise3d(x,y,z)}
               normal_map {
                          [0.00  1]
                          [0.20  1]
                          [ 0.21 0]
                          [ 1.0   0]
                          }
                }


Plus it needs to be in a texture {} statement (or at least should be).

No, this doesn't work!

Maybe you can look at "slope_map" ???
