I have been unable to get normals to show up on a DXF object that I
imported into pov (as a smooth triangle mesh? I think) using 3DWin.
Is there some trick to this?

Also, how can I get something to work like (yes, asked question 2-3
times before, not satisfied)

    normal{
        gradient x
        normal_map{
            [0.0    down]
            [0.2    down]
            [0.21    up]
            [1.0    up]
            }
    }

I find the SLOPE map to be pretty much useless, I'm not worried about
slope, I just want it UP in some places and DOWN in others, to my
specification.
