Adding a normal is easy to add and gives you a lot of options to work
with. Any pattern that works as a pigment also works within a normal
statement. I tested this example with the .png you sent me and it
effectively removed the problem you were seeing (although I did go
a bit overboard with it - YMMV).
See below for a simple example -
height_field
{
png "devils_tower_WY.png"
smooth
translate <-.5, 0, -.5>
scale <15,1,15>
pigment { White }
normal { granite 1 scale .5 }
}
