Try with an "iso_hf" made this way (slow but versatile)
So did I do the island rocks on this image

#declare PigMap = pigment {
image_map {tga "your_image.tga" once interpolate 2}scale 2 rotate x*90
translate <-1,0,-1>// convert the source image of your hf to pigment
}
#declare Fun1 = function {pigment {PigMap}} //convert pigment to function
#declare Accidents= function {pigment {wrinkles scale <0.4,0.1,0.4>rotate
x*20 }} //disturbing function, here I use a pigment to be able to transform
it
#declare fn_X = function{(Fun1(x,y,z).gray*0.3)-Accidents(x,y,z).gray*0.1
}
isosurface {
function {y-fn_X(x,y,z)*1}
contained_by { box { <-3,-0.20,-3>, <3,1,3> } }
accuracy 0.1
max_gradient 8
}
