Hi all
I tried ridged_mf for terrain on a iso-planet but result is "strange"
If function (x*x+y*y+z*z - (f_ridged_mf(x,y,z, 0.2 , 5 , 7 , 1.6 , 0.1 ,
2)+100)) is used directly in isosurface results ar goog but if same function is
used in pigment

#declare Dec_p=pigment{function{f_ridged_mf(x,y,z, 0.2 , 5 , 7 , 1.6 , 0.1 , 2)
}}

#declare fp_mount=function{pigment{pigment_pattern {Dec_p}}}

isosurface { function { (x*x+y*y+z*z - (fp_mount(x,y,z).gray+100)) }

resulting object is broken
