I see it now. Thanks again. I'm still not clear how to alter the turbulence
parameter once it is declared in a scene, For example, how would I pop it
directly here:
#declare Sphere = function {f_marble_turb{x,y,z}}


but I understand how to change the entire declaration in the functions.inc
file so I can always just declare the whole f_marble_turb directly in the
scene and change the warp value there.

Thanks again,
D.
