I don't mean to be rude, but how could anyone possibly answer your
question given so little information? SMOOTH works fine on 3d data. I
can easily observe a difference in the data:

You could do something similar with your data to convince yourself that
SMOOTH is working. Then you would know that your problem lies elsewhere
and you could start looking for other possibilities.
