i found my mistake

i was staying away from the parent ID so much i missed #7
7. Select "!!-VisibleUnderwater" node and paste the number into
"Parent ID". it is now linked to the "<empty" node.
so i put it in the regular ID box on step 7 instead of the "parent ID" box
i got it working finally
i am now a graduate of Peabody's S3D tutorial
thank you for your time and patience
