Thanks, Nose Man! I went through the whole thing twice, following all your steps exactly, but I can't get the Rangemap to do its job to reverse the data. My spheres look just like yours before the Rangemap (kinda lumpy and squished in the wrong places), but when I add it and adjust the Max Output to negative, it's like the Smoothing is just turned off. Any ideas? I'm on R20- not sure if it only works in R21, but I don't know why that would be. Has anyone else tried it in R20?
I've attached my project file if that's helpful.
Thanks!
