Well, the first time I saw this was about 2/3 years ago. Someone was trying to make foot prints in the snow. I started to use it for skin on skin in P4. I'm not sure what happened to the original, might have turned into a script to keep the foot print after the foot moved to next point. Nice to see old ideas come alive again. I did this in about 1 min. I didn't adjust the mag zone so it's not perfect. You can add all the groups you want to the 1 mag and make the finger slide all the way down to the toes, if you wanted to.
