Hi Nicolas, Right, a phenome watcher on one mesh to drive phenomes on another is that it? So its a kind of inverse of the picture I gave you. Perhaps, if you set up each phenome in the ice tree and then compare the distance to its self on the mesh as it moves. The average of the array puts out a scalar value, so when this hits zero you will have a match. if you add a rescale node you can make go from 0 to 1. You would have to have the original shape positions stored first to compare. It's a thought anyway.
