Nathan,
I have been trying to do the method you posted, however I am having trouble getting the hand to animate. I can get it to move along one path, but bringing in multiple paths at once does not seem to be possible. When I copy them into the position field it copies them as a group of masks and not a motion path. How did you manage to copy multiple paths in together? Did you need to add each one individually?
Thanks in advance for your for your help.
