    Hi, I am making an animation of a worm moving its neck around. The worm body is made with a vector line(shape) and it’s animated in the path layer. I want to attach a face to the end of the moving/swinging neck but I don’t know how to do that except placing it manually frame by frame. I know if the shape of the neck doesn’t change I can simply use “parent/child” to link but it doesn’t work in this case because the shape changes as well as its length.

    Is there any easy way to achieve this? Pleas advise. Thanks a million in advance!

    if it is made with a shape layer ‘line’, you can use the points to nulls command to have nulls follow the vertex’s’s of your line, then parent the face to the relevant null.

    Really?? Can you please explain a bit more? (Sorry, I am still a newbie…). Maybe some reference or tutorial? Thanks a bunch in advance!

    If you have an animated path, selected the path and run the ‘Nulls follow points’ command. If you want to use the nulls to animate the path, select un-animated path and run the ‘Points follows null’ command. Either way, you get a null per point, that you can parent stuff to.

    (command is found in the windows drop down on the top bar)

    It works! The only thing is that when the face doesn’t rotate when it follows the Null. I normally use “Auto-Orient” to paths but it doesn’t seem to work with this. Is there a way to rotate the attached comp as the direction of the point changes?

    you’ll need someone better with expressions than me, but I would imagine yes, there will be a way to ‘link’ the angle of the path to the patented item. You might be better creating a ‘Look at’ null and linking the nulls pos to the item’s rotation, again, you’ll need someone smarter than me! That option gives you more flexibility I think.
