is it possiple to link single points of a mask or a shape to specific positions, for example to a motiontracking attachpoint.
To make it clear an example:
you have got a video with blue sky and a plane flying through it. now you have motiontracked the plane and may want to draw a line from the upper left corner of the video (0,0) to the tracked plane.
The problem is that there is no field for typing in expressions for single points of a shape, you can only use the whole path, but if you write this expression into the shape path:
thisComp.layer("tracked plane").motionTracker("Tracker 1")("Track-Punkt 1").attachPoint
you get an error message.
any solution for that?
