I have been tring to track mask vertices according to tracking point created by Track Motion. I learned this tutorial "How to attach a mask point to a layer in After Effects? | Fxfx.net ::: Digital Art Tips & Tricks". It's easy to track a vertice by this. But the RotAE place the vertice direct at Attach Point of Tracking Point. My problem is how to shift the vertice a few pixels next to Attach Point of Tracking Point at all frames together. I think about parents of Tracking Point or something like this.
I don't want to use any stipendiary plug-in. I use After Effects CC latest version.
