Okay, so I'm trying to create a triangle, and I have 3 null objects, each one has been motion tracked to different areas on my footage. What I want to do is create a triangle, and pick-whip each vertex to the corresponding null object's position. Is there a way to do this, and if so, how?
Many thanks in advance
I am trying to create an effect like on this video

You could use corner pin, pickwhip one corner to an adjacent corner, and use expressions like this on the others:

fromComp(thisComp.layer("Null 1").transform.position)

Thankyou Dan, your advice worked like a treat :)
I had to create a shape layer which filled the composition, added the corner pin effect and pick-whipped the lower left corner to the upper left one to turn it into a triangle then from there on I can pick-whip the other corners to my position trackers :p
Thankyou very much for the advice
