aenhancers

I am still having the hardest time getting my head around the layer space transforms. Here's what I need to do. I have a corner pin effect on a layer. I need to find the comp position of each animated corner point so I can then apply a corner pin effect to a layer of a different size. All I can find is examples of finding comp position from 3d space and assigning it to 2D effects, not the other way around.

Thanks
