I have this pinching effect that I want to move across a background image. Can't do it with the mesh grid. I searched googled and came across something about pre-comp helping.
After a few hours, I cannot figure it out. Can someone post a detailed example or explanation that the total braindead can understand?
Move the layer to be pinched inside the pre-comp or apply an effect like Transform or Motion Tile before the Mesh Warp and animate the parameters.
