Writing on Water
I am trying to work out the best way to create the impression of writing on water.
The scene is a video of an actor facing the camera writing with their finger on a vertical plane of water. The ripples spread out and deform the entire frame.
The intention is to use a plane with a water material and use a bump map to deform the plane.
Creating the bump map is the concern ….. how.
Is there a way to make something like a small sphere move along a path (matched to the actors finger movement) and deform the plane.?
Is this possible?
There must be a way easier than manual keyframing.
This wont spread the ripples so something extra is needed …but what?
Your guidance is sort.
Thanks
