I have a small project where I am trying to add video elements to a painting. My painter friend has made a few shapes on the canvas for me to fill in, some with curves (including the cartoon looking clouds). I thought it would be easy to fill in the curves, but realized I don't operate the mesh warping well enough for this purpose.
Am I missing something obvious? Or, for curved shapes (a few amoebas, for example) would it make more sense to create a mask in photoshop and use it within a single quad?
