I imported an image as a plane in order to place vertices marking all the key contours on it. After a while I realized I didn't know how to make those vertices part of the plane they were on.
If I can't move the vertices on the z axis, and have the image move with them, I can't use the image as a reference the way I'd planned and the whole thing becomes much more difficult.
Is there a way to embed those vertices in the plane that has the image? They are already sitting on it. Or maybe a way to import the image again and integrate the vertices with it then?
