Is it possible to change the way faces are shaded to give the appearance of a digital display? I would like to take a plane that is 8 faces wide by 4 faces high and select certain faces and apply a surface shader to them leaving the unselected faces with the original surface color. I thought I could do this with a blend shape but that didn't work. I would like to have a slider or switch that would control 3 or 4 different "digital" shapes.
