So I am trying to create a Day Night cycle on a sphere but it doesn't work the way I want it to. As the model is hex tiled, you see the edges of the hex tiles also lit up like below. I am using a directional light source for the same.
I don't want the above effect. I want it to ignore the edges and just be a straight line instead. Something like below
Is there a way inside Unity that I could achieve this effect just using the lights?
