The screenshot is of the default sphere which I squashed a bit to make the ugly shading easier to see. It is still quite hard to see the problem in the screenshot, though it is much worse in game. You can see if you look carefully at the screenshot that there are darker lines extruding along the lines between vertices from the unlit parts of the sphere to the lit parts.
It is using the ‘Default-Diffuse’ material. The same happens no matter what shader I use. And no matter what mesh I use. I have the graphics quality set to ‘fantastic’ and am running it on a very powerful computer.
Does anybody else have this issue. How do I resolve it?
Thank you very much.
