Every time I create a project and do a render I see that there's always one side of the object that is "dead". I marked it red in pictures. I understand that the light can't fall on every side equally and one'll always be darker but it shouldn't look THAT unrealistic. And it doesn't mater what material I use or how much I rotate my object to get better lightning, there is always a side that looks "dead" and flat. It's quit visible and hard to hide.
Where do I fail?
Right now I use standard version.
