Spotlight can't light the whole area

As you can see on the picture, I don’t need to tell you anything.
Half side is being lighted while the other half is dark as its rendered on “Render Settings”.
I tried in different areas and it’s the same half / half.
If you could help me with it or give me some tips i would appreciate it !

Please help it’s really annoying me, thanks in advance !

Hi,

Is there other lights in our scene ? Try setting the render mode parameter of your light to “important”, that will render your light over the others :slight_smile:
