My lighting does not render how it appears in the lray preview?
I am really struggling with rendering a scene.
I have just a livingroom scene. When i use the lray preview in window, it looks great, nice and light etc.
When i click render - it comes out really dark and I am unsure why.
Why is there such a big difference between the two?

The preview is controlled by the Draw Settings pane, the render by Render Settings - compare them to look for possible reasons (e.g. Tone Mapping).
