Why does my render result look different than the rendered preview in the 3D view This is the rendered preview.


This is the render result.


I tried to increase the sample size but the problem persists. I want the render to look like the rendered preview.
You seem to have an active compositing step. To disable all compositing, uncheck the Compositing checkbox under Post Processing in the Properties Area.



Compositing alters the image after it is rendered, it is set up in node editor. You could also delete all compositing nodes, alternatively to turning compositing off.
