# How to render while in the compositor?

In a tutorial at 3:22 the guy rendered while in node editor, but didn't say how.

I have tried other tutorials but they all don't say how to do this.

• Could you link to the tutorial and time in question?

• To see a rendered image in the background of the compositor window, the backdrop option needs to be checked. The image displayed is whatever is plugged to a viewer node. If what you want to display is part of the rendered layers, the image needs to be rendered first by pressing f12. Check this tutorial: cgcookie.com/blender/2011/01/11/…
