Vignette (ellipse mask) not rendering?

Hello there!

I wanted to try the new ellipse mask, so I made a little low poly image to then follow this tutorial

It works well inside the compositor, but when I hit render again, the effect does not appear…

Here’s what it looks like in the image below…

Do you guys know what I am doing wrong?

Thank you in advance! :yes:

You have to plug the multiply node into the Composite node.

The composite node is what renders. The viewer node only shows you whatever is plugged into it.

Thank you it works!
