Multi Layer Rendering - Anyone know why one of my layers is not rendering?

Hi, I am following this tutorial

and am noticing that at the end when it is time to render the 4 separate passes - which are referred to as beauty, shadow, mist, AO - I am getting 3 rendered files, but nothing is created for the beauty pass.

I can’t see anything obviously wrong.ompositing looks, and I don’t see anything obviously wrong.

I have foreground and background layer. Everything just like in the tutorial (as far as I can tell).

Just can’t figure out what might be preventing the beauty pass from producing a rendered file.

Ideas?

thanks
