Bottle filling using boolean

I am trying to ‘fill’ a bottle with liquid using an animated cube as a boolean mask. However when it is rendered, the cube is rendered as well. See attachment.

How can I make the cube invisible?

In the outliner clicking on the camera icon on the right hand side toggles on/off the objects renderability. You could also just put it on a leyer that you have set not to render.

Funny, I tried the same today. However, for my results I used the Shrinkwrap modifier (faster & sometimes cleaner results).

You can also subdivide the cube a few times, give it a displace modifier with a cloud texture. If you animate this, you can get nice moving surface during filling
