This time around we'll be looking at how to comp the render passes coming out of Cycles in Natron. This method can be applies in any compositing package but I chose to use Natron for this example. Version 2 released recently and contains a lot of new features, which is why I decided to highlight it. Download it for free here.
As with the previous Natron tutorial, you can download the EXR file used to follow along. If you have any questions don't hesitate to ask!
