It is now time to composite the scene after rendering it.
After the rendering is completed, we will open up a new Blender scene and go to the node editor. Let's delete the default render layer and add an image input node (Add menu | image). Here we will load the exr image sequence that we just rendered. We need to change the mode to image sequence and set the number of frames, exactly as we did for the sea-animated texture. You will see that we now have all the sockets with the render passes that we activated before. Let's dive into the compositing process!
We will start by compositing the image over the sky background:
From the Image output, add the following in sequence: a Glare node (Add menu | Filters), a Mix Color node, and an Alpha Over node (Add menu | colors).
Set Fog Glow with Mix to
1
, Threshold to0.55
and Size to9
and plug it in the second socket of the Mix node. Plug the original Image output into the first socket of the Mix node...
