It can tell if something is moving, to generate motion blur. It can differentiate individual objects from each other. It knows what light comes from diffuse shaders, specular shaders, ambient occlusion, reflection, and refraction. It even knows if you’ve been bad or good.
This was a quick chapter for me – because of my side projects and experimentations I’d already come across most of the things that are covered in this chapter. It is a great sum-up of the most important stuff though, so if you’re coming to this with no prior experience you will have a lot of knowledge to acquire.
The chapter starts with a lot of tips on optimizing render times for test renders. These are very useful for increasing productivity and are worth a marker on the book for reference. Then it goes on to explain the compositor and related subjects like render layers, to add the final extra kick to your images. It shows the nodes we’ll probably be using the most for getting common effects (like depth of field, motion blur, glare…), and then leaves it up to us to explore the rest.
Here is our scene with that extra kick:
I started to write about other resources for learning compositing in Blender, but it turns out I have a lot to say, so it deserves its own post :) coming tomorrow!
