The aim of this tutorial is to render a scene by parts for example an animation. In many cases, your project grows slowly and you can't start the rendering until your entirely finish the project. As a result, the rendering starts very late and close to the deadline which makes for example rendering big animations impossible to do. But... big projects can often be divided by parts. I mean separate objects that won't change until the deadline like the environment, non-project objects, and projects you are sure it will be kept till deadline. Therefore, with render layers, you can render the steady parts first, quietly, and just the last part of your project before the deadline. This saves you a lot of time from when you need it.

Separate parts

You should separate parts within layers. For example:

  • Layers 1-2 : Steady parts (environment)
  • Layers 3-4-5 : Project (still not finished)
  • Layer 6 : lights and cameras

Render layers

Let's create render layers. These are presets of which layers to render.

  • Renderlayer "Environment" : tick layers 1-2-6
  • Renderlayer "Project" : tick layers 4-5-6

We also may create a full render layer to render the full project scene once a time.

  • Renderlayer "Whole scene" : tick all layers
