Rendering passes is the process of rendering different attributes of our scene separately and composing them together to produce the final output that is rendered. Some of the elements available in Lumion are Specular, Lighting, Depth of Field, and some special elements such as Material ID and Skyalpha. We can extract these elements and put everything together in most post-production software that supports the compositing of layers, thereby giving us much greater control over the look of the final result. Let's see how we can access and use these rendering passes.
For this recipe, we can create a small clip using only one snapshot in order to have an image to export. To see how Material ID and Depthmap work, it will be good to add some 3D models to our scene.
