Having complete control over your renders has never been so easy. Just follow this in-depth, step-by-step process.<\/span><\/h2>\n\n\n\n

On many occasions, you’ve probably heard of layer composition as a way to operate in post-production in order to make your renders even better.<\/p>\n\n\n\n

Imagine a situation where you want to tweak some reflections, but the render has already been made and it’s practically impossible to isolate your reflections, unless you start your render from stratch.<\/p>\n\n\n\n

Consequently, the only way to make changes without affecting the other parts of the scene is to consider layers<\/strong>. <\/p>\n\n\n\n

Layers and Render Passes<\/span><\/h3>\n\n\n\n

When you approach rendering, you have to find a way to isolate different elements in separated layers<\/strong>. That doesn’t necessarily mean the background from the foreground, but mainly the type of light rays affecting your scene.<\/p>\n\n\n\n

For instance, a renderer knows what diffuse rays<\/strong>, as well as reflective rays<\/strong> are, but, if we don’t manage render passes, the render engine would include everything in the same layer.<\/p>\n\n\n\n

Therefore, a render pass<\/strong> is an image containing specific aspects of the scene. The same render pass is being imported as a layer <\/strong>in After Effects.<\/p>\n\n\n\n

Here, we have an example of a rendered scene, which I created for this article. I decided to manage reflections, subsurface scattering effects, and refraction for the glasses.<\/p>\n\n\n\n

Building the final render with all the layers included, known as a Beauty pass<\/strong>, is our primary goal.<\/p>\n\n\n\n

Compositors have to take all the passes and create the final image, as we see below:<\/p>\n\n\n\n

Most Common Render Passes<\/span><\/h3>\n\n\n\n

There are many ways to compose your final image by isolating specific light rays<\/a> and elements. Almost all of the software allows for rendering specific layers. For this purpose, I’ll be using Maya<\/strong> with Arnold<\/strong>, but choose the renderer of your liking. <\/p>\n\n\n\n

Here’s the list of the most common render passes that we’ll take into account<\/strong>:<\/p>\n\n\n\n
