That’s why the rendering process can be very time-consuming even with the most powerful hardware and software available in the market. During the rendering procedure, the computer reads large amounts of 3D data and makes a lot of calculations to be able to create 2D images or frames. The compositing stage can save huge amounts of time and money in a 3D animation studio. Why use compositing in 3D animation production? The reason why they are used most often is that they cover a wide range of material combinations in different surfaces. The most common types of compositing are: Several compositing programs can be used to touch up and edit digital renders or add special effects by compositors in an animation studio. But most compositing today, including 3D animation, is done through digital tools. Pre-digital compositing techniques go back as far as the 19 th century. In 3D animation, compositing is about combining two or more render passes or adding layers to create a single image or series of images with predefined properties. Compositing can include special effects, stage extension, environment creation, blue/green screen replacement, etc. Generally speaking, compositing is the combining of visual elements from separate sources into one image, in a way it creates the illusion that all those elements are parts of the same scene. The definition of compositing originates from photography meaning combining two or more images to make a single one. Your browser does not support the video tag. The following video is an example of compositing for a short 3D animation visually explaining how it’s done in a nutshell: Here, we’ll take a look at an overview of compositing and how it fits within the realm of the 3D animation pipeline. Some 2D visual effects can also be added if necessary. This is where the final look of animation really comes together. The process can be as simple as putting two layers together, or as complex as matching hundreds of layers and adjusting their properties such as depth of field and color. It involves taking the render passes from the production stage and combining them together or mixing in additional images or adjustments layers, to create a more cohesive composition. The first step of 3D animation post-production in 3D animation studios is called compositing. Post-production artists have a number of tools that can make up the look of a project in whatever way they want without having to render the whole project again. At this stage, the final touches are added to the project to make it look polished and professional. Up to here, we have covered the pre-production and production phases of the 3D animation pipeline.
