Rendering to elements lets you separate various types of information in the rendered output into individual image files. This can be useful when you work with some image-processing, compositing, and special-effects software.
Render Element Output File Dialog
The Render Element Output File dialog lets you assign a name to a file that saves one element of the rendering. You can also determine the type of file to render, and set up options such as compression, color depth, and quality, depending on the file type.
Individual Render Elements
These topics describe individual render elements, especially those that display a rollout with options.
