For example, there are benefits to rendering a single image/shot into multiple ‘render passes’ where different elements of the scene are separated out onto different layers and rendered independently with an alpha channel (i.e. transparency information). These passes need to be overlaid and blended together in ‘post’ (i.e. in a compositing package like After Effects). With this extra step you gain additional control over processes that would otherwise take longer to render ‘in camera’ (i.e. in your 3D package). We will composite together one of the sequences from your movie in order to add fake depth-of-field effects (i.e. blurring), a process that can be tricky and processor-intensive at render time in Maya.
