An important paradigm in 3delight for Maya is the Render Pass. Simply put, a Render Pass is a rendering context that encapsulates a list of rendering options and a list (or set) of objects to be rendered. All 3Delight for Maya does is encapsulated all the these options (i.e. all the Rendering AttributesThe Render Settings presented in the Render Settings window) inside a Render Pass node. It is then possible to create many such nodes and select and edit the one we want to use for rendering. A single Maya scene can contain any number of such passes. Each one is rendered independently with possibly very different outputs.

The selected active one is used for renderings launched using Render Current Frame or Batch Render options of Render in Maya’s Render menu. By It is also the one used when rendering using Maya's Render command line (see Batch Rendering). By default there is only one Render Pass and it is named 'renderPass'.
