The render queue lists the current batch of scenes to be rendered.

When loading a scene normally from inside the Indigo GUI, only a single item is added to the render queue, however multiple scenes can be added, with a halting condition (on rendering time, samples per pixel or both) to specify how long they should render for.

A Render Queue can be saved by clicking File -> Save Queue. A Indigo Queue file is automatically created when exporting animations from Indigo's 3D modelling package plugins. More information about saving and using Render Queues.
