V-Ray makes full use of regular Maya cameras, but can also add certain attributes to add more advanced functionality to a scene camera beyond the regular Maya camera controls and attributes. These additional camera functions and controls are accessed in Maya in two different ways, depending on the functions desired: as either a number of Extra V-Ray Attributes added directly to the Maya camera node, or as Overrides in Maya's Render Settings window.

Extra V-Ray Attributes allow for per-camera fine-tuning control, while the Render Setting Overrides offers scene-wide control.
