This page introduces V-Ray camera topics and generally how to access them. Please click on the appropriate topic(s) below for the full documentation and proper usage information.



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.


Adding Extra V-Ray Attributes for Cameras

Adding extra V-Ray attributes is the most direct way to add specific functionality to a Maya camera. Choosing one of these options adds a rollout to the camera's shape node called Extra VRay Attributes. There you can change the camera's attributes directly.

These options include tools to control the camera like a real camera with F-stop, shutter speed, ISO film speed, and other settings; turning the camera into a dome camera; and setting up a stereoscopic camera for rendering left/right pairs of images.

For details on these options, see Camera Attributes.


Creating Camera Overrides in the Maya Render Settings Window

In Maya's Render Settings window's Overrides tab, in the Camera rollout, parameters can set scene-wide overrides to the Maya camera, to primarily define the type of camera with which to render the scene, such as a standard pinhole camera or a panoramic VR camera for instance.

Many parameters can be overridden including camera type and settings for Field of View (FOV), Depth of Field (DoF), and Motion Blur functions for the scene.

For details on these options, see Camera Overrides.


Additional V-Ray Camera Tools

V-Ray automatically installs several external tools in the bin folder of your V-Ray for Maya installation. These tools are launched outside of the Maya application and can be found in the Chaos Group folder in the Start menu in Windows.

In OSX these additional tools are found in the ChaosGroup folder in the Applications folder.

In Linux you can find these tools in /usr/ChaosGroup/V-Ray/Maya nnnn -x64/bin (where nnnn is the Maya version).




Lens Analysis Tool

The primary V-Ray tool for creating, previewing and editing V-Ray lens files (.vrlens). This suite of tools includes a camera distortion analyzer and a tool for correcting/distorting images. It provides for a very realistic level of camera distortion simulation. Find out more: Lens analysis tool


Lens Effects Filter Generator

A simple tool for composing filters (HDR images in .hdr format) specially designed to produce filters for the Lens Effects in the VFB. Find out more: Lens Effects Filter Generator
