This page provides information about the camera overrides tab in V-Ray for Blender.
Overview
The camera overrides control how the scene geometry is projected onto the image, changing how the render looks.

Properties
Camera Overrides – Toggles camera overrides on and off.
Use Clipping – Enables clipping planes.
Camera Type – Types of cameras available in V-Ray. You may set your scene camera to be overridden by selecting one of the following:
Standard – Allows for the current scene camera to be used (usually a pinhole camera).
Spherical – A camera with a spherically shaped lens.
Cylindrical (point) – This camera casts all rays from the center of a cylinder. In the vertical direction, the camera acts as a pinhole camera, and in the horizontal direction, the camera acts as a spherical camera.
Cylindrical (ortho) – This camera casts all rays from the center of a cylinder. In the vertical direction, the camera acts as an orthographic view, and in the horizontal direction, the camera acts as a spherical camera.
Box – Six standard cameras placed on the sides of a box. This type of camera is excellent for generation of environment maps for cube mapping and generates a vertical cross format image.
Fish Eye – This special type of camera captures the scene as if it is a pinhole camera pointed at a 100% reflective sphere that reflects the scene back into the camera's shutter, as with using a light probe in HDRI photography. You can use the Dist and FOV settings to control which part of the sphere is captured by the camera. Note that the virtual reflective sphere has always a radius of 1.0.
Warped Spherical (old-style) – A spherical camera with slightly different mapping formula than the Spherical camera.
Orthogonal – An orthographic camera enabling flat, non-perspective views.
Pinhole – Overrides the scene camera to force it to be a pinhole camera.
Spherical Panorama – Spherical camera with independent horizontal and vertical FOV selection that is useful for generating lat-long images for spherical VR use.
Cube6x1 – A variant of the Box camera with the cube sides arranged in a single row. Unlike the Box camera's output, Cube6x1 does not produce an empty space in the output image and is quite useful in generating cubic VR output.
Height – Specifies the height of a Cylindrical (ortho) camera. This setting is available only when the Camera type is set to Cylindrical (ortho).
Auto-fit – Controls the auto-fit option of the Fish Eye camera. When enabled, V-Ray calculates the Distance value automatically so that the rendered image fits horizontally with the image's dimensions.
Curve – Controls the degree of warping for a Fish Eye camera. A value of 1.0 corresponds to a real world fish-eye camera. Lower values increase warping, while higher values reduce warping. Technically, this value controls the angle at which rays are reflected by the virtual sphere of the camera.
