• fov - The horizontal field of view in radians.
• orthographic - Enable to have orthographic projection instead of perspective (RenderView::fov doesn’t matter in this case, in favor of RenderView::orthographicWidth).
• transform - A transformation (rotation + translation) which defines where the camera is and how it is rotated. The matrix is in column-major format and you will need to calculate it yourself. You can't set rotation angles as in most 3D software. The default camera orientation with identity matrix is so that +Y is pointing up and -Z is the view direction. If your scene uses +Y for up-axis, you will need to set V-Ray's scene up-axis accordingly - see the Units subsection in the settings section below.

If you want to enable motion blur, set the SettingsMotionBlur plugin on parameter to 1. It also has the geom_samples parameter that affect quality, but may cost a lot of render time if increased. It should equal the number of geometry samples in the geometry data if it is non-static. Note that this plugin (SettingsMotionBlur) conflicts with CameraPhysical.

The SettingsLightLinker plugin allows you to define include or exclude lists for lights and objects, so that for example specific lights do not affect some objects etc. Refer to the plugin parameter metadata for explanations.

If you are not using CameraPhysical for depth of field, you can use SettingsCameraDof instead. Note that this plugin (SettingsCameraDof) conflicts with CameraPhysical.

• on - Set to true to enable DoF.
• aperture - The size of the camera aperture in scene units. Note that increasing this number corresponds to decreasing the physical camera's F-number.
• focal_dist - Distance from the camera to the focus plane in scene units.

The .vrscene can store multiple cameras, where only one can be set as ‘renderable’ at a time. The rest of the cameras can be chosen for rendering, for example in V-Ray Standalone, by using the -camera command flag. This is useful, as oftentimes a project requires rendering different sequences from different cameras, while nothing else changes in the scene - a simple example would be to render two different views of the same visualization and in this way, the same scene can be rendered twice with V-Ray Standalone. An example scene with two cameras would have one them to render by default while the other will have dont_affect_settings flag raised.
