• 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.

In shading setups, textures can be projected from cameras. This can either be the same camera used for rendering, or another camera in the scene, used only for projecting a texture. In both cases, an extra SettingsCamera and RenderView plugin is exported for the camera projection with the dont_affect_settings flag raised. This is similar to the Multiple Cameras setup. In all cases, it’s a good idea to export one camera for rendering, and another one for the texture projection, even if it’s the same camera, as different properties apply for each.
