The Camera Settings window can be accessed through the Exposure settings button on the V-Ray for Revit Ribbon. Unreal works with standard Unreal cameras and Viewports. However, you you will not have exposure control of your camera. To use exposure control and other real-world camera settings you have to use the VRayPhysicalCamera Blueprint Actor.

UI Path: ||Ribbon|| > V-Ray tab > Camera panel

 

Note

In order to have full visual parity between viewport and render you have to disable some of the Unreal posprocess and lighting components. You can do so from in viewport Show > Post Processing and leave only Depth of Field, Postprocess Material and Vignetting. From Show > Lighting Component uncheck Ambient Occlusion.

Camera Mode – Specifies the type of camera to use for rendering. The cameras in V-Ray generally define the rays that are cast into the scene, which essentially is how the scene is projected onto the screen. V-Ray supports several camera types:

Standard Camera – A traditional pinhole camera.
Stereoscopic Camera – Creates two virtual cameras based on the current camera, one for each in a pair of stereoscopic images.
VR Camera (Cubic 6:1) – Six standard cameras are placed on the sides of a box for generating cubic VR output.
VR Stereo Camera (Cube 12:1) – Twelve standard cameras are arranged to generate stereoscopic VR output. Half of the cameras generate the left cubic output, and the other half generates the right cubic output.

 

Exposure Settings

Exposure (EV) – Controls the render brightness in exposure value (EV) units. EV ranges correspond to the following lighting environments:

Since the VRayPhysicalCamera is based on the Unreal Camera all features are accessible but only some are supported in the current version. The VRayPhysicalCamera Blueprint Actor is accessible through the Modes panel by searching for VRayPhysicalCamera or from VRayForUnreal > Content > BP > Actors > VRayPhysicalCamera in the Content Browser Tree. Select the Blueprint and drag and drop it in the level.

White Balance (K) – Specifies the color temperature in degrees Kelvin that appear white in the render. The following temperature ranges correspond to the following lighting environments.

Effects

This rollout is only accessible when the Camera Mode is set to Standard Camera.

Defocus – Controls the strength of the defocus (bokeh) effect. Objects farther away from the Focus Distance will appear blurry.

Focus Distance – Specifies the distance from the camera that objects will be in sharp focus. Note that Focus Distance is synchronized with Revit's project units. 

Optical Vignetting – Controls the strength of the vignetting effect which gradually darkens the edges of the render.

 

UI Text Box

Defocus and Focus Distance are in a relation. The Defocus (bokeh) effect will be applied correctly after the user has set up the Focus Distance. 
To define the Focus Distance, open any floor plan view in Revit and measure the distance from the Current View camera to the object/s that you want to appear in sharp focus.
