This page provides information on V-Ray Camera settings.

Overview
The Camera Settings window can be accessed through the Exposure settings button on the V-Ray for Revit Ribbon.
V-Ray for Revit offers the Lens Effects Filter Generator tool which allows the creation of various specially designed filters for the Lens Effects render effect.

Camera Settings
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.
VR Spherical Panorama – Spherical camera with independent horizontal and vertical FOV selection that is useful for generating latlong images for spherical VR use.
VR Cubemap – 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 useful in generating cubic VR output.
Stereo – Enables or disables the Stereoscopic rendering mode. Stereoscopic images will be rendered "side-by-side" or "one on top of the other" based on the Output Layout option. You do not need to re-adjust the image resolution as it will adapt automatically.
Exposure Settings
Exposure (EV) – Controls the render brightness in exposure value (EV) units. EV ranges correspond to the following lighting environments:
| EV Range | Environment |
|---|---|
| 25.0 to 14.0 | Bright Sunshine |
| 14.0 to 12.0 | Sunshine |
| 12.0 to 10.0 | Overcast Sky |
| 10.0 to 5.0 | Bright Interior |
| 5.0 to 0.0 | Floodlit Building |
| 0.0 to -3.0 | Dim Ambient Light |
| -3.0 to -6.0 | Night - Full Moon |
| -6.0 to -15.0 | Night - Starlight |
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.
| Temperature Range | Environment |
|---|---|
| 2000 | Candle Flame |
| 2000 to 3250 | Incandescent Lighting |
| 3250 to 4250 | Halogen Lighting |
| 4250 to 5050 | Fluorescent Lighting |
| 5050 to 6550 | Average Daylight |
| 6550 to 10000 | Daylight |
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.
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.
