Overview
The Camera Settings window can be accessed through the Exposure settings button on the V-Ray for Revit Ribbon.
UI Path: ||Ribbon|| > V-Ray tab > Camera panel
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.
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:
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.
