Override FOV - with this setting you can override the Softimage's FOV angle. This is because some V-Ray camera types can take FOV ranges from 0 to 360 degrees, whereas the cameras in Softimage are limited to 180 degrees. Auto-fit - this setting controls the auto-fit option of the Fish-eye camera. When Auto-fit is enabled V-Ray will calculate the Distance value automatically so that the rendered image fits horizontally with the image's dimensions. FOV - here you specify the FOV angle (only when Override FOV is turned on and the current camera type supports FOV angle). Distance - this setting applies only to the Fish-eye camera. The Fish-eye camera is simulated as a Standard camera pointed to an absolutely reflective sphere (with a radius of 1.0) that reflects the scene into the camera's shutter. The Distance value controls how far the camera is from the sphere's center (which is how much of the sphere will be captured by the camera). Note: this setting has no effect when the Auto-fit option is enabled. Height - here you can specify the height of the Cylindrical (ortho) camera. This setting is available only when the Type is set to Cylindrical (ortho). Curve - this setting applies only to the Fish-eye camera. This setting contorts the way the rendered image is warped. A value of 1.0 corresponds to a real world Fish-eye camera. As the value approaches 0.0 the warping is increased. As the value approaches 2.0 the warping is reduced. Note: in fact this value controls the angle at which rays are reflected by the virtual sphere of the camera. Depth of Field
These parameters control the depth of field effect when rendering with a standard Softimage camera. The parameters are ignored if you render from a VRayPhysicalCamera. On - enables or disables the calculations of the Depth of field effect. Aperture - this is the size of the virtual camera aperture, in world units. Small aperture sizes reduce the DOF effect. Sides - this option allows you to simulate the polygonal shape of the aperture of real-world cameras. When this option is off, the shape is assumed to be perfectly circular. The number on the right controls how many sides the polygonal shape of the aperture has. Center bias - this determines the uniformity of the DOF effect. A value of 0.0 means that light passes uniformly through the aperture. Positive values mean that light is concentrated towards the rim of the aperture, while negative values concentrate light at the center. Rotation - specifies the orientation of the aperture shape. Focal distance - determines the distance from the camera at which objects will be in perfect focus. Objects closer or farther than that distance will be blurred. Anisotropy - this option allows the stretching of the bokeh effect horizontally or vertically. Positive values stretch the effect in the vertical direction. Negative values stretch it in the horizontal direction. Get from camera - when this option is on, the Focal distance is determined from the camera target. Subdivisions - controls the quality of the DOF effect. Lower values are computed faster, but produce more noise in the image. Higher values smooth out the noise, but take more time to render. Note that the quality of sampling also depends on the settings of the DMC Sampler as well as on the chosen Image sampler. |
