Octane Camera: Unversal Camera
The Universal camera in OctaneRender® is a full-featured camera, with many features that mimic real world photographic lenses, and support for five different camera types:
Thin Lens- The default Octane camera type.
Orthographic- Removes any perspective from the image.
Fisheye- Ultra-wide angle/spherical result, driven by the parameters discussed here
Equirectangular- Special purpose format, driven by the Panoramic attributes discussed here
Cubemap- will re-project the environment into a series of image rectangles within the frame composition, as determined by the Cubemap layout in the Panoramic section

Input Parameters
Lens Shift - The lens shift on X, as a factor of the image width and on Y, as a factor of the image height. The third value is ignored.
Pixel Aspect - The X:Y aspect ratio of the rendered pixels
Fisheye Angle (Camera must be set to Fisheye) - The Fisheye camera's field of view, measured in degrees.
Horizontal FOV (Camera must be set to Equirectangular) - The horizontal field of view, in degrees. This sets the X-coordinate for the camera's horizontal field of view in the scene. This is ignored when cube mapping is used.
Vertical FOV (Camera must be set to Equirectangular) - The vertical field of view, in degrees. This sets the Y-coordinate for the camera's vertical field of view in the scene. This is ignored when cube mapping is used.
Distortion Texture (Camera must be set to Thinlens) - Enables the distortion texture.
Spherical Distortion (Camera must be set to Thinlens) - The amount of spherical distortion.
Barrel-Distortion Corners (Camera must be set to Thinlens) - Straight lines appear curved, affecting corners.
Spherical Aberration (Camera must be set to Thinlens) Rays hitting the edge of the lens focus closer to the lens.
Coma (Camera must be set to Thinlens) - Rays hitting the lens edge have a larger field of view.
Astigmatism (Camera must be set to Thinlens) Sagittal and tangential rays focus on different distances from the lens.
Field Curvature (Camera must be set to Thinlens) - The curvature of the plane in focus.
Near Clip - Distance from the camera to the nearest clipping plane, measured in meters.
Far Clip - Distance from the camera to the farthest clipping plane, measured in meters.
Focal Depth - The depth of the plane in focus, measured in meters. If you are having trouble seeing a result when you adjust this setting, double-check to make sure that Auto-Focus is enabled. Auto-Focus overrides the Focal Depth setting.
- The follow inputs relate to Distrotion/Aberration:
Aperture - The radius of the camera's lens opening, measured in centimeters. Low values have a wide depth-of-field, where everything is in focus. High values have a shallow depth-of-field, where objects in the foreground and background will be out of focus.
Aperture Aspect Ratio - This allows users to squash and stretch the depth-of-field disc.
Aperture Edge - Modifies the relative distribution of rays across the aperture, impacting the hardness of the edges of bokeh shapes. A value of 0 will result in no discernible depth of field. Higher values increase the contrast towards the edge. Values between 0 and 1 simulate an apodization filter.
Aperture Blades - The number of blades forming the iris diaphragm.
Aperture Rotation - The rotation of the aperture shape in degrees.
Aperture Round - The roundness of the blades forming the iris diaphragm.
Central Obstruction - Simulates the obstruction from the secondary mirror of a catadioptric system. This option is only enabled on circular apertures.
Notch Position - Determines the position of the notch on the blades, active when the Notched Aperture Shape is chosen.
Notch Size - Scale of the notch, active when the Notched Aperture Shape is chosen.
Custom Aperture
- The following inputs relate to Optical Vignetting:
Vignette Distance - The distance between the lens and the opening of the lens barrel.
Vignette Scale - The scale of the opening of the lens barrel relative to the aperture.
- The following inputs relate to the Split-Focus Diopter:
Diopter Focal Depth - Depth of the plane in focus measured in meters.
Diopter Rotation - Rotation of the split-focus diopter in degrees.
Diopter Translation X - X-Direction translation of the camera plane for the split-focus diopter.
Diopter Translation Y - Y-Direction translation of the camera plane for the split-focus diopter.
Diopter Boundary Width - Width of the boundary between the two fields.
Diopter Boundary Falloff - Controls how quickly the Split-Focus diopter focal depth blends into the main focal depth.
Output Parameters
The OCTANE Universal Camera node output can only be pluigged into the Camera input of the Octane RenderTarget Node.
Universal Camera Options


Lenses in the real world are never perfectly manufactured, and often suffer various artifacts, one of which is distortion, anmother of which is aberration. Many image processing applications can remove distortion from an image. In some cases, it may be necessary to introduce lens distortion in order to match the appearance of live action photography.
Requires the Camera mode be set to "Thinlens."
- Distortion
Use Distortion Texture - Enables the distortion texture.
Distortion Texture - The Distortion texture input.
Spherical Distortion - The amount of spherical distortion.
Barrel - Straight lines appear curved.
Barrel (Corners) - Straight lines appear curved, affecting corners.
As with Distortion, Aberration also occurs in real world lenses. Aberration produces a variety of visual artifacts which the Universal camera can reproduce.
- Aberration
Spherical - Rays hitting the edge of the lens focus closer to the lens.
Coma - Rays hitting the lens edge have a larger field of view.
Astigmatism - Sagittal and tangential rays focus on different distances from the lens.
Field Curvature - The curvature of the plane in focus.

Autofocus (Toggle) - Keeps the focus on the closest visible surface at the center of the image, regardless of the aperture, the aperture edge, and focal depth values. This setting is on by default.
Focal Depth - The depth of the plane in focus, measured in meters. If you are having trouble seeing a result when you adjust this setting, double-check to make sure that Auto-Focus is enabled. Auto-Focus overrides the Focal Depth setting.
Aperture - The radius of the camera's lens opening, measured in centimeters. Low values have a wide depth-of-field, where everything is in focus. High values have a shallow depth-of-field, where objects in the foreground and background will be out of focus.
Aperture Aspect Ratio - This allows users to squash and stretch the depth-of-field disc.
Aperture Shape (Drop Down)- Controls the shape of the aperture. Choose from Circular/Polygonal, Notched or Customer Aperture (Sets the custom aperture opacity map. The projection type must be set to OSL Delayed UV.),
Aperture Edge - Modifies the relative distribution of rays across the aperture, impacting the hardness of the edges of bokeh shapes. A value of 0 will result in no discernible depth of field. Higher values increase the contrast towards the edge. Values between 0 and 1 simulate an apodization filter.
Aperture Blade Count - The number of blades forming the iris diaphragm.
perture Rotation - The rotation of the aperture shape in degrees.
Aperture Roundedness - The roundness of the blades forming the iris diaphragm.
Central Obstruction - Simulates the obstruction from the secondary mirror of a catadioptric system. This option is only enabled on circular apertures.
Notch Position - Determines the position of the notch on the blades, active when the Notched Aperture Shape is chosen.
Notch Scale - Scale of the notch, active when the Notched Aperture Shape is chosen.
Custom Aperture - Sets the colour of the opacity for the opacity map plugged into the Custom Aperture node input.

The split focus feature allows focusing the camera into two separate regions. This effect mimics lens diopter filters that would be attached to the front of a given lens to achieve the effect in real world optics. The attributes are defined below:
Enable (Toggle) - Enables the split-focus diopter.
Diopter Focal Depth - Depth of the plane in focus measured in meters.
Rotation - Rotation of the split-focus diopter in degrees.
Translation - Translation of the split-focus diopter.
Boundary Width - Width of the boundary between the two fields.
Boundary Falloff - Controls how quickly the Split-Focus diopter focal depth blends into the main focal depth.
Show Guide (Toggle) - Displays guidelines toggling this option on or off will restart the render.
