Camera Settings

OctaneRender^® for Houdini^® uses a standard Houdini camera for rendering. OctaneRender utilizes the Transform parameters from the Houdini camera. The following Houdini camera node parameters are linked to the Octane camera.

Resolution - Configures the OctaneRender final render resolution.
Projection - The Octane camera works in perspective or orthographic modes.
Focal length/ApertureDetermines how much light enters a camera lens. A large aperture produces a narrow depth of field and a small aperture produces a wide depth of field./Ortho Width - Controls the Houdini camera's wide angle and telephoto characteristics. Ortho Width works when you set the Projection parameter to Orthographic.
Near Clipping/Far Clipping - Distance from the camera to the near and far clipping planes, measured in meters.
Screen Window X/Y - These parameters map to the Octane lens shift parameters. This is useful for architectural rendering, if you want to render images of tall buildings or structures from a similar height as the human eye while keeping the vertical lines parallel.
Left/Right/Bottom/Top Crop - Controls camera view cropping for all four directions in the Viewport.
Shutter Time - Determines the shutter duration, specified as a fraction of the frame.
Focus Distance - The depth of the plane in focus, measured in meters.
F-Stop - This is the aperture-to-focal length ratio used to determine how much light enters the camera lens. It controls depth-of-field.

You can find additional camera parameters in the Octane Render Target node (Figure 1). These parameters vary, depending on what type of camera you select (Thin Lens, Panoramic, or Baking). The Thin Lens, Panoramic, and Baking parameters are covered in this article's sub-sections.
