Cameras - Panoramic
After installing this plugin, a camera type named "Cy Pano Cam" will be available in the "Cycles" category. This camera is used to set up panoramic renders that are not possible with the normal Max cameras.
Type - The type of panoramic projection to use.
Equirectangular Lattitude - Sets the vertical field of view for the panoramic camera. Negative values are below the horizon and positive values are above it. Only applies if the type is Equirectangular.
Equirectangular Longitude - Sets the horizontal field of view for the panoramic camera. Negative values are left of the camera and positive values are right. Only applies if the type is Equirectangular.
Fisheye FOV - Sets the FOV to use. Only applies if the type is Fisheye Equidistant or Fisheye Equisolid.
Equisolid Fisheye Focal Length - Sets camea focal length. Only applies if the type is Fisheye Equisolid.
Equisolid Fisheye Sensor Size - Sets camea sensor size. Only applies if the type is Fisheye Equisolid.
Near Clip - Distance from the camera to the near clipping plane.
Far Clip - Distance from the camera to the far clipping plane.
Stereoscopy options will only apply when you also select a stereoscopy mode other than "None" in the advanced render options.
Spherical Stereo - When enabled, the render will be performed in such a way that the output can be used in VR and similar setups. If you are doing a stereoscopic panorama render, you almost certainly want this to be enabled.
Use Pole Merge - When enabled, the stereo effect will be reduced at the poles of the panoramic render (straight up and straight down). Visual artifacts may appear at the poles if this is not enabled.
Merge From - Angle where pole merging will begin. The stereo effect will be gradually reduced beyond this angle.
Merge To - Angle where pole merging will end. The stereo effect will cease entirely beyond this angle.
Note: For the above angle measurements 0 degrees means level with the camera and 90 degrees means straight up or down relative to the camera.
