To apply it, select one or several perspective cameras, and run either
- Get->Property->Arnold Properties->Camera Options
- Arnold->Properties->Camera Options
- SITOA_AddCameraOptionsProperties (script editor).
Starting with 3.1, this property defines the type of the Arnold camera. If not applied, the standard settings of the Softimage camera are used to define the Arnold perspective camera.
However, if you want to define a different kind of camera (cylindrical, fisheye, spherical), you have to use this property.
This is also mandatory if you want to access Arnold-specific controls, like those defining depth of field, aperture size, and type, advanced motion blur, and remapping.
Lens shaders, previously used to set camera-specific attributes, have been discontinued.
For a complete description of the options, see the camera page.
