You can animate the transformations of a camera, including any of its rig elements such as the camera interest. If you are animating the camera rig, there are some special considerations for rotation. However, you can disconnect the camera from its rig elements and animate the camera object free of any constraints. Note that animating the scaling of the camera has no effect.
When working with a "free" camera (not using the default camera rig), you can select a camera and animate its transformations as you would any other object in Softimage. As long as the camera is selected, you can also have Softimage automatically set keys (autokey) as you transform the camera. For more information, see and [ ].
By default, navigating the camera while autokeying does not set keys on the camera parameters. This is because the camera is typically not selected and the corresponding parameters are not marked during navigation. However, you can set up specific cameras and spotlights so that their parameters do get keyed automatically during navigation. For details, see [ ].
When using , you can animate a camera's interest to make the camera follow a path or object. Animating a camera's interest is the easiest way to keep any action in the scene in frame. The two most basic ways to do this are to set the interest on a path or to constrain it to an object in the scene.
When using , you can rotate the camera itself, but the camera rotation in the X and Y axes cannot be keyed because the camera is constrained to point at the camera interest. However, you can animate a camera's Z rotation by either deactivating its up-vector constraint or modifying its Roll parameter.
Although you can use the L key to roll a camera, you cannot mark it for animation as you would the scaling, rotation, or translation options. Instead, you must open the camera's constraint property editor and mark the Roll parameter from there.
In an explorer, make sure that you have selected Show All Nodes and expand the Camera icon (and not the Camera Root or Camera Interest). Expand it until you find the Camera Kinematics Constraints Direction Cns icon.
On the Up Vector tab, activate the Up Vector and use the Roll parameter to control how much you want the camera to roll. A negative value makes the camera roll to the left and a positive value makes the camera roll to the right.
If you wish to further edit the roll of your camera, you can edit the Roll parameter's function curve. To do this, right-click on the animation icon and choose Animation Editor. The function curve for the Roll parameter appear in the editor and you can animate to your heart's content.
