Cameras in FaceFX Studio have the following properties:
Hold Alt to move the camera to a new position. Use LMB, MMB and RMB.
Hold Ctrl+Alt to move a named camera to a new position.
To associate a camera with a workspace, select the camera with the workspace selected. From then on, selecting the workspace will also select the camera.
Binding a camera to a bone is useful for keeping the camera on the face while the head is moving.
Using a fixed aspect ratio is useful when you want to use the camera with a workspace and you want the sliders to remain on a particular region of the face. The downside is that face will get skewed depending on the size of the render window.
FOV is useful for cameras that are close to the face to prevent distortion.
Near Clip Dist. determines how close you can get to the character before it is no longer visible.
Far Clip Dist. determines how far away you can get from the character before it is no longer visible.
