FOV Adjustments box Select an FOV camera adjustment mode.
To:Select:
Use all corner keyframes to compute an overall FOV and set the camera to non-animated during
tracking of the perspective grid. By using multiple keyframes of corners, this is a better estimate of
FOV (for sequences where FOV does not change).
Static
Allow adjustments of the target camera FOV and position during tracking of the perspective grid.
Use when the FOV changes over the length of the sequence.
Dynamic
Lock the camera FOV and position during tracking of the perspective grid.Lock

Magnifier button Enable to display the magnifier while dragging a corner of the perspective grid rectangle.
Zoom field Displays the zoom factor of the magnifier. Editable up to 5x.
Display Grid button Enable to display the grid lines in Result or Object view.
Grid Colour pot Displays the colour of the grid lines. Click to change the colour.
Action Lights and Lighting Effects
When you enter Action, you can activate a global shading option (from the Rendering section of the Action
Setup menu) to light your complete scene. Once you add a light to the scene, the shading becomes active,
and you can also enable Scene Ambient lighting from the Rendering section of the Action Setup menu, or
in individual Light menus. Action objects are lit up in the scene according to the number, position, direction,
and colour of added light sources, as well as the rotation and spread of each light source.
Action lights also serve as the parent node for a number of lighting effects, such as lens flares, rays, and
shadow casts.
Keep in mind the following when working with Action lights:
■ You can add up to 64 active light sources to a scene. You can also control each light individually.
■ You can set individual lights to different types, such as spotlights or area lights. Ambient is also available
as an individual light type, and is different than the global Scene Ambient lighting.
■ Use the Action Object Solo (F8) view on a light to see the scene through the point of view of the light,
as if it was a camera.
■ Similar to cameras in Action, you can set a Free or Target light mode. Select Free to light the scene in the
direction that you aim the light, or Target to aim the light at a target object in the scene based on a point
of interest. Different settings are available in the Light menu based on the choice of light mode.
■ You can attach a
look-at connection (page 466) between Action objects with axis characteristics (Axis,
Camera, Light). The connection allows the parent object to rotate to face the child look-at object, no
matter where it is positioned. Look-At links can be animated; therefore you can link different objects
from the parent at different frames. In the channel editor, you can see a lookAt channel for every look-at
parent.
■ By default, the light you add to the scene is applied to all surfaces. However, you can also apply a light
source to specific surfaces with inclusive and exclusive light links.
