6 Click the Assign Controller button and choose TCB Rotation then
click OK.
TCB Rotation will allow you to rotate objects on their Local axes as
opposed to the World axes. This is beneficial when you have an object
that is rotating on an axis that is tilted, such as the rotational axis of a
planet.
7 Select Mars, then click Select And Link. Drag the rubber band
to MarsControl. Release the mouse button when the cursor changes.
8 Link each of the moons, Deimos and Phobos, to MarsControl.
Mars and its two moons are now linked to MarsControl. Any movement
or rotation you make to MarsControl will affect all the planetary bodies.
9 Click Select And Rotate, and select MarsControl.
10 Change the Reference Coordinate System
from View to Local.
11 Turn on the Auto Key button and move the time slider to
frame 100.
12 In the Z axis field, below the time slider, enter 60.
This rotates MarsControl by 60 degrees around its local Z axis. Because the
planet and moons are linked to MarsControl, they also rotate.
