As the aircraft travels along the motion path, its orientation remains the same throughout the animation. A real aircraft rolls to one side (banks) as it flies in an arc. To make the aircraft roll to one side as it travels along the path you set keyframes for the Twist attributes in the Channel Box.
To animate the roll of the aircraft along the path
- Ensure the aircraft is selected.
- Set the Time Slider to frame 120.
The aircraft is repositioned along the curve near the first bend.
- In the Inputs section of the Channel Box, click on motionPath1 to view its attributes.
- Ensure the Front Twist value for motionPath1 is set to 0.
- Select the Front Twist channel, then right-click and select Key Selected.
- To set the remaining keyframes for the rotation of the aircraft, use the table below as a guide, keeping in mind that you set the keyframes in the following order:
- Set the frame in the Time Slider
- Set the values for Front Twist in the Channel Box.
- Select the Front Twist channel by clicking its name, then right-click and select Key Selected.
