Procedures
To set normalize time for a key:
1 Select an object and choose a key to Normalize.
You can use the arrows in the Key Info (Basic) rollout to step through
Keyframes.
2 In the Key Info (Advanced) rollout, click Normalize Time.
The key is moved in time to average the velocity through the key.
Interface
In/Out The In field is the rate of change as the parameter approaches the key.
The Out field is the rate of change as the parameter leaves the key.
■ These fields are active only for keys using the Custom
tangent type on
page 3129.
■ The number in the field is the rate of change expressed as parameter units
per tick. By changing the two values for X, Y, and Z you are changing the
length and angle of the tangent handle.
Lock button Changes one Custom tangent by changing the other an equal
but opposite amount. For example, if you click the Lock button and the In
value is 0.85, then the Out value is -0.85.
Normalize Time Averages the position of the keys in time and applies them
to any consecutive blocks of selected keys. Useful if you have an object that
speeds up and slows down repeatedly, and you want to smooth out the motion.
