Use On/Off when you
want to work with the original function curve rather than a curve
altered by ease and multiplier curves. A disabled curve has no effect
on its assigned track, but can be enabled to restore the effect.
To toggle the active state of an ease
or multiplier curve:
- In the Hierarchy list, highlight one
or more ease or multiplier curves.
- From the Curves menu choose On/Off.
If you also have the
parent track selected (the transform that has the ease applied),
you will see the difference in the curve when you turn the ease
or multiplier off.
