Key Behaviours

The "Keys" menu of the "Curve Editor" provides several methods to continue a curve before the first or after the last animation key:

Zero

The parameter's value is set to 0 before the first or after the last key to continue the curve.

Constant

This function uses the first or last key's parameter value to continue the curve.

Loop

This function creates an endless repetition of the curve segment between the first and the last key to continue the curve.

Loop Offset

This function creates an endless repetition of the curve segment between the first and the last key to continue the curve: the values are added and the result is a growing or declining curve.

Follow Tangent

This feature uses the last key’s tangent gradient to continue the curve.
