You can deactivate (mute) a function curve so that its animation has no effect on the object. Muting a function curve doesn't remove it from the object, it just temporarily disables it.

You can also mute function curves in the dopesheet, including regions of the function curves. For more information, see Deactivating (Muting) Animation in the Dopesheet.

To mute function curves:

1. Select one or more function curves.

2. Choose Curves Deactivate Curve from the fcurve editor command bar.

   The curves appear as dotted lines. When you deselect them, they are dotted lines in their usual color (such as blue for Z-axis transformation fcurves).

   You can select the muted curves and edit them as you would normally.

   

   Muted fcurve appears as dotted line when selected or not (as shown here).

To activate muted function curves:

1. Select one or more muted function curves.
