Channels

Channels Region

The Channels region.

The channels region is used to select and manage the curves for the Graph editor. This part shows the objects and their animation data hierarchy each as headers. Each level can be expanded/collapsed by the small arrow to the left of its header.

• Scenes, Objects (dark blue)

• Actions, Shape keys, etc. (light blue)

• Groups (green)

• Channels (gray)

Name Filter Ctrl-F

Only displays channels that match the search text. Pressing the invert button displays all channels except the channels that match the search text.

Controls

On the headers, there are toggles to control channel's setting:

Pin (pin icon)

Make the channel always visible regardless of the current selection (Graph editor only).

Hide (eye icon)

Hides the channel(s)/curve (Graph editor only).

Modifiers (wrench icon)

Deactivates the F-Curve modifiers of the selected curve or all curves in the channel.

Mute (speaker icon)

Deactivates the channel/curve.

Lock (padlock icon) Tab

Toggle channel/curve from being editable. Selected channels can be locked by pressing Tab.

ملاحظة

In the Dope Sheet this is also working inside the NLA, but that it does not prevent edition of the underlying F-Curve.

Extrapolation Mode

Reference

Shift-E

Change the extrapolation between selected keyframes.

Extrapolation defines the behavior of a curve before the first and after the last keyframes.

There are two basic extrapolation modes:

Constant

Constant extrapolation.

The default one, curves before their first keyframe and after their last one have a constant value (the one of these first and last keyframes).

Linear

Linear extrapolation.

Curves ends are straight lines (linear), as defined by the slope of their first and last keyframes.

Additional extrapolation methods (e.g. the Cycles modifier) are located in the F-Curve Modifiers.

Show/Hide

Hide Selected Curves H

Hides the selected curves.

Hide Unselected Shift-H

Show only the selected curve (and hide everything else).
