An F-Curve can be edited by transforming the locations of the keyframes.

移动，旋转，缩放

与 Blender 中的其他元素一样，关键帧可以如同基础变换中描述的一样移动、旋转或缩放。

添选

Moves keyframes relative to the current frame. If the mouse is to the left of the Playhead, this operator only affects the selected keyframes that are to the left of the Playhead. On the contrary, if the mouse is to the right of the Playhead, this operator only affects the selected keyframes that are to the right of the Playhead.

Slider Operators

Breakdown

参考

菜单

Key ‣ Slider Operators ‣ Breakdown

Moves the selected keyframes to an in between position relative to the adjacent keyframes. To use this operator, drag the mouse left or right to adjust the operator’s Factor property.

系数

The amount to favor either the left or the right key. Values less than 0.5 favor the left keyframe, values greater than 0.5 favor the right keyframe, a value of 0.5 results in no change.

Blend to Neighbor

参考

菜单

Key ‣ Slider Operators ‣ Blend to Neighbor

Transitions the current keyframe with the neighboring keyframes in the timeline. In order for this operator to work, there must be a keyframe before and after the current frame. To use this operator, drag the mouse left or right to adjust the operator’s Blend property.

混合

The amount to favor either the left or the right key. Values less than 0.5 favor the left keyframe, values greater than 0.5 favor the right keyframe, a value of 0.5 results in no change.

Blend to Default Value

参考

菜单

Key ‣ Slider Operators ‣ Blend to Neighbor

Transitions the current keyframe towards the property’s default value. To use this operator, drag the mouse left or right to adjust the operator’s Blend property.

清理通道

参考

菜单

键 ‣ 清理通道

快捷键

Acts like the Clean Keyframes tool but will also delete the channel itself if it is only left with a single keyframe containing the default property value and it’s not being used by any generative F-Curve modifiers or drivers.

Note

The modified curve left after the Clean tool is run is not the same as the original, so this tool is better used before doing custom editing of F-Curves and after initial keyframe insertion, to get rid of any unwanted keyframes inserted while doing mass keyframe insertion (by selecting all bones and pressing I for instance).
