编辑

变换

参考

模式: 编辑模式
菜单: 键 ‣ 变换

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.

比率: 删除定义比例的关键帧，要删除的关键帧数量由删除属性定义。
边际误差: Deletes keyframes which only allowing the F-Curve to change by a defined amount. The amount of change is controlled by the Max Error Margin which controls how much the new decimated curve is allowed to deviate from the original.

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.

../../../_images/editors_graph-editor_fcurves_editing_clean2.png — 清理后的函数曲线。

清理通道

参考

菜单: 键 ‣ 清理通道
快捷键: X

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).

平滑关键帧

参考

菜单: 关键帧 ‣ 平滑关键帧
快捷键: Alt-O

还有一个选项可以平滑选定的曲线，但要注意：它的算法似乎是将每个关键帧之间的距离和曲线的平均线性值除以2，而不进行任何设置，这样可以提供相当强的平滑效果！请注意，此工具似乎永远不会修改第一个和最后一个键。
