简介

The NonLinear Animation editor, or NLA editor for short, lets you animate on a higher level. Instead of working with individual keyframes, it works with actions, which are named, reusable animation segments.

主区块

The editor displays a stack of tracks which work like layers in an image editing program. Higher tracks take precedence over lower ones, although you can also choose to blend them.

Each track can contain any number of strips — typically Action Strips, which are instances of actions.

The top track hilighted in orange is special: this is the Action Track. Unlike the other tracks, it doesn’t contain strips — instead, it contains the object’s active action, which is where new keyframes are added to by default.

Editors like the Timeline and the Dope Sheet Editor normally only show the keyframes of this active action. If you want to edit another action, you can select it in the NLA editor and press Tab to enter Tweak Mode.

Tweaking an action. Notice that it’s shown in both its original track and the Action Track. The active action is temporarily hidden.

实时更新

Whether to update other views (such as the 3D Viewport) while you’re moving strips around. If disabled, the other views only get updated once you finish the move.

显示函数曲线的控制

Shows a graph on top of each strip that uses Animated Influence.

显示标记

Shows the marker region (provided any markers have been defined). When disabled, the Marker Menu is also hidden and marker operators are not available in this editor.

显示自身标记

Shows action-local markers (which you can create in the Action Editor). This can be useful to align strips to each other.

显示为秒 Ctrl-T

以秒显示时间而不是以帧显示。

同步可见范围

Synchronizes the horizontal panning and scale of the editor with other time-based editors that also have this option enabled. That way, they always show the same section of time.

设置预览范围 P

Lets you drag a box to define a time range for previewing. As long as this range is active, playback will be limited to it, letting you repeatedly view a segment of the animation without having to manually rewind each time.

You can change the start or end frame using the corresponding button in the Timeline editor’s Playback popover. Alternatively, you can simply run Set Preview Range again.

清除预览范围 Alt-P

设置被选的预览范围 Ctrl-Alt-P

标记菜单

Markers are used to denote frames with key points or significant events within an animation. Like with most animation editors, they’re shown at the bottom.

数据块排序

Sorts data-blocks alphabetically to make them easier to find.

If your playback speed suffers because of this (should only really be an issue when working with lots of objects), you can turn it off.

吸附

The toggle button enables/disables automatic strip snapping. The dropdown button shows a popover with the following options:

吸附至

元素的吸附类型。

  • 帧/框:

    Snap to full frames.

    秒:

    吸附到秒。

    最近标记:

    吸附至最近的标记。

绝对时间对齐

When disabled, strips will move in increments of Snap To. For example, if you selected Second and have a strip that currently starts on 0:06+5, dragging it to the right will snap it to 0:07+5. Its time increases by a second, and its subsecond offset of 5 frames remains the same.

When enabled, strips will snap to multiples of Snap To. Taking the above example, the strip would snap to 0:07+0, removing the subsecond offset.
