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.

主要区块

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.

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

Local markers shown in the NLA Editor (top) and the Action Editor (bottom).

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.

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.
