Giới Thiệu -- Introduction¶

The NLA editor, short for NonLinear Animation, can manipulate and repurpose Hành Động -- Actions, without the tedium of handling keyframes. It is often used to make broad, significant changes to a scene's animation, with relative ease. It can also repurpose, chain together a sequence of motions, and "layered" actions, which make it easier to organize, and version-control your animation.
