Introduction¶

The NLA editor, short for Non-Linear Animation, can manipulate and repurpose 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.

Start Editing Stashed Action

It will enter and exit Tweak Mode as usual, but will also make sure that the action can be edited in isolation (by flagging the NLA track that the action strip comes from as being « solo »). This is useful for editing stashed actions, without the rest of the NLA Stack interfering.

Start Tweaking Strips Actions

The contents of Action strips can be edited, but you must be in Tweak Mode to do so. The keyframes of the action can then be edited in the Dope Sheet.
