Properties & Modifiers¶
Properties¶
Strip properties can be accessed via the NLA Properties region.
Animation Data¶
Animation Data panel
- Context
- ToDo.
- Action
- Data-Block allows you to edit actions shown in the action track. See also the Action Editor’s Action.
- Action Extrapolation
Action to take for gaps past the strip extents.
- Hold
- Affects both sides of the strip.
- Hold Forward
- Affects the region after the clip, only.
- Nothing
- Neither.
- Action Blending
Affects the behavior when two tracks simultaneously have a curve affecting the same property.
- Replace
- Causes the top strip to take precedence according to the parameters of the Blend In/Out (see next option, below).
Multiply, Subtract, Add
- Action Influence
- ToDo.
Active Track¶
- Name
- Name of the track which the strip currently belongs to.
Active Strip¶
Active Strip panel
Options of the strip itself.
- Name
- Renames the strips.
- Type
- Will either say “Action Clip”, “Transition”, or “Meta”, according to the three types of strips.
- Strip Extents
- The boundaries of the strip itself. Note that this will stretch the duration of the Action, it will not cause greater or fewer keyframes from the Actions to play (see below for that option).
- Extrapolation
- See Action Extrapolation above.
- Blending
- See Action Blending above.
- Auto Blend In/Out
- Creates a ramp starting at the overlap of the strips. The first strip has full control, and it ramps linearly giving the second strip full control by the end of the overlapping time period.
- Blend In
- Set the frame that represents when this strip will have full influence.
- Blend Out
- Set the last frame of this strip’s full influence.
- Muted
- Mute a single strip (like muting the track, above). Causes the track outline to be dashed.
- Reversed
- Cause this strip to be played completely backwards.
Action Clip¶
Action Clip panel
This represents the ‘object data’ of the strip. Much like the transform values of an object.
- Action
- A reference to the Action contained within the strip. Can be changed to replace the current strip’s value with another Action.
- Action Extents
How much of the Action to use.
Note: If you select values that are above or below the actual keyframe count of the Action, then the F-Curve Extrapolation will be consulted. Which can be changed in the Graph Editor, under .
- Sync Length
- Causes the “Start” and “End” Frames, above, to be reset to the first and last keyframed frames of the Action.
- Sync Action Length “Now”
- Causes the “Start” and “End” Frames, above, to be reset to the first and last keyframed frames of the Action.
- Playback Settings
- Scale
- Stretches strip, another way of increasing the Strip Extents: End Frame, above.
- Repeat
- Also expands the strip, but by looping from the first keyframe and going forward.
Evaluation¶
Evaluation panel
This determines the degree of influence the strip has, and over what time.
- Animated Influence
Enabling alteration of the degree of influence this strip has as a keyframable value. If influence isn’t animated, the strips will fade linearly, during the overlap.
These can be found in the Dope Sheet or Graph Editors under the NLA Control Curves and look like group channels. They appear before all the groups/FCurves for that channel.
- Animated Strip
- Same as Animated Influence, but with Strip Time.
- Cyclic Strip Time
- Cycle the animated time within the action start and end.
Modifiers¶
Like its close cousins in mesh and graph editing, Modifiers can stack different combinations of effects for strips.
See F-Curve Modifiers.
