The Non-Linear Animation Window
As with every window header, the first button allows you to set the window type.
Maximise the window, or return to the previous window display size; return to the previous screen setting (Ctrl↑).
All visible blocks are displayed completely, centered in the window (↖ Home).
This button locks the update of the 3DWindow while editing in the NLAWindow, so you can see changes made to the Action in realtime in the 3DWindow.
The NLA Window gives a full overview of all the Objects that have had action strips added to the NLA editor and allows a very fine and flexible control of each action, effectively allowing for action blending somewhat akin to how Relative Vertex Keys work on meshes.
The NLA window presents the time, in frames, on the horizontal axis and one strip for each object, each strip can have as many action substrips as desired.
It is important to have unlinked any normal Action from the armature when working with NLA because normal actions take precedence over NLA controls.
Sets current frame.
The view is translated.
Zoom in or out of the NLAWindow, this happens only horizontally.
Select an Armature Strip (if clicked on strip name) or an Action Strip (if clicked on it). Use ⇧ Shift to enlarge or reduce the selection (extend select).
Add/remove from selection.
All visible blocks are displayed completely, centred in the window.
Select All / deselect All. If one block is selected, everything is first deselected. It behaves differently depending if the cursor is on the left (selects all armatures) or on the right (selects all actions) of the NLAWindow.
Add an action strip for the currently selected object.
Duplicates the selected Action(s). Duplicates are automatically in Grab mode and are assigned to new sub-strips.
Translation mode (the Grabber). This works on selected Actions and only horizontally, to change frame. The following options are available in translation mode:
- ↑, ↓, ←, →:
The mouse cursor can be moved exactly 1 pixel with these keys.
The Actions are displaced by 1 frame steps.
- ⇧ ShiftCtrl:
The Keys are displaced by 0.1 frame steps.
- Grabber terminates with:
- LMB , Space or ↵ Enter: Move to a new position.
- RMB or Esc: Everything returns to the old position.
Brings up the "Numerical" window settings for the selected Action.
defines the Action Strip placement. If the interval is greater than the actual Action duration, the Action is performed slower to match the required duration, otherwise faster.
defines the Action timeline "Windowing". The Actions are defined in their normal way and their duration is, by default, a "Window" of frames going from first to last key. With these sliders it is possible to vary the Action "Windowing".
defines a number of frames at the beginning and at the end of the strip of "Reduced influence" of the Action. By carefully setting these and by letting action strips slightly overlap, you can fluidly blend different actions.
- makes the strip contain as many copies
of the action as desired. Great for Walkcycles.
- in Walkcycles defines the length (in Blender Units) of
- makes Blender use the Path to which the armature
is parented, and its length, to make the Armature move according to Stride definition.
- the last pose forever, instead of reverting
to the original state.
- makes Blending additive.
Delete selected Actions.
