What's New 4.1

(Updated 06/10/2021)

Live2D Cubism gets a major update to version 4.1!
Please see below for a detailed description of the new features.


Temporary deform tool

A temporary deformation tool has been added to allow more convenient deformation of selected objects.
It can be performed on objects with vertices, so deformations can be performed on deformers, and
only selected vertices can be deformed.

It can also be used for form animation (FA) since it does not modify the model data structure.


Temporary path deformation

You can create a disposable deformation path that allows you to deform the vertices of the selected object.
It can be deformed to bend along a path.


Temporary warp deformation

A grid of control points allows you to deform the vertices of the selected object.
It is also possible to edit the grid by increasing or decreasing its columns and rows according to the situation.


Other Temporary Transformation Tools

Objects with vertices can be deformed in various ways.
The following deformations are supported, allowing you to efficiently create the shape you want to make.

  • Enlarge/shrink
  • Rotation
  • Free transform
  • Perspective
  • Distort


Stroke ArtPath / Re-stroke ArtPath

This function creates and edits ArtPath to match the stroke.
ArtPath can be placed in line with strokes drawn with pen tabs, etc., as if they were drawn directly on the canvas.

It is also useful for redrawing ArtPath.


Stroke mesh-mapping (beta)

Added the ability to create a mesh with strokes in mesh edit mode.
Dragging the canvas creates a path from which a mesh can be created.

The polygons of the ArtMesh are divided by tracing the area to be meshed.



Deformed brush (beta)

This tool allows you to intuitively deform ArtMesh, ArtPath, and warp deformer shapes with a brush.
Select an object and drag the area you want to deform to deform it.


Timeline Improvements

Dopesheet and graph editors have been greatly improved.
Major modifications have been made to the editing of Bezier curves, mainly in the Graph Editor.


Graph editor

Self-adjusting handle:
In Bezier curve editing, the front and rear handles now extend and retract to prevent the curve from bending through.
It also expands and contracts in the same way when moved on the dope sheet.

Continuous Beziers:
Edit so that the front and rear handles are aligned.
Useful for adjusting smooth curves.

By default, holding down [Ctrl] and moving a handle will result in continuous bezier editing, but you can also change
the default setting by checking the [Always edit continuous Beziers] in the [Palette Menu] in the upper right corner of the timeline palette.
(Press [Ctrl] to reverse the function.)

Box Editing:
Keys no longer disappear when transforming a box in the selected state.
Narrowing the width of the box will place the keys as close together as possible.

In addition, the original shape is remembered until the box disappears, so curve information is not lost even if the box is repeatedly deformed.

Copy and Paste:
Copy and paste can now be used within the graph editor.
One curve can be pasted into any other curve at any position across scenes and animations.
In the case of multiple curves or form animation curves, the curves are limited to the same curve.

Edit curves by dragging:
It is now possible to grab a curve and edit its shape.
It is useful for creating rough shapes.

Curve Preset:
Frequently used curve shapes can be applied to a specified curve at the touch of a button.
This is a useful function that can also be utilized for character movement, although it is often used primarily in motion graphics.

Smoothen curve:
Shapes the handles before and after the selected point into a straight line (continuous Bezier).
It can be selected from the right-click menu and applied to a selection key or to the entire selection curve.

Enable smart snap:
Round the value
of the selected points.

Display parameter name at key position:
If the [Display key name] checkbox in the Timeline menu is checked, at the key position in the graph editor,
the name of the parameter will be displayed.

Dope sheet

Key additions:
In the case of Bezier curves, handles are automatically created while preserving the curve shape as in the Graph Editor.

Change of value:
When editing with the parameter slider, the original shape is maintained as much as possible, even if the handle reaches the upper or lower limit until a decision is made.

Increase parameter input accuracy:
Editing Live2D parameters while holding down [Shif] allows you to enter detailed values.
This function is useful when fine adjustments are required.

Form Animation Key Moves:
Adjust the values so that the curve editing limited to form animation maintains a base point value (the same value as the frame value) that reflects 100% of the deformation when the key is moved.

Improved UI operation in heavy environments:
Operability during heavy model editing has been improved.


Scene track

  • This function places a scene as a track within another scene.
    Scenes can be used as materials or multiple scenes can be joined together to create an animation.
    Scenes can also be nested by placing scenes containing scene tracks as scene tracks.
  • Apply a time remap to the scene track to speed up, slow down, or reverse the playback of the referenced scene
    • Easing and other effects can be added.
    In addition, by placing the created scene as a scene track and applying a time remap, the overall movement of the
    Tame and Tsume can be adjusted.
  • The scene track has a repeat function, allowing the referenced scene to be played back repeatedly.
    It can be used to repeatedly display short scene material, such as simple effects or screen superimpositions.


Scene import

The ability to copy and add part or all of a scene from another animation file.
Reference information for materials such as models and image files is also copied as needed.



Onion skin (official version)

The onion skin feature, which has been available as a beta version since Cubism 4.0, is now released as an official version.
In addition to the substantial addition of configuration items, improvements have been made in terms of ease of use, including access to functions.


Onion Skin Activation

A button added to the bottom of the view area allows the onion skin to be turned on and off without having to open it from the menu.
The ON/OFF status is linked to the open view ([Modeling], [Animation], [Form Animation]).


Modeling View Display Settings

The modeling view allows the following settings.

Image/Orbit display of the currently selected vertex:
In the beta version, it was only possible to switch the display of the orbit of the selected vertex, but from the official version, the image of the onion skin and the display of the orbit
can now be switched independently.
In the beta version, the orbit of the selected vertex was displayed only in the ArtMesh, but from the official version, the control point of the deformation path
are also supported.

Color and transparency settings:
Onion skin color and transparency settings are also available in the modeling view.

Onion skin layer in the foreground:
When checked, the onion skin layer is always displayed in front of the other parts, and when unchecked, it
is displayed in its original drawing order.


Onion Skin Marker

Onion skin markers are special markers that are placed at any frame position on the timeline palette to set the display position of the onion skin.
Onion skin markers can be moved by mouse dragging.



Visualize the display range of the onion skin on the timeline

A red bar has been added to indicate the range of frames in which the onion skin will be displayed.
The length of the onion skin display range bar is linked to the display range of the frame to be displayed (see below) and the previous and next frames in the onion skin settings.

The red bar displaying the onion skin range can be toggled between [All Frames], [Key Frames], and [Onion Skin Markers].



Animation View Display Settings

The following settings are available in the animation view.

Display during playback:
The onion skin display can now be toggled on and off during animation playback.
This is useful if you want to reduce the drawing load during playback while the onion skin function itself is turned on.

Onion skin layer in the foreground:
When checked, tracks in the onion skin are always displayed in front of other tracks; when unchecked, tracks are displayed in their original drawing order.

Displayed in:
The target frame for displaying the onion skin can now be selected.

Opacity downside:
The opacity of onion skin frames can now be set to decay as one moves away from the current position.
The lowering range can be set in 10 steps.

A setting to shift the drawing position of the onion skin in the X and Y directions has been added.
This function is useful when you want to check the previous and next frames on a track with few coordinate shifts.

Form animation view display settings

The following settings are available in the form animation view.
* Both are almost the same function as the setting of the same name added to the Animation View.



Other Improvements

Hide selected state

Click on the [View] menu -> [Hide selected state].
When an object is selected on the canvas, the UI (ArtMesh vertices and mesh lines, deformer border lines) are hidden.
Shortcut keys can also be used to hide the UI on the view that appears in the selected state.



Put selected objects into children

A new option (check box) [Include selected objects as children] has been added to the Create Part dialog.
[Put selected objects into children] is enabled when

  • Multiple object selection
  • When executed from a shortcut, regardless of the number of selected objects
  • When [Shift] + left click on the New Part icon



Paste shapes to different objects

For objects such as ArtMesh and warp deformers, if the number of vertices is the same, you can use [Copy Shape] on another object
to paste.

If the objects are of the same type and have the same number of vertices and control points, they can be pasted.
For ArtPath, the shape can be pasted along the copied shape even if the number of vertices do not match.



Parameter Duplication

Added [Replicate parameters] function to the right-click menu of parameters.

Duplicate parameter settings only.
(Objects and key forms are not duplicated)



Change automatic layout of texture atlas editing

Automatic layout of texture atlas editing can now be configured to fix magnification, allow rotation, etc.
In addition, while previously it was only possible to automatically place images so that they did not overlap, we have added a setting that allows mesh to be placed in such a way that they do not overlap.


Gather files

Copy and export the animation file along with the material being used.
It can be used to archive animations and pass them on to other workers,
to avoid accidents such as loss of material files or broken links.



Solo display function

This function allows you to solo only the target track on the timeline palette.
By pressing the [Solo Display Button] added to the right of the track's display button (eyeball button), only that track can be displayed alone.



Change by dragging the display and lock buttons

The [Track display] and [Lock] buttons on the Timeline palette can now be continuously toggled by dragging.
Buttons on multiple tracks can be switched on and off more quickly.


[OW Viewer] Display of curve type for motion

[OW Viewer] The function to reproduce motion playback of SDKs prior to 4.0 has been added.
If you are using the SDK (Others) in the target version, please consult with the developer and consider whether to check the box.

For more details, please refer to the page “Degradation of motion3.json reproducibility” in the [Cubism SDK Manual].


[OW Viewer] Cursor tracking setting function

The Viewer can now do exactly the same thing as the [Cursor Tracking Settings] in the Editor's Physics and Scene Blend Settings dialog.


Some icon and cursor design changes

The following icons in the [Mesh Edit Tool] under Manual Mesh Editing have been redesigned.
(The cursor used to change the icon design is also changed.)

(1) Increase the number of vertices
(2) Stroke mesh-mapping (beta)

The following icons in the [ArtPath Tools] have been redesigned.
(The cursor used to change the icon design is also changed.)

(1) Adjust the opacity set on the control point.
(2) Adjust the width of control point
(3) Stroke ArtPath
(4) Re-stroke ArtPath
