Physics and scene blend settings

(Updated 06/16/2022)

The [PHYSICS/SCENE BLENDING] settings include two setting screens: [Physics] and [SCENE BLENDING].
The settings screen can be switched by tabs.

 

How to switch setting screens

Click on the tabs in the red framed area of the image to switch screens.

 

 

Physics setting screen

Set up the physics calculation settings for hair swaying, clothing swaying, and so on.
See “Physics Settings” for a detailed explanation of physics settings.

 

 

Scene blend setting screen

Scene blending settings allow you to play back scenes created with animation files.
In addition, multiple scenes can be blended together for playback.
See “Scene Blend Settings” for a detailed description of scene blend settings.

(2)

Playback bar

Playback of playlists set in scene blending, fades during scene transitions, and FPS settings.

(3) Parameter list The parameters that have already been created for the model are listed.
During cursor tracking and scene playback, the parameter values are reflected in the slider in real time.
If Physics is enabled, the calculated results are reflected in the slider in real time.

Item Detail
Undo Restores the state immediately before the last operation.
Shortcut key [Ctrl] + [Z]
Redo [Undo] executes the operation performed before going back one step.
Shortcut key [Ctrl] + [Y]

 

Physics Menu

Item Detail
Loading physics settings Load the file physics3.json.
Export Physics settings

Write out the physics3.json file.
See “Data for Embedded Systems” for exported data.

For FPS information:
FPS information will be exported only when a confirmation dialog box appears and [Yes] is selected.

Importing Presets Import input/physical model setting presets.
Exporting Presets Export input/physical model setting presets.
Initialization of input presets Initializes the input preset. Please note that the presets you have created will also be erased.
Initialization of physical model presets Initializes the physical model preset. Please note that the presets you have created will also be erased.
Initialize calculation FPS Initialize the list of calculated FPS.

 

Scene blending menu

Item Detail
 cmo3 and can3 linkage settings Set the linkage settings for the animation file (can3) to be loaded into scene blending.
See “How to Setup Scene Blending” for details on the linkage settings.

TIPS
In the cmo3/can3 linkage setup, it is not possible to load multiple can3s at the same time.
For example, scenes separated by can3, such as “Expression.can3” and “Motion.can3,” cannot be combined for playback.
Prepare scenes within the same can3 for the facial expressions and motions you wish to combine in scene blending.

 

Preview Menu

Item Detail

Setting up a hit decision

When checked, the set hit criteria will be visualized as a red frame.
Please refer to “Preparation for Bingo Settings” for more information about the Bingo settings.

Cursor tracking

If checked, the model will follow the cursor by dragging on the view.
* Operates during scene playback.
The direction and parameters for tracking can be set from [Cursor Tracking Settings] described below.

Automatic eye blink

When checked, the model will blink automatically.
Blink is applied to the parameters set for blink in the model's [Settings for Eye Blinking and Lip-sync].

Breath

When checked, the model breathes automatically.
Breath applies values to parameters whose parameter IDs are “PARAM_BREATH” or “ParamBreath”.

Cursor tracking settings

Impact (%):
The degree of influence can be set to affect the movement of the parameter.
A stronger setting will result in a larger movement, while a weaker setting will result in a smaller movement.

Reflect: The cursor tracking is inverted.

Type:
Set the type of parameter you want the cursor to follow.
• In the case of left mouse dragging
(Left mouse X: horizontal movement, Left mouse Y: vertical movement)

• In the case of right mouse dragging
(Right mouse X: horizontal movement, Left mouse Y: vertical movement)


Cursor tracking settings are saved in the model data (cmo3) but are not exported to the embedded data.
If you want the cursor to follow when embedding, configure the settings on the SDK side.

* The cursor tracking setting can also be checked in [OWViewer].

Random Pose Setting

Opens the Random pose Settings dialog.
See “Random pose” for details on operations and settings.

Recording Settings

You can select where to add scenes generated by the [Record] function.

Generate new animation data:
Create new animation data (can3).

Add to current animation data:
Add a scene to the animation data (can3) currently associated with it.

Playback bar and view area

Playback bar

Number Item Detail

(1)

Enable Physics

Unchecking the box temporarily turns off the physics setting.
For more information on the Physics Settings Editor, see “Physics Settings.

(2)

Playlist Selection

Playlists created on the Scene Blend Settings screen can be selected.

(3)

Scene Selection

You can select a scene from the selected playlist.
The following movements can also be confirmed.
• Random A
• Random B
• Random pose

(4)

Playback

Play the selected scene.

(5)

Repeat

When enabled, repeat playback of a scene is performed.

(6)

continuous playback

When enabled, all scenes in the playlist are played back continuously.

(7)

(Video) recording

Records the state of the view and generates a scene.
Recorded scenes are generated after the [Physics and Scene Blend Settings] dialog is closed.

(8)

Recording Settings

You can select where to add scenes generated in [Recording].

(9)

Fade

When repeat playback or continuous playback is enabled, a fade can be applied during scene transitions.

None:
Transitions to the next scene without fading.

Linear:
After the scene is played, a linear blending transition is made between the model state and the next scene during the scene's fade time.

Easing (2.1 method):
After the scene is played, during the fade time of the scene, a curved blending transition is made between the state of the model and the next scene. Blending can be set not only between motions, but also individually for each parameter.

Easing is applied to the weight when blending, resulting in a smooth transition impression.
* Unity can also disable Cubism fades.

(10)

Fade time (ms) adjustment

When fade is enabled, you can set the time to apply the fade. (1 second in 1000 ms)

(11)

 

Computational FPS

Sets the frame rate at which physics operations are performed.
You can choose from the following four types of FPS.
15 / 30 / 60 / 120

Also, entering a numerical value allows the FPS to be set to an arbitrary value and registered in the list.
To reset the list to its initial state, use [Initialize Calculation FPS] in the Physical Calculation menu.

By creating physics settings that match the FPS of the scene being used, it is possible to reproduce the scene without any sense of discomfort.

For calculated FPS:
FPS information is set in the model file by opening [Physics and Scene Blend Settings].
(The value of [Calculated FPS] will also be set in the model file at the time it is changed.)

FPS information is now stored in the model file starting with Cubism Editor version 4.1.02.
Model files created prior to 4.1.01 may not have FPS information set.
For more information on setting FPS information for model files, please refer to the SDK manual's “4.2 Functional Compatibility” page of the SDK manual for more information on setting FPS information for model files.
 

A note on Unity fades:
Mecanim in Unity uses the concept of layers to further blend the results, including motion fades.
Playback results in the Viewer are not a perfect reproduction of the Unity mechanism, so playback results may vary.
