Create facial expressions in Animation View

(Updated 07/12/2021)

This section describes the steps for creating facial expressions in the Animation View.


Setting Scenes

First, create a new animation file.
Create a new scene from the [File] menu -> [New] -> [Animation].
A project file name that is easy to recognize as an expression, such as “(character name)_exp.can3” is recommended.

First, go to the [Inspector] palette to set up the settings for expression motion.

Scene name:

The scene name will eventually be listed in the JSON file, so the name should be consistent with the specification.


The tag section should include the name of the expression for easy identification.


Since there is no movement in the expression, the shortest length is fine.

However, since the timeline must be longer than 2 frames when the motion data is exported, set the scene length to “2”.
If the length is not long enough (one frame), the following warning dialog box will appear.


The length time notation can be switched between “timecode format” and “frame format” by pressing the icons in the [Timeline] palette.

Loading the model

Drag and drop models onto the [Timeline] palette to place them on the view.
For more information on loading model files, see “Loading and Placing Models”.

Then adjust the model size.
Place them in a size that makes it easy to recognize their expressions, as shown in the figure below.


How to add facial expressions

Key frames will be hit only on the parts related to facial expressions.
Keyframes are not used for areas unrelated to facial expressions, such as the “angle of the face (XY)” or the “swing of the hair”.

Also, among facial expressions, parameters that may be moved by motion, such as “mouth open/close,” “eyeball X,” and “eyeball Y,” should be carefully considered when determining values.
Normally, these parameters should be left unchanged at their standard values.

(This depends on the specifications of the game or application, so please consult with our development staff before making a decision.)




Export Motion Data

Once the facial expression scene has been created, click on the [File] menu -> [Export Embedded File] -> [Export motion file] to export the motion3 file.
If there is no particular reason, export with the following settings.


For instructions on how to import motion3 files for facial expressions into the Viewer, please refer to “Facial Expression Settings and Export”.
