About Cubism 4 New Features

[Last updated: 10/03/2019]

Cubism 4 has newly implemented the following functions: “Invert Mask,” “Frame Step,” “Extended Interpolation,” “ArtPath,” “Form Animation,” “Consecutive Image Track,” and “Onion skin”.
The table below shows the status of each of these functions in Cubism SDK.

Mask Inversion

This function inverts the area to be hidden by the mask.
For more information on mask inversion, click here.

Compatible with Cubism 4 SDK for all platforms.

Notes:
Because of modifications throughout the framework, updating a project built with the Cubism 3 SDK to Cubism 4 will require updating the entire SDK, not just the Core and shaders.

 

Frame Step

This function allows limited animation-like expressions to be created by continuing the same value as the current key until the next key without interpolating between keys.
For more information on frame step, please click here .

Notes:
When exporting from the editor to motion3.json, the Curve type of the parameter for which frame step is set is exported as Stepped .
Therefore, the exported motion3.json can be made to work with the Cubism 3 SDK.

 

Extended Interpolation

This function interpolates ArtMesh and deformer deformations curvilinearly rather than linearly.
For more information on extended interpolation, click here .

Notes:
Extended interpolation divides the keyforms of the parameters into multiple linear interpolations so that they appear to be interpolating curvilinearly between keyforms.
Therefore, moc3 can be exported in Cubism3 format to work with any version of Cubism 3 SDK.
Also, when extended interpolation is used extensively, the size of the moc3 file will be larger than when it is not used.

ArtPath

This function reproduces hand-drawn lines as a “dynamic mesh” in Cubism and handles them as a new object “ArtPath”.
For more information on ArtPath, please click here .

Notes:
ArtPath is not supported by Cubism 4 SDK.
In addition, information on this function is not written to any of the embedded data.

 

Form Animation

The ability to edit the model's ArtMesh or deformer directly on the Animator timeline, without going through parameters.
For more information on form animation, please click here .

Notes:
Form animation is not supported by Cubism 4 SDK.
In addition, information on this function is not written to any of the embedded data.

 

Sequentially numbered image track

This function allows you to batch place images exported as sequential numbers on a dedicated track.
For more information on sequentially numbered image tracks, click here .

Notes:
Sequentially numbered image tracks are not supported by Cubism 4 SDK.
In addition, information on this function is not written to any of the embedded data.

 

Onion skin

An editing aid that displays interpolation results for meshes and deformers.
For more information on onion skins, click here .

Notes:
Onion Skin is not compatible with Cubism 4 SDK.
In addition, information on this function is not written to any of the embedded data.
