Cubism 5.3 alpha New Features Digest

Precautions for Use

Purpose of alpha version

This alpha version is intended to evaluate the usability and performance of the new features and improvements planned for Cubism Editor 5.3.
Therefore, you will be able to try out new features before they are available. However, some functions may not yet be implemented, or the operation may be unstable and behave unexpectedly.

The UI is based on specifications currently under development and may change in the future.
In addition, there is a possibility that data such as model files (.cmo3) and animation files (.can3) that you have created may no longer be opened (incompatible) due to bugs or specification changes.

While it is possible to create works using the alpha version, we strongly recommend that you use it to “evaluate” the usability and performance of the new features.

Please ensure you fully understand the purpose of the alpha version before using it.

Setting information for alpha version of the Editor

If you are already using the full version of Cubism on your PC, Editor settings such as keyboard shortcuts will be inherited when you start Cubism 5.3 alpha.
At this time, the settings for the alpha version will be saved in a different location than the full version and will not be shared thereafter. This is to preserve the operating environment of the full version.

Note that due to this fact, setting items changed in Cubism 5.3 alpha will not be carried over to Cubism 5.3 beta and the official version.
Note: Setting items changed in 3.x and 4.x will be carried over to the 5.3 beta and the full version.

The settings files for Cubism 5.3 alpha are saved in the following folders.
Note that these settings files are not used in beta and later versions, so there is no problem with deleting them.

Windows	C:\Users\[USER_NAME]\AppData\Roaming\Live2D\Cubism5.3alpha_Editor C:\Users\[USER_NAME]\AppData\Roaming\Live2D\Cubism5.3alpha_Viewer
Mac	/Users/[USER_NAME]/Library/Live2D/Cubism5.3alpha_Editor /Users/[USER_NAME]/Library/Live2D/Cubism5.3alpha_Viewer

Note: Please be careful when handling these folders as they are hidden folders.
Note: If Cubism 5.3 alpha does not work properly, it may help to delete the above folders. Once the folders are deleted, if the settings files for the full version Editor (3.x /4.x) are already on your PC, they will be transferred over again.

English editor

Note that some wording newly added in Cubism 5.3 alpha may be of lower translation quality.

Note that it may take time to translate some of the manuals as well.
