Notes for updating to Cubism 3.3 or later

[Last updated : 09/03/2019]

Cubism 3.3 Editor has been updated to improve warp deformer quality.
This change also applies to the output moc3 files and the Cubism SDK and Cubism Core used for loading.

Regarding the moc3 file version, until now there was only a single file version, but
with this change will allow different versions of data to exist simultaneously.
When I load a new file version of moc3 on an old Cubism Core, csmReviveMocInPlace returns NULL.
Please note that the model cannot be loaded even though the file and SDK are normal.

For more information on moc3 file versions, see “moc3 File Versions” in the CubismCoreAPI Reference.


The following SDK versions are compatible with Cubism Editor 3.3.

SDK Type SDK Version
Cubism SDK for Unity Cubism 3 SDK for Unity R10 or later
Cubism SDK for Native Cubism 3 SDK for Native beta 9 or later
Cubism SDK for Web Cubism 3 SDK for Web beta 4 or later

If you are using Cubism SDK for Unity, please also check “About Projects Generated by Unity2018.3”.


Q & A

Q: If I update Core, can I still read the previous version of moc3 files?

A: Yes, Core is compatible with all previous file versions.
It works even if the file version is a mixture of old and new.


Q: I would like to find out which version of Cubism Core is being applied.

A: During development, this can be checked by the return value of the csmGetVersion function.
For software that uses OWSDK, the Core version is output to the log when the framework is initialized.


Q: I want to check the version of the output file.

A: Currently no confirmation method is provided.


Q: Do I need the new Cubism Core to read the moc3 output from the new editor?

A: Only files with the new features applied will be required.
If the file is a conventional method, it can be read by conventional Cubism Core.


Q: How do I output moc3 in the conventional way to work with older SDKs?

A: In the Export Settings dialog, in the Export Version combo box,
if you select “SDK3.0 / Cubism3.0(3.2) compatible” for output
Conventional moc3 files can be exported.
