[Regarding macOS Tahoe](Updated September 18, 2025)
We cannot guarantee the compatibility of the current releases of Live2D Cubism Editor and Cubism SDK with macOS Tahoe.
We advise against upgrading your macOS at this time as it may cause Live2D products not to function correctly.
Upgrading macOS can also cause you to lose your Cubism Editor license file.
Please make sure to deactivate your Cubism Editor license before upgrading the macOS.

email form.Blend Shape Weights Duplicate Parameter Values Error
In Cubism Editor 5.0.00, when setting blend shape weights, if the values are within 0.1 of eachother, it gives the error:
There are duplicate parameter values.
And doesn't let me accept the changes.

Even just clicking on the "edit graph" button on the Step presets gives this error. Makes it impossible to do any type of custom "stepped" blend.
