Update (ver.14)
1) The "Change Clothing" button has been split into "Change Real Clothing" and "Change Not Real Clothing" buttons, allowing you to specify what to change separately.
2) Change the default value of the "Use Shortcuts in Scene Load Dialog" toggle to on. This will display a list of var files in the scene load dialog. If there are a large number of var files and operation is slow, uncheck this.
3) Significant reduction in appearance loading time (depending on operating environment)
4) Improved stability of Sim clothes when loading appearance
5) Reduced cases where Clothing materials and colors are not applied correctly
6) Countermeasures for cases where some files cannot be read correctly
7) Countermeasures for cases where Scale is applied even when turned off
8) Change license from CC BY-NC to CC BY-SA
9) Other adjustments
Thanks to
