Update:
1) Changed the standard save format of Hand Morph Manager to vap format. By changing the extension of the file name when saving to "json", it is possible to save in the previous format.
2) When saving as a vap file, you can load it as a Pose Preset with the standard function of VAM by adding "Preset_" to the beginning of the file name and saving it in "Custom / Atom / Person / Pose". In that case, please use Marge Load.
3) Hand Pose can be loaded directly from the VAM Pose file (vap / json).
4) Added a button to open the Pose folder. It is possible to display with "All Flattened" and "Add on Packages Flattened".
5) If there is only one Person in the Scene, you can directly load the Hand Pose from the Scene file (json).
