Thank you very much for sharing!
It was used to test cloning blend shapes in Hana_Tool.
This works perfectly for vroid BETA converted to Vroid Studio 1.0, however models made with Vroid Studio 1.0 do not appear to have the "look" up / down / directional functionality.
Vroid Studio v1+ is fixed, but you have to toggle off the delete meshes option when exporting to work with unity package Hana_Tool v3.
