Bunny from 'The First Descendant'
It requires GDC's costume mod and Hanmen's NextGen shaders.
These cards have their own body shape(Exbody) that is carefully tuned to match each costumes.
Please note that this will show a better shape, but it may not look good in other outfit.
Both cards have a 'Dainty Deformer' linked to their helmets.
This is a very simple and easy way to hide hair when wearing a helm, but sometimes it can cause a lot of problems. (when moving or switching the characters)
If this causes any problems, please remove the deformer from the accessory and manually turn the hair on and off.
Also, her eyes tend not to follow the camera well enough.
This is a chronic problem in HS2, and it gets worse as the character's eyeball becomes smaller.
There is a workaround to make the eyeballs bigger, but it is not a fundamental solution.
To solve this, Studio has a gaze control plugin, so please utilize that.
