When @Dimava came up with the Live2D solution the first application came into mind was this one. However the engine MountBatten uses was TyranoScript instead of Unity which I assume it’s not plug-and-play.
Also MountBatten resumed development and is working on the maid scenes.
Well, I’ve checked Tyrano Live2D, it works mostly the same and I also can get the points
Buuuuut
Here I don’t have that “show vertices” button I had in unity so I’d have to implement drawing myself 
…
Not that hard now when ik what I’m looking for, just somewhat time consuming
Thanks for answering. I don’t know if it’s possible but I may have time to help you if you have any tasks to give. I don’t have any experience tho.
