When I put a Live2D model in Unity 5.5 using SDK 2.1, I noticed that some body parts of my model is missing.
Take a look at attached screenshot, notice her missing left eye:
I also found this also happen to some other Live2D models, This one is even more sad:
Not all model are affected by this issue, although I wonder what causing this? I never had this problem when I'm working with Unity 4..
