live2d define causes error in renpy8

[YuanlinLi]

it's okay in renpy7

image hiyori = Live2D("live2d/hiyori/hiyori.model3.json", zoom=None, top=0.0, base=0.6, height=0.9, alias={}, loop=True, fade=True, seamless=None, attribute_function=None, attribute_filter=None, update_function=None,aliases={"idle" : "m01"})

I'm sorry, but an uncaught exception occurred.

While running game code:
  File "game/script.rpy", line 33, in script
    image hiyori = Live2D("live2d/hiyori/hiyori.model3.json", zoom=None, top=0.0, base=0.6, height=0.9, alias={}, loop=True, fade=True, seamless=None, attribute_function=None, attribute_filter=None, update_function=None,aliases={"idle" : "m01"})

[renpytom]

The error message was bad, but the fundamental cause of this was a too-old Live2D dll.
