Some VRM Model display anomalies

[DavidWeng916]

Hello @simplestargame, I applied your SimpleURPToonLitOutlineExample Shader to VRM's models and most of the model shows up fine. However, I don't know why this model is displaying strangely, its hair color should be blue but it turns pink and its face turns black, do you know what's going on?

When I commented out the 'Pass' in the following outline, it rendered correctly, so there may be an issue with the normals of your model.
