원인은 `UniversalToonBody.hlsl` 의 `InitializeStandardLitSurfaceDataUTS 메서드` 에서 `outSurfaceData` 이 초기화가 되지 않았다는 뜻입니다.

 

 

 

InitializeStandardLitSurfaceDataUTS 의 메서드에 초기화 로직을 추가합니다.

inline void InitializeStandardLitSurfaceDataUTS(float2 uv, out SurfaceData outSurfaceData)
{
    outSurfaceData.clearCoatMask = 0.0h;
    outSurfaceData.clearCoatSmoothness = 0.0h;

    ...
}

 

이후 제대로 나오는 것을 확인 할 수 있습니다.
