XR Origin에 Camera가 있어서 Main Camera는 삭제

 

XR Origin에 AR Plane Manager 추가하고 Detection Mode를 Horizontal로 변경

 

DetectedPlane이라는 빈 오브젝트 추가하고 Mesh Renderer, Filter, Collider, AR Plane Mesh Visualizer[이거 추가하면 AR Plane 자동으로 추가] 추가

 

Material 추가, Rendering Mode - Transparent [반투명으로 보이게] , Color.A 값 166으로 수정

 

 

 

카메라 안 켜질 때 IL2CPP랑 ARM64 체크

M_Indicator의 Albedo에 드래그 앤 드롭

 

Quad를 만들어주고 이름을 Indicator로 변경, Materials에 M_Indicator 넣기
