Abstract

There have been many studies to improve the efficiency of the CG production process, but it was not easy to overcome the problem that it was difficult to check the result in the middle of work and it took a lot of time for rendering. However, as the possibility of using Unreal Live Link, which can check the result in real-time, is increasing, expectations for improving the efficiency of the production process are rising. This study analyzed the efficiency of the 3D animation production process using Unreal Live Link. To this end, modeling, rigging, animation, and layout work were done in Maya, and the final output image sequence was rendered in Unreal Engine through Unreal Live Link. And the difference between this production process and the existing production process in which the final output image sequence is rendered in the 3D software itself was compared and analyzed. As a result of the analysis, unlike the traditional 3D animation production process, it was possible to check the final work result in real-time by proceeding with the work through a high-quality viewport screen, and it was found that the efficiency of work was maximized by deriving the final result through real-time screen capture. Recently, the use of game engines in the 3D animation and film industry is gradually increasing, and the efficiency of work is expected to be maximized if Unreal Live Link is used.

그동안 CG제작공정의 효율성을 향상시키기 위한 많은 연구가 있었지만, 작업 중간에 결과물의 확인이 어렵고 렌더링 타임에 많은 시간이 소요된다는 문제점을 극복하기는 쉽지 않았다. 그러나 최근 실시간으로 결과물의 확인이 가능한 언리얼 라이브 링크의 활용 가능성이 커지면서 제작공정의 효율성 향상에 대한 기대감이 높아지고 있다. 이에 이 연구에서는 언리얼 라이브 링크를 이용한 3D 애니메이션 제작공정의 효율성을 분석하였다. 이를 위해 마야로 모델링, 리깅, 애니메이션, 레이아웃 작업을 하고 언리얼 라이브 링크를 통해 언리얼 엔진에서 최종 아웃풋 이미지 시퀀스를 도출하는 방식으로 3D 애니메이션을 제작하였다. 그리고 3D 소프트웨어 자체에서 최종 아웃풋 이미지 시퀀스를 을 도출하는 기존의 제작공정과 본 제작공정의 차이점을 비교 분석하였다. 분석 결과 전통적인 3D 애니메이션의 제작공정과 달리 높은 퀄리티의 최종결과물을 보여주는 뷰포트 화면을 통해 작업을 진행함으로써 실시간으로 최종 작업 결과물을 확인하는 것이 가능하였으며, 실시간 화면 캡쳐를 통해 최종결과물을 도출함으로써 작업의 효율성이 극대화되는 것을 알 수 있었다. 최근 3D 애니메이션과 영화 산업현장에서 게임 엔진을 활용하는 사례가 점차 늘고 있는데, 언리얼 라이브 링크를 활용할 경우 작업의 효율성이 매우 극대화될 것으로 예상된다.
