In a traditional 3D production pipeline, image production using 3D programs undergoes a process called rendering to visualize 3D data and this process is time-consuming and costly.By adopting a game engine for real-time rendering to check render images instantly, we can reduce the production time a lot.In this experiment conducted in this study, rendering process using game engines with the highest market share in various fields, Unity and Unreal Engine were compared and analyzed.Also this work aims to propose a method for adopting a game engine lighting and rendering to 3D production pipeline by using both engines.In this study, interior modeling was used to compare rendering in both Unity and Unreal engine.The analysis results indicate that Unity and Unreal Engine enable rendering in real time; consequently, the rendering cost is reduced.Moreover, the quality of the rendered image is almost similar to that produced by offline rendering images.The proposed technique involves reducing the render time and providing guidance for artists through access to a real-time rendering engine by comparing and analyzing the rendering of Unity and Unreal Engine through this experiment.
