A conversion of 3D graphics from Blender to Unreal Engine

Abstract

This paper describes the conversion possibilities between Blender and Unreal Engine. Although it may seem at first sight to be a simple issue, the opposite is true. Unlike 2D graphics, where a simple image is transferred from one graphics program to another, the problem is much more complex in 3D graphics. We want to transfer only the simple geometry of 3D objects very rarely. Blender is a tool for the entire 3D graphics pipeline - offers several types of representations, assigning materials and textures to objects, creating simple and more complex animations, various physical simulations, including collision detection (particle systems, fabric objects, flexible objects, liquids), etc. Unreal Engine is a state-of-the-art real-time engine and editor that features photorealistic rendering, dynamic physics and effects, lifelike animation, robust data translation, and much more. Main task of this article is to summarize the results of research aimed at finding out what can be converted between these programs and in what graphic formats. © 2021, The Author(s), under exclusive license to Springer Nature Switzerland AG.
