ply or any distinct type of 3D files with a PLY extension. Unity supports the following 3D file formats. Users can develop 3D models and import them into Unity, but what file types are endorsed? This article will glance at the 3D file formats Unity 2021 supports – inluding FBX files- and how to import these 3D models. Unity 3D is a 3D game engine that permits users to create 3D games in an arena. This article explains how to import files into Unity 3D directly, and through modeling software extensions. ARENA is a project led by Carnegie Mellon University.As connoisseurs of Augmented Reality, it is our dream to begin working in Unity to allow for interactive content in apps such as Over. Separated animation and model files do not work (Unity FBX convention is to separate mesh from animation files, so significant animation+mesh reprocessing may be required for proper animation export to GLTF.)Ĭopyright © 2020-2023, CONIX Research Center. All animations must be contained and combined within the same model for animation export to work. Animated models in Unity should be set to “Legacy” mode with compressed keyframes.

It is possible to export animated models from Unity.It is possible to export transparent materials.Real time lights should be recreated in ARENA. Unity real time lights do not appear to be exported.It is possible to bake approximate lightmaps directly onto diffuse textures to create “fake” shadows. Normal maps are supported however other more complex shaders are not supported.This reduces load time significantly and reduces the change of material application error in ARENA.

Textures should be also be combined to single atlased “large” compressed textures as opposed to multiple single texture in either PNG or JPG.

Meshes should be compressed by reducing floating point accuracy and decimating mesh polygon count.

In order to optimize load times, reduce file sizes and increase frame rates, all meshes with same material should be combined into single mesh.

A plugin like GLTF Exporter can be useful with the following guidance. There are some limitations and things to keep in mind when exporting from Unity. This site uses Just the Docs, a documentation theme for Jekyll.
