Opening UNITY3D files

What is an UNITY3D file?

UNITY3D files are archives of different game data files and game asset files used in creating and playing 3D games. UNITY3D files are created by the Unity Technologies to run their own cross- platform game engine named "Unity". The Unity game engine is used to develop video games for both Webpages and for PC and mobile devices.

UNITY3D is a game file type that can be derived from a Unity Scene file. Unity Scene file usually contains all the data that made up the 3D environment of the game, including objects, buildings, people, lightings and dialogues. Unity scene file is the loose form of compressed .unity3d files.

UNITY3D files allow users to experience 3D gameplay using the latest Web browsers. The Unity Web Player plugin should be installed in the browser before playing.

The .asset files in UNITY3D file are usually in proprietary closed format. Opening, modification and extraction of the data inside are limited only to Unity Technologies and Unity game engine.

Try a universal file viewer

In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
