Unity is a software developed by Unity Technologies for creating and operating real-time interactive 3D content (RT3D). Since its creation, the tool has been widely used in the gaming and film industries, but the architecture and industry have also adopted the virtual reality and augmented reality solution.

However, for the 3D content created in Unity to be easily usable in other 3D modeling software or in other game engines, it is important to have 3D interoperability. 3D interoperability is the ability of different 3D modeling software to communicate and share files.

Unity can read the following 3D formats (recommended source formats):

  • 3DS (.3ds)
  • Filmbox FBX (.fbx)
  • COLLADA (.dae)
  • DXF (.dxf)
  • Wavefront OBJ (.obj)

and the proprietary files of the following 3D modeling software:

  • Autodesk® 3ds Max® (.max)
  • Autodesk® Maya® (.mb or .ma)
  • Blender (.blend)
  • Modo (.lxo)
  • Cheetah3D (.jas)

In summary, using the .fbx file format in Unity is the best practice to ensure long-term 3D interoperability for your project.
