  • It saves asset properties and material definitions.
  • It is tuned for performance in specific 3D applications.
  • It is not commonly supported outside the native environment.

    How to open INN files

    You need a suitable software like Lumion to open an INN file.

If you cannot open your INN file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a INN file directly in the browser:.
