Convert a file to INN

To convert other file formats to the "Proprietary 3D Asset" file type, you need software like Lumion or a similar tool.


About INN files

An .inn file is a proprietary 3D asset generated by Lumion, a real-time architectural rendering software developed by Act-3D. When a user imports a 3D model from software like Autodesk 3ds Max, Lumion automatically converts the geometry into a set of internal library files, which includes the .inn file. This format stores specific mesh parameters or node configurations required for Lumion's real-time engine.

The main disadvantage of the .inn format is strict vendor lock-in. It is a closed, proprietary file type. You cannot open it in standard 3D modeling programs like Blender or Maya. Accessing the file natively requires an expensive commercial license. Furthermore, these files are not supported by web browsers or generic 3D viewers, making client collaboration difficult without rendering the scene first.

Users frequently need to convert .inn files to standard formats like FBX, OBJ, or DAE to recover the 3D mesh geometry and edit the model in other software. Converting to FBX retains UV maps and basic material assignments, while OBJ provides a universally compatible geometry structure without complex textures.

This file format is exceptionally difficult to convert. Standard online converters fail because the format is undocumented and locked by the developer. Usually, only the original Lumion software can properly read or export the 3D data. Our analysis tool inspects the file headers to extract raw embedded text. If our system detects a supported underlying or embedded format, viewing or partial conversion may still be possible.

Convert.Guru analyzes your INN file, detects the exact format, and lets you read the text inside.

Users also converted SIM, INDD, LNM, LME and LS11 files.

The INN Converter Story

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our INN converter.
