Convert Irrlicht 3D scenes (IRR) online for free
The converter easily converts your IRR 3D scenes to various formats - free and online. No Irrlicht Engine or or other 3D software needed.
To convert other file formats to the "3D Scene Data" file type, you need software like Irrlicht Engine or a similar tool.
The .IRR file format is primarily an XML-based scene file utilized by the Irrlicht Engine, a fast, open-source 3D graphics engine used in game development. These files do not store 3D geometry natively. Instead, they define a 3D environment by recording the placement, scale, and rotation of external meshes, cameras, lights, and textures. A secondary, highly specialized use for the .IRR extension is the Brewer Lamp File, managed by Brewer Data Management Software to store scientific calibration data for spectrophotometers.
The main disadvantage of an .IRR file is its absolute dependency on external assets. Because it only stores reference paths to OBJ, B3D, or MS3D files, sharing an .IRR file without its accompanying texture and mesh folder makes the file completely useless to the recipient. Additionally, mainstream 3D modeling applications like Blender or Autodesk Maya cannot import .IRR scene files natively without custom plugins.
Users typically want to convert these scenes into universally supported exchange formats like FBX, GLTF, or DAE. However, standard online converters universally fail to process .IRR files because they cannot parse the specific engine XML schema or access the missing local mesh files referenced within the code.
Just drag and drop your .IRR file into convert.guru to identify the format, view its contents, and convert it when possible. Because the Irrlicht scene format relies on standard XML, our tool can inspect the file, reveal the exact file paths of missing assets you need to rebuild the scene, and help you salvage readable data from otherwise inaccessible environments.

Users also converted PKR and ROI files.
If you want to convert IRR file to PKR or ROI, you can use Irrlicht Engine or similar software from the "3D Scene Storage" category. In the File menu, look for Save As… or Export….
To convert files to IRR, try Irrlicht Engine or another comparable tool in the "3D Scene Storage" category.
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 IRR converter.
