Convert OBZ to OBJ

Understanding the OBZ and OBJ file formats

OBZ files are compressed scene files used by OpenBVE, a free train simulator. These files typically contain 3D object data, textures, and other resources, compressed using ZIP to reduce file size. OBJ files, on the other hand, are a widely supported 3D geometry format developed by Wavefront Technologies. The OBJ format is used in many 3D modeling and rendering applications, storing information about 3D object geometry, such as vertices, faces, and texture coordinates.

Why convert OBZ to OBJ?

Converting OBZ to OBJ allows you to use 3D models originally created for OpenBVE in a wide range of 3D modeling software, game engines, or rendering tools that support the OBJ format. This enhances compatibility and enables further editing or visualization.

How to convert OBZ to OBJ

Since OBZ files are essentially ZIP archives containing OpenBVE .B3D or .CSV object files, the conversion process involves two main steps:

1. Extract the OBZ file: Rename the .obz file extension to .zip and use any standard archive tool (such as 7-Zip or WinRAR) to extract its contents.
2. Convert the extracted B3D/CSV to OBJ: Use a specialized converter like BVE2OBJ or BVE Content Converter to convert the extracted .b3d or .csv file to .obj format.

Recommended software for OBZ to OBJ conversion

• 7-Zip or WinRAR – for extracting OBZ files.
• BVE2OBJ – a dedicated tool for converting BVE (B3D/CSV) files to OBJ format.
• BVE Content Converter – another utility supporting BVE object conversions.

After extraction and conversion, you can open the resulting OBJ file in 3D modeling software such as Blender or Autodesk Maya.

Step-by-step conversion process

1. Rename yourfile.obz to yourfile.zip.
2. Extract the ZIP archive using 7-Zip (Right-click → 7-Zip → Extract Here).
3. Locate the .b3d or .csv file inside the extracted folder.
4. Open BVE2OBJ and select the extracted file.
5. Follow the tool's instructions to export as OBJ.
6. Import the resulting OBJ file into your preferred 3D software.

Tips and considerations

• Textures may need to be manually reassigned in your 3D software after conversion.
• Some complex BVE objects may not convert perfectly; check the result and adjust as needed.
