What is an OBP file?
An .OBP file is a data file that serves multiple purposes depending on the software that created it. Most commonly, it is a Bryce Object File used by 3D software like Bryce (developed by DAZ Productions) or Cheetah3D. These files store 3D object presets and materials for use in rendering digital environments.
Alternatively, an .OBP file can be a 3D scanner project file created by the open-source OpenScan 3D scanner system. Finally, the .OBP extension is also used by the openBVE train simulator for add-on packages. In the case of openBVE, the file is actually a standard .ZIP archive with a changed extension.
How to open OBP files?
Because .OBP has multiple possible meanings, you must know the file's origin to open it correctly. If the file is a 3D object preset, you need Bryce or Cheetah3D. If it is a scanner project, you need the OpenScan software.
If the file is an openBVE add-on package, you can simply rename the file extension from .OBP to .ZIP. Once renamed, you can open and extract the contents using standard unzipping tools like 7-Zip or your operating system's built-in file explorer.
viewer.online/Inspect files with obp
Since an .OBP file can be a 3D model, a scanner project, or a compressed archive, you might not know which software to install. viewer.online/obp can analyze .OBP files to identify the exact format and creator software, inspect the file structure, extract readable text, and check whether an online preview is available.
Summary
Using viewer.online/obp is useful for identifying, inspecting, and understanding .OBP files without installing software or dealing with compatibility problems.
