Transport Fever mesh

File type category:
Game file

Date updated: October 7, 2026

Transport Fever is a management simulation and railroad tycoon game developed by Urban Games for Microsoft Windows, macOS and Linux. Its model resources can use the .msh.blob filename extension.

The blob file stores binary mesh data for the game's 3D models and forms part of the model resources loaded by Transport Fever. It is a game resource rather than a general-purpose 3D model file, and is intended to be used by the game.

How to open blob file?

Open a Transport Fever blob file through the game on Windows, macOS or Linux. Place it in the appropriate game or mod resource location if it belongs to a mod, then let Transport Fever load it as part of that mod or resource.

The file is not intended to be opened independently in a text editor or general-purpose 3D model viewer.

How to convert blob file?

There is no general-purpose conversion option for a Transport Fever blob file. The file is a game-specific mesh resource and cannot normally be exported directly to common 3D model formats.

To create a different model format, work from the original 3D asset or source mesh and export it through the appropriate Transport Fever modding workflow.
