File extension mtl is mainly known to be used for Wavefront format.
Wavefront Technologies was a computer graphics company that developed and sold animation software used in Hollywood motion pictures and other industries. It was founded in 1984, in Santa Barbara, California, by Bill Kovacs, Larry Barels, Mark Sylvester.
They started the company to produce computer graphics for movies and television commercials, and to market their own software, as there were no off-the-shelf computer animation tools available at the time. In 1995, Wavefront Technologies was purchased by Silicon Graphics and merged with Alias Research to form Alias / Wavefront. It is now is owned by Autodesk.
Material library files contain one or more material definitions, each of which includes the color, texture, and reflection map of individual materials. These are applied to the surfaces and vertices of objects. Material files are stored in ASCII format and have the .mtl file extension.
The mtl file differs from other Alias / Wavefront property files, such as light and atmosphere files, in that it can contain more than one material definition (other files contain the definition of only one item).
Use Adobe Photoshop, or other tools to open .mtl material data files.
Use compatible tools to export .mtl to other formats.

Transport Fever is a railroad and transport management simulation developed by Urban Games for Windows and macOS. The game uses .mtl files as part of its 3D model resources.
An .mtl file contains material settings for a model, including information used to determine how its surfaces are rendered. It works with the model and texture resources that make up vehicles, buildings, and other game objects.
This is a game-specific material format used by Transport Fever and its mod resources rather than a general-purpose 3D interchange format.
Transport Fever loads .mtl files automatically when they are referenced by the game's model resources or installed mods. The file is not normally opened separately through the game's user interface.
Because Transport Fever material files are text-based resource files, a plain-text editor can be used to inspect or edit one on Windows or macOS. Changes should be made only when the file's structure and the related model resources are understood.
There is no general-purpose conversion that turns a Transport Fever .mtl file into another material format while preserving its game-specific settings. The file is intended for use by Transport Fever.
To use a material in another game or 3D application, the material normally has to be recreated using that program's material system, with the associated textures assigned again.
