The MTL file extension is associated with the Wavefront Advanced Visualizer 3D object application. This software is capable of viewing many different types of 3D object and raw texture files, including the MTL file format. It is an object material file format that stores specifications for the materials that are used to display a 3D object.
Content of an MTL File
An MTL file can contain specifications such as illumination models, transparency, refraction indexes, diffuse color values, reflectivity values, and other information that affects how a 3D object looks. It also contains type information and other meta data related to the 3D model itself. Examples of other types of data that an MTL file can contain are multiple texture information which stores information about 2D images that can be mapped onto a 3D object.
Usage of MTL Files
An MTL file is used in conjunction with an .OBJ file to define the materials of a 3D object in a scene. In order for a 3D object to be rendered properly all the materials must be defined and this is where an MTL becomes important. The .OBJ format will contain all the geometry and mesh components of a 3D model whereas the MTL file provides information on how these components should look when they are rendered using Wavefront or similar application. Other similar formats include .MTL, .MT2, and .LWO, each with their own specific purpose.

After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .MTL) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .MTL extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .MTL file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .MTL extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .MTL extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .MTL file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .MTL file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .MTL file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .MTL file) will be extended to the maximum.
It is also good to check
- if the .MTL file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
