MTL is a material configuration file used by 3D modeling applications. MTL file stores information regarding texture patterns for given object, bitmap texture data, and texture positioning information.
MTL files are used by 3D modeling tools for storing material settings. MTL files store data in plain text format. However, manually editing the files is discouraged as it poses danger to the data data integrity and may affect the project development.
Below you will find an index of software programs that can be used to open MTL files divided into 3 categories according to system platform supported. MTL files can be encountered on all system platforms, including mobile, yet there is no guarantee each will properly support such files.
