MTL (OBJ Material File)

An MTL (material) file is most commonly associated with the 3D model format OBJ and is used by the OBJ file format as a means to store material information related to the OBJ model. This material information may also include textures, which are typically stored in separate image files.

The information is stored within the MTL file as plain text, making it easy to read and modify by hand. An MTL file does not have much use without the accompanying OBJ file; however, it can be used with our range of MTL converters to convert the materials into other 3D formats that also support materials such as FBX.
