The OFF file format is a general-purpose text file format used to represent 3D models and their associated geometry. The format, also known as Object File Format, compared to other 3D formats such as FBX, is very simple in its capabilities.
The main limitation is that it is only able to store the vertex and face information of the 3D model. Material information, textures, and face or vertex colors are not supported. Along with these limitations, the format is plain ASCII text, meaning large or complex 3D models will lead to very large OFF files being produced.
OFF files can be opened in most 3D modeling applications. Where integrated support may be lacking, there are usually third-party plugins and modules that can add support for OFF files.

When converting 3D model or mesh files using our OFF converter, we will attempt to convert color materials into a suitable format for use in the converted file.
The OBJ file format is a 3D graphics file format used to define complex 3D models, including geometry, materials, and textures. OBJ files are text files, making them human-readable and easy to modify by hand. The downside to this ease of readability is that the files can become rather large when dealing with large or complex 3D models.
As mentioned, the OBJ format stores not only 3D model geometry but also materials and textures. These materials are usually defined in a separate file with the MTL file extension and specify geometry rendering details such as diffuse and specular color, transparency, and much more.
The OBJ material file can also reference external texture files. These are usually JPEG or PNG files; however, these can be older formats, such as TGA. Where materials are used, the OBJ file will also contain material names preceding the geometry faces they should be applied to. If textures are referenced, the geometry will also contain texture coordinates (UV) for each vertex.
