3ds Max can import and export the text-based (ASCII) Wavefront format OBJ. An OBJ file contains geometry descriptions, while the associated MTL file format contains material descriptions.
The ASCII-based OBJ format makes it possible to exchange graphical data between many applications. Both polygons and freeform geometries such as curves are supported with this format. You can export 3ds Max files to this format.
Geometry imported from OBJ files appears in 3ds Max as editable mesh or editable poly objects. Import of associated materials and maps is supported.
The Map-Export dialog provides settings for exporting maps as part of material definitions along with exported OBJ files.
