Format guide
OBJ
Wavefront Object
OBJ is Wavefront's text-based 3D mesh format from 1990, the most-used asset interchange in computer graphics for decades. Plain text: "v" lines for vertices, "f" for faces, "vn" for normals, "vt" for texture coordinates. Optional companion .mtl file describes materials. Universal compatibility across 3D software but lacks newer features like PBR materials, animations, and skeletons.
