OBJ File Format

Wavefront OBJ Model category

OBJ is the veteran plain-text 3D format from Wavefront: vertices, faces and texture coordinates in a human-readable file that almost every 3D package imports.

Typical use: OBJ opens in Blender, Maya, 3ds Max, SketchUp and countless model viewers — the safest interchange format for meshes.

About the OBJ format

OBJ (Wavefront, 1990s) is the veteran of 3D model exchange: a text file of vertices, UV coordinates and faces, optionally paired with an MTL material file and texture images. It predates every modern pipeline yet still opens everywhere, which keeps it as the default export of modeling tutorials, asset stores and scan software.

It is static by design — no animation, no rigging, no scene hierarchy beyond groups — and MTL's habit of referencing textures by relative path means a lonely .obj file often shows up untextured. For static meshes with appearance, it remains a dependable common ground.

Strengths

✓ Opens in every 3D application, old and new
✓ Text-readable and easy to generate programmatically
✓ Carries UVs and materials via MTL

Limitations

✗ No animation, rigging or hierarchy
✗ Texture references break when files travel alone
✗ Text format is bulky for dense meshes

Structure: Mesh + UVs (+ groups)
Materials: Via separate MTL file
Compatibility: Universal exchange veteran
Best for: Static model exchange
