FBX vs OBJ
FBX may carry scene data such as rigs and animation; OBJ is commonly used for mesh geometry and may reference materials separately.
Which format should you choose?
Use FBX for supported scene features; use OBJ for straightforward mesh exchange. Test the destination app.
Good fit for FBX
3D production handoff
- Passing rigged characters and animation between compatible creation tools
Good fit for OBJ
Mesh exchange
- Moving a static mesh between 3D modeling applications
Basic information
| Field | FBX | OBJ |
|---|---|---|
| Extension | .fbx | .obj |
| MIME type | application/octet-stream | model/obj |
| Common uses | 3D production handoff | Mesh exchange |
| How to open | Open in an FBX-capable editor or viewer and inspect meshes, materials, textures, scale, rigs, and animation. | Open in an OBJ-capable viewer or 3D editor and check MTL and texture references. |
| Export or convert | When converting to glTF, verify materials, texture links, animation, units, and axis orientation. | When converting, inspect face orientation, materials, textures, units, and scale. |

OBJKey point 1
FBX can carry broader scene data depending on tool support.
More on the differencesKey point 2
OBJ focuses on geometry and may need companion MTL and texture files.

Check scale, axes, normals, UVs, materials, and animation in the receiving workflow.
- FBX feature support varies by exporter and importer.
- OBJ material and texture references may be stored separately.
Frequently asked questions
Does OBJ preserve animation?
OBJ is generally used for geometry exchange, not a full animated scene. Use a format supported by both tools for animation and test the transfer.
