Format Information

Source Format

FBX.fbx

FBX (Filmbox Scene)

FBX is Autodesk's scene format, written by Maya, 3ds Max and MotionBuilder. It is a compact container for a whole DCC scene, which is why it is the usual hand-off format when a model comes back from a modelling or animation package.

What it carries: Meshes, UVs, vertex colours, materials with embedded texture maps, a bone hierarchy, skinning, and keyframe animation clips. Blend shapes and Autodesk-specific property types are not read by this converter.

Target Format

OBJ.obj

OBJ (Wavefront)

The Wavefront OBJ format is a plain-text mesh description that has been the default interchange format for computer graphics since the 1990s. Geometry lives in the .obj file; colour and texture references live in a companion .mtl file.

What it carries: Vertex positions, normals, texture coordinates and polygon faces, plus what MTL can express: a diffuse colour, opacity, shininess and a single diffuse texture map. There are no PBR metal/roughness values, no normal maps, no vertex colours and no animation.

About this conversion

A DCC scene downgraded to the 1990s mesh format. The FBX geometry, UVs and node structure are written to .obj, and the material is reduced to what an .mtl can express.

Why convert FBX to OBJ

  • Open an FBX asset in a tool that only reads OBJ — older CAD packages, sculpting tools and slicers.
  • Publish a static, material-light version of a scene for the web with a hand-rolled OBJ loader.
  • Flatten a complex FBX scene into a single, portable mesh file.

What happens during the conversion

Geometry

Meshes, UVs and normals are written through and node transforms are baked into the vertex positions, since OBJ has no scene graph. Faces are triangulated, so n-gons become triangles, and every mesh in the scene is included — including ones hidden in the FBX, because OBJ cannot record a hidden state.

Materials and textures

Each material becomes an .mtl entry with a diffuse colour and, where the FBX material has one, a flattened base-colour map. Metallic, roughness, normal, occlusion and emissive maps have no MTL equivalent and are dropped.

Animation

FBX can carry keyframe animation, skinning and morph targets; OBJ cannot store any of them. The result is a single static pose of the scene as it stood.

Common use cases

  • Compatibility with legacy software that has never heard of FBX.
  • Producing a static mesh for shape review without shader setup.
  • Flattening a DCC scene into a single portable mesh file.

Limitations of this conversion

  • PBR maps beyond base colour are lost, and the result will look flatter in a PBR renderer.
  • Vertex colours are not written, and there is no place for animation, skinning or morph targets in OBJ.
  • Every mesh in the scene is written, hidden or not, because OBJ has no way to mark an object as hidden. Export to GLB or glTF if you need that distinction.

How to convert FBX to OBJ

Three steps in the browser. Nothing is uploaded to a server, so an unwieldy file is limited only by your own device's memory.

1
STEP 1

Upload your .fbx

A single file is enough since FBX embeds its own textures.

2
STEP 2

Convert to OBJ

Geometry, UVs and normals are written, with materials reduced to .mtl entries.

3
STEP 3

Unpack the ZIP before opening the result

A materialised model is .obj + .mtl + PNGs in one folder.
