How to Open OBJ Files in Sketchfab
Sketchfab is the largest platform for publishing and embedding 3D models on the web, with its own viewer and store.
Short answer · Built in
Yes. Sketchfab opens OBJ files as shipped: Upload, choosing a zip of the .obj, .mtl and textures.
Import OBJ into Sketchfab, step by step
- 1Check the fileKeep the .mtl file and any texture images in the same folder as the .obj, with their original names; the OBJ refers to them by name.
- 2Import into SketchfabUpload, choosing a zip of the .obj, .mtl and textures.
- 3Check scale and orientationSketchfab works in any (the viewer frames the model) and is Y-up or Z-up (set in the 3D settings editor). OBJ files are unitless, so the size depends on what the exporter assumed.
- 4Check materials and animationOBJ carries basic materials in a separate .mtl file, and no animation. Look at the model under a neutral light before you build on it.
What comes through
| Shape | Yes, always. |
| Colours and materials | Yes: basic materials in a separate .mtl file. |
| Textures | OBJ doesn't store texture images. |
| Animation | No: OBJ has no animation. |
Things to watch for
- Uploading a lone .obj works, but materials will be missing.
- After uploading, open Edit 3D Settings to fix orientation, lighting and materials before publishing.
