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 glTF files as shipped: Upload, choosing a zip of the .gltf with its .bin and textures.
Import glTF into Sketchfab, step by step
- 1Check the fileOpen the .gltf in a text editor and look for a "uri" pointing at a .bin or image file. If there is one, keep those files in the same folder.
- 2Import into SketchfabUpload, choosing a zip of the .gltf with its .bin 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). glTF files are metres by convention, so they normally arrive at the right size.
- 4Check materials and animationglTF carries PBR materials; textures embedded as data URIs in our export and can carry animation. Look at the model under a neutral light before you build on it.
