The Unity exporter lets you publish 3D models straight from Unity to Sketchfab. It uses the glTF format and supports model objects and PBR materials, as well as solid and skinning animations.
You will be redirected to the model page. When processing is complete, you can view your model on Sketchfab, adjust rendering settings, and save the default view.
