Presentation with transparance backgrond

Hi Bartv,
Please tell me how to make (with a free sketchfab) a presentation with transparance backgrond like the car in sketchfab home page.
Thanks,
Guus Zeillemaker

You can use the transparent=1 embed parameter, but it’s usually not recommended because we cannot perform anti-aliasing on the model edges.
