Hey Awa, looks like this is a question for the Model with Primatives exercise instead. We’ve had Sketchfab exercises in previous courses in the learning flow, so I assumed it would be familiar for most users. We’re working on a better upload system, but for now you’ll need to upload to Sketchfab directly.
cgcookie submit button gives no indication the model was uploaded – explains the identical models on Sketchfab as one keeps trying.
I’m really not sure how you could get a link from Sketchfab to put into the exercise without uploading it first. Were you getting an error from our site?
Sketchfab is another story – the model looks fine in Blender but is invisible in Sketchfab. Faintly visible in wireframe mode but the other modes are transparent.
If it’s invisible, then it must have to do with transparency. Try turning off the Opacity option in the Sketchfab material settings.
