So the thing that wasn't clear to me was which modifier to apply before uploading. Applying shrinkwap didn't make any difference as far as I saw. Mirror seemed necessary, but with subdivision you lose the creases. Subdivision lvl 2 gave a too dense wireframe in sketchfab. Also very annoying I go some issues after uploading that werent there on my pc. In the end I only used subdivision 1 and uploaded my orb as an .obj file. How did other people do it.
