"if so is there a link to activate it in vr?" - not sure what you mean exactly here?

maybe lets just start with besides my computer is there another platform to download my art like icosa is it viverse now? when I'm in vr it is still trying to export it to sketchfab and i don't know how to change it

You can upload to Sketchfab or Viverse currently. Icosa upload will be back soon. (we disabled it temporarily. You can still upload to Icosa directly on the icosa.gallery website though)
