I installed the importer for Sketchfab-to-Unreal-4 and the asset browser inside Unreal works fine and I can login and it shows all models with preview thumbnail etc.
But unfortunately it doesnt find my own models in the Unreal asset browser. The content browser on the Sketchfab website finds my models instantly with the right search words.
The same problem appears with the Sketchfab-to-Unity importer and the content browser inside Unity.
Did I do something wrong ?
