Hey, I wanted to ask, how I can import 3D models, I downloaded from Sketchfab, to UE4. I am a complete Beginner and just wanted to play around a bit, but it seems that the models are saved as wrong document types or something? What do I do with the ZIP-thingy I get, when i click download? I unpacked it, but nothing inside is the right asset to import. What do I do wrong? What do I have to do, to do it right?
