Whoops, sorry, for the late reply but if you mean by importing it into blender you can do it by clicking file>import>fbx then you look for the "hello kitty sweater" file and it should show as a fbx then you open it in your project. Or an easier way is to use cats-Plugin to import fbx's. here's a video how to install it. I HOPED THIS HELP!!<33

I'm new to all this, can someone explain how to import it and turn it into an actual object??
