Beginners import a Unity Assets 3D model by opening their project, dragging the model file (e.g., FBX, OBJ) into the Assets folder (or via “Assets > Import New Asset”), adjusting settings (like scale or materials) in the Inspector window, then dragging the model from Assets to the Scene or Hierarchy panel.
The Assets folder stores all project content—tweak the “Scale Factor” to fix size issues, and add texture files here too so materials load correctly.
If textures don’t appear, go to the model’s import settings under “Materials” and select “Use External Materials”—this helps Unity link textures to the model automatically.
