I experimented with the rotation, scale and location of my cone, in fact when dont apply the transforms (Ctrl + A), Unity don’t actualizes the modifications, but in the previous lecture I changed the rotation of my cube and this appeared exactly with the same rotation in Unity, I mean, I did not have to actualize the rotation in blender for that Unity could show the new rotation. 
Something interesting happened when I put a second object (Cylinder), Unity changed the position and rotation of this two objects, but I dont modifyied anything 
Also I noted that this time Unity recognized the materials added to the objects, unlike the previous lecture, where we have to removed the materials and re-import those
