Quadrangolar mesh

Hello guys! I’ve a doubt about quadrangolar mesh in UE4. I looked for similar topics but what I found I believe is too old so I prefer ask to you (if I didn’t look weel I’m sorry).
I’ve a quad mesh (.obj) that I used in Blender but when I import it in UE4 (in fbx format) and I want to see wireframe this is triangular. So UE4 doesn’t read quad mesh or I miss something?

In game engines the meshes are all made of triangles. Internally with all 3D software meshes are made with triangles even if they display quads.
