I confirm that apparently the top camera is orthographic (also in Pro). I created two cubes, one red and a slightly less large (in X,Y) green. I raised just a tiny bit the green cube and rendered with the  light coming from the top. As expected from an orthographic projection, I got a green square sorrounded by a tiny red border, of equal width on all sides.

This means that Vue can be used as a texture generation program: create the texture you want and apply it to the ground, put the sun right above and render appropriately!
