Isometric 2d support

Hello, We want to create a 2d isometric game using pixel-art.

I have a few questions about UE’s support for this kind of game.

  1. Is isometric ordering supported ? for any sized objects ?
    for example, in my current setup I have a player and a bridge, when the player is under the bridge it shows like this:

as it should.
But when I move the player a bit he should be in front of the bridge but he’s not:

  1. Do I have to use tilesets and tilemaps ? I’ve seen that there is support for an isometric style tilemap, but we do not want to use a tilemap at all but to use predrawn maps and sprites.
    Is this possible in UE?
