Where I work, we have to use Maya as our level editor. For all the pain this causes, there’s a functionality that makes me go “arrrgh” whenever I come back to Unreal: snapping objects to stuff.
Being able to snap objects to vertices, edges, faces or the grid via a mouse-based shortcut regardless of the object’s location (alt+middle click in Maya’s case) makes level authoring so ridiculously faster that not being able to do so feels like going back to the stone age.
The various snap/align to floor functions that are already present are super useful, but they require that the actor is roughly in the right place.
Having a “teleport actor to” function would be really really nice.
