Earlier quoted context omitted.
What's missing? It's got rotating (MMB), panning (Shift + MMB), zoom (scrollwheel) and focus on object (F).
Zoom is limited. It's not infinite zoom. How do I move through the level in Z direction? I saw a video mention WASD keys but it didn't work for me. In unreal you can fly through the level using mouse and keyboard. WASD is cardinal direction and mouse is camera rotation. In godot mouse wheel zooms the camera, but I couldn't find a way to 'move' the camera in Z.
Afaiu the reason for two different camera control schemes in DCCs and game engines is that they’re suited to different workflows. On the one hand, object-centric orbit-style controls are great for, eg, modeling, whereas free-fly WASD / mouselook controls are great for level blockout, in-scene camera positioning, etc.
By default you have to hold the right mouse down to enable free-fly controls in Unreal.
Sorry you might know all this. Just if you are expecting one camera control scheme and getting another I know it can be frustrating.
