Depth camera pictures don't look right

[XXLiu-HNU]

I encountered two issues while using the camera. The entire environment is shown in the image.

1. I set up two boxes at different locations in the environment, but the depth didn't seem to differ.

box_1 = scene.add_entity(
        gs.morphs.Box(
            lower=(1.0, 0, 0.02),
            upper=(2.0, 0.1, 0.1),
        ),
    )
    
    box_2 = scene.add_entity(
        gs.morphs.Box(
            lower=(0.5, 0.1, 0.02),
            upper=(1.0, 0.3, 0.1),
        ),
    )

2. There was no image of the other drone.

drone_target = scene.add_entity(
        morph=gs.morphs.Drone(
            file="urdf/drones/cf2x.urdf",
            pos=(0.5, 0, 0.02),
        ),
    )
    
    drone = scene.add_entity(
        morph=gs.morphs.Drone(
            file="urdf/drones/cf2x.urdf",
            pos=(0.0, 0, 0.02),
        ),
    )
