I am working on a simple space combat game and am trying to use two viewports to set up an X-Wing style front and back radar display. I am trying to set the camera to follow a Position3D node that is attached to the player craft (called "Striker"). However, when I used the code
onready var front_radar_position : Node = get_node("/root/Main/Striker/radarFrontPosition")
onready var front_radar : Node = get_node("/root/Main/HUD/ViewportContainer/Viewport/radarFront")
func _process(delta):
front_radar.global_transform.orgin = front_radar_position.global_transform.origin
I get an "Invalid set Index 'origin' (on base: 'Transform' with value of type 'Vector3' error. It also doesn't matter if I place the code in the Main scene and reference the children from that script. I still receive the same error.

Any help you could give would be greatly appreciated. Thank you!
