Want to make a first person camera from scratch, no mesh

Hey! Im looking to create a first person camera with movement, but without the mesh/skeleton.

Im new to unreal engine / game dev but hoping I could get some help!
Im starting from a blank project and the first thing I want to learn how to do is setup player cameras.
I want a player camera that has no mesh (meaning, i want a first person in my game but i dont necessarily need a character.)

So heres what i attempted:

  1. I created a blueprint with the class PlayerController. For this reference I called it BPPlayer

  2. I added a component of the Camera, springarm , capsule(collision), arrow

  3. Im attaching an image of the hierarchy, I think its correct?
    image

  4. and then this is my viewport:

it… kinda loooks right to me being a beginner? :smiley:

If this is correct, which if its not please let me know, how would I go about adding the blueprints to make this playable/add input. Thanks so much!

as a bonus I would LOVE if you can not only explain how to accomplish this but why it works. I want to really understand! Thanks so much.
