How can you use a Flat 2D Background in place of a Skybox?

I’m a new Godot Engine user and I wanted to use it to try and make a retro 1990s style 3D game. One quirk I noticed in some early 3D games is that they would use a scrolling 2D images for backgrounds rather than a sky-box. This made background scenery appear flat with little to no 3-dimensional depth.

Example:
Scrolls horizontallyenter image description here

Scrolls verticallyenter image description here

little or no scrolling when camera is translatedenter image description here
This as an effect I would like to achieve in Godot, but I’m having some trouble with it.

I tried out the “WorldEnvironment” Node with a panoramic sky texture, but that looked too 3D.

Adjusting the “Sky Custom FOV” parameter made it flatter, but it was too zoomed in.

So I thought I’d come here to ask for help. What’s another approach I could take to create a flat looking background for a 3D game made in Godot?
