How do you turn off an objects interaction with others in the scene, but still show up in the render? I have several objects in a scene and my goal is to add a background image of some clouds and blue sky.  I downloaded a nice HDR and brought it in using add&gt;image&gt;background.  Looked nice but it did not show up in the render.  After some research I found I needed to import the image as a plane, which I did.
So I enlarged it and moved it to the back.  Its an outdoor scene so I am using the sun as a light source.  When I view it in material preview it looks fine.  When I go to rendered preview it acts like a large wall in the scene.  It casts a shadow and looks very dark, like a photo at night.
So is there a way to stop this plane from interacting with the scenes lighting but still be able to show the image in the final render?
I am using Blender 2.83
You don't need to put it as a plane, you can just import it as a background. You might have the background as alpha, if you do, turn it off.
