Question How to change Camera Background Type in HDRP

I'm trying out the latest scene templates in Unity 2020.2.3f1

I was trying to set up a scene without a "realistic" sky. I don't want a horizon.

That used to be as simple as changing the Background Type on the Main Camera to None or Color.

In HDRP, that drop-down box does not give expected results. Are there other settings in other places that now need to also change to get the classic result, either None, or the Color selected in Background Color?

 

Same here, there is a horizon what ever I do! Any help with this?

 

You guys could use a hdri sky and just use a small plain colored texture as cubemap, that should give you a one color background without a horizon, I think.
