I cannot turn the lights out...

I want all ambient light gone. I recently upgraded my 2018.4 project to 2019.4 and then imported HDRP, and began going through steps to configure the materials/shader replacements. (working) However, now that I’m on the new graphics system, I want ALL lights off, and then just add specific lights as I go. removed all lights from a test scene. I found points that referenced ambient light, I believe for the sky, and could only select gradient, so I set all the colors to black. I found a couple other odd areas for that seemed potentially related, but nothing has removed the ambient light from the scene.

Can someone tell me where to go/what to configure to remove ambient light? - Thanks.

Hi,

ambient light is control by the Sky. You can configure the sky to use with Visual environment component of the HDRP volume settings system.
https://docs.unity3d.com/Packages/com.unity.render-pipelines.high-definition@9.0/manual/Volumes.html

Follow the step in the documentation here: Environment lighting | High Definition RP | 9.0.0-preview.71

And you can then assign your volume profile to static sky, so if you select none and bake, you will get black sky contribution for lightprobe / lightmap.
