You can also achieve the same affect with Baryonyx's Adjustable SkySphere mod which can also be used to change the background as easily as swapping objects in and out of a bag.

I made a couple of examples using Baryonyx's mod:

No thanks, learn what I've outlined in my previous comment and make it yourself.

I'm a professional 3d artist but I don't understand unity very well yet. What I'm looking for for my game is a controller that allows me to load the URL to the HDRI lighting files that I want to use, and be able to switch between them at the click of a button instead of having to load the URL in the game menus every time.
I would be more than happy to lend my skillset to a project like this if I could find someone who is capable of making it work. I sent you a friend request if you're interested.

Yes but nobody would understand how to use it.
Make a sphere and unwrap it so you can wrap HDRI images to the inside of it.
Add a runtime reflection probe in Unity, export as an assetbundle.

Is there any way that you can make something similar that switches HDRI lighting spheres instead of solid RGB colors?
I'm willing to create 3d models for a project like this if it can be done.

Used it in my Railroad Ink mod, if you're curious of potential use for it: https://steamproxy.com/sharedfiles/filedetails/?id=1517899401

onPlayerTurn(color) but it would be very jarring and annoying to do so.

jou! can you link it to player in turn somehow

You The Best CHRY!
