I... didn't expect it to be that easy. Thank you so much!

So, I've seen videos and screenshots of transparent battlegrounds, so that you can see through the battle to the overworld. I think it's a lot more aesthetically pleasing, but I can't figure out how to do it. I tried a few different themes and that doesn't seem to do the trick, so... I'd appreciate any help I could get with this. Thanks for the time spent reading this, and I'm sorry if this isn't the right place to ask...
