Loading up Experimental version the buildings have taken a greenish hue. It looks like it's reflecting off of a building that I painted green, but it's more than that. The green "reflection" appears on any building I have no matter how far away it is from painted ones.
It's actually kind of cool looking, but didn't see anyone else mention this, thought I'd pass it along in case it can be of any help to you guys.
I love Satisfactory, thanks for all this.
