I did switch on a few "environment" settings in Godot, like a subtle glow and soft focus, but nothing drastic.
Having said that, I do feel like I have more control over the lighting and shadows in Godot.
One thing has changed game-wise when switching from jMonkey to Godot. I've done away with the "Stockpile" (pile of crates containing your colonist's stuff) into a small warehouse. Later will come medium and large warehouses and maybe other storage methods. So now they actually go into the warehouse, pick stuff up and take it to where it needs to be.
