I don't know much about Godot 3d, but is there any chance of getting better lighting effects in the game? Something like ambient occlusion to lessen the harshness of the dark shadows and brighten up the night scenes would be great.
The short answer is ‘no’. There are three renderers in Godot. You can think of them as ‘fast’, ‘normal’, and ‘high quality’. Fast is the most compatible, and in theory can even be run in a web browser, though I’ve not been able to get that to work. I’m using ‘normal’, which doesn’t support a lot of the higher quality rendering options yet. I used the HQ one for my last game and people complained about visual problems on embedded hardware.
I am planning to brighten up the night scenes a bit by adding some moonlight.
