I just started playing around with Godot 4.0 beta12 and was surprised to see that lighting has had some big changes. Probably the fist I noticed was that the viewport lighting no longer matches the runtime lighting. I was wondering if there was a good tutorial somewhere which covered the new lighting system. Lighting is a pretty complex topic in 3D, and it's not always obvious how all the different options can help and how they're meant to be used.
