That's really great and quite conveniently timed for me I've been working on my own sky rendering over the last week or so of evenings[1], to end up as a Godot plugin and perhaps a writeup. It started as deep dissatisfaction with the results I could achieve with what was available. I'm still on the fence about the distance to go for realism vs whatever I find aesthetically pleasing.

Can you tell I don't publish many youtube videos? Apparently "unlisted" didn't do what I wanted.
All good. It works now, and it looks great! I'd be interested in the plugin and write up. How can I get notified of updates?
