I’m trying to implement an effect where an orbiting planet up in the sky appears properly lit. So the side facing the sun is lit, but the side facing away is transparent. I’ve figure out how to make it be “dark”, but that’s not what a celestial body really does on the dark side. On the dark side, the atmosphere of the planet you are on is brighter and so you can’t actually see it. Like the way the moon looks when you see it during the day.
This is what I currently have:
But in reality, the dark part of that sphere should be ‘transparent’, while the side facing the sun is visible. When I use translucency, the whole thing becomes unlit and doesn’t pay attention to the sun. I’ve tried additive, but that just makes the whole thing unlit. What would work best is if I could use the brightness values as a transparency level. I’m using the standard sky sphere for the rest of the sky.
