Saturn

I've wanted to try creating a scene in space lately, and I love Saturn. I spent today working on the textures and threw together a quick lighting set up and render. My aim is to have Saturn in the sky and the environment of the viewer will be from one of Saturn's moons. I'll be looking around for references so as I can find a cool lifeless environment to create.

I'm having an issue with getting Substance Designer to switch to 4K resolution for the rings (though I'm not sure if I'd actually need something this high), and one idea I had is to have a repeating texture a few times around the ring, but I'd need to figure out how to have a separate UV map for the light map resolution. If there isn't a way, that's cool, because from the looks at these images, 2k resolution seems to be just fine.

I'd also like to get the fresnel outline of the planet not show up when that part of the planet is in the dark. Is this possible?

Why do you need a light map for a planet? There's pretty much only direct lighting. Shadow from the planet should be much sharper.

@ZacD I was looking to get the shadows sharper, as you are suggesting, and everywhere I've found says to increase the light map resolution. After thinking about it, I understand the fault in my logic. Any idea how to increase shadow sharpness with the directional light?
