So I’ve been kind of working on this for about two days now and I can’t seem to get that rim to give off a glow that I’d like. Originally I’d like to have something of the sort like the first picture http://images4.alphacoders.com/287/287066.jpg that I googled. I feel like I’m almost there, but I’m having the most difficult time creating a glowing material in cycles that wouldn’t light up the whole planet (i.e. emission on rim). Goal is to have that glow without the need for post-processing. If anyone would like to toss in an idea I’m all eyes.
1.2: Node setup for the rim light. Original thought was that since I can separate the rim light by removing the transparency node I could mix in emission/blur, but it didn’t work out too well. Whole planet was enveloped in a very bright blue ball instead.
The mesh is just a couple of icospheres, one for the planet and one surrounding that for the atmosphere. The material for the planet is a dark grey diffuse and the sun lamp’s strength is 100 for my scene. The main things to play around with to get this shader working are the first gradient and the sun strength. A pic of my scene
