At the moment I work on a sci-fi short film and for this I created a planet in Blender Cycles. I'm almost finished and I'm pretty satisfied with the result. The only thing left to do is the blurry atmosphere of the planet. I've watched several tutorials how to create an atmosphere but it still has sharp edges. Also I can't create it with the compositing node because I have moving objects infront of the planet that shouldn't have blurry edges or glow. Now my question: Is there a possibility to achieve the "blurry edge" effect (see images) with a material node?
Thanks for your answers!
