Unity Planet Shader + Live Demo
OPEN FOR FULL DESCRIPTION:
Use the demo live here (you need a WebGL compatible browser) -- http://www.lidia-martinez.com/materia...
Here is what this demo uses:
The planet shader contains a simple fresnel shader with more effect on the illuminated part of the planet, plus a little ambient light. Also uses a flowmap for the clouds I created with Flow Map Creator to change the clouds and offset both textures around.
A screen effect shader with a bloom shader I made up out of 4 passes (A high pass filter + vertical gaussian blur + horizontal gaussian blur + composition of the last three)
