I’ve gone and added clouds to the remake.<\/p>\n

After some searching, I came across a free Unity Asset store add-on called Simple Dynamic Clouds<\/a> by Butterfly World.\u00a0 It’s a very simple dynamic cloud effect that incorporates moving UV coordinates to simulate fractal Brownian\u00a0motion (FBM) using some specialized texture maps.\u00a0 However, it was too simple to use as-is as it generated only the color (albedo).\u00a0 So… I went into the code and added support for bumps (normals) and specular lighting.\u00a0 That made it look much better.<\/p>\n

To add the clouds to the game, I created a thin shell around each planet and applied the new clouds material and shader to it.\u00a0 The atmospheric density of each planet controls how thick the cloud layer appears.\u00a0 Also, if the planet is a molten planet, the clouds will appear dark instead of white and fluffy.<\/p>\n

Here are some screenshots!\u00a0 All of this is included in the latest game download.\u00a0 Note: The clouds animate very slowly – you’ll see different patterns form up and dissipate.<\/p>\n<\/div>
