A long time ago I made this mod of Duna, before I decided to use mars as a template instead and make my Rald Planet. So, this adds an ocean* to duna, and O2 to its atmosphere. The atmospheric pressure is doubled, but the MW of the atmosphere is decreased a bit (to a MW representing 70% CO2, 15% O2, and 15% N2). Also, the ground near the shore is tinted green... sort of. The ocean is sort of a blue-green color, and the idea is that there is life in the ocean. * Well, its not really an ocean, its just a collection of lakes, channels, and seas, most of the planet is still dry. The idea is that its in the process of loosing its oceans, but they aren't gone yet. Hence, the name "Dying Duna", not "Dead Duna". To make the oceans, I applied a 750 m offset to the height to lower the terrain below 0 altitude, so I then increased the radius of the planet by 750 meters, so that it should be the same size as before. To keep ike's orbit period the same, I slightly lowered the gravity at the surface (to be equal to the gravity at 750m on stock Duna). I also deepened some valleys, so the height map is not quite identical, but in most places the terrain should be exactly the same as stock duna https://www.dropbox.com/s/p2hat7zj2024hxu/DyingDuna.zip?dl=0 ^ Note, the above images were taken when playing a 3x rescale (Sigma Dimensions mod) with vertical height only rescaled 1.5x. The uploaded version is "stock" size. Any yes, I know some areas right near the shore are red, I plan on fixing that. I figured I'd release this anyway in case someone is interested in it. As with my planet Rald, textures that look super green from orbit don't look so green from the ground. I intended for the shores to be green, but they seem to simply go from red to brown instead of from red to green. I may come back to this later. Also when scatterer updates, it will get a config for scatterer, and a nice greenish ocean... I'm thinking of colors like this (from the scatterer album) But this would be going too far:
