Here is a Terraformed Mars. This terraformed Mars is a bit different then other peoples results, as I spent time looking at topography maps, and region maps of Mars, and planned out what biomes would actually have water. If we terraformed Mars from it's northern pole, we wouldn't have oceans or lakes on the bottom half of the planet, as it would be a desert, and water would have long dropped from clouds going over terrain before ever reaching the areas, and what little does fall isn't enough to accumulate anywhere before evaporating.
I tried to do dust clouds and weather clouds, but I am not happy with them. I may export a spherical cloud map to composite in with more natural shapes. Though I do want to make some clouds that resemble a dead Mars too.
Big thanks to Stormlord for the Maps. I have upscaled all maps used here to 32k via AI. The texture map is extensively altered in Photoshop using isolation and painting to fix other bad areas of the texture. I also did a delit version too but not as satisfied with that result.
PS Ridiculous I can render the planet and maps in 4 minutes, but with clouds, it takes 18 hours. Come on. >.< Why can't scalars be warped without hitting the renderer like a ton of bricks?
