Teralis - City Planet

The City Planet.



[h1]v0.3:[/h1] Major Visual Overhaul
[h1]v0.2:[/h1] Now with oceans!
[h1]v0.1.2:[/h1] Ores are now random
[h1]v0.1.1:[/h1] Now with custom ambient sounds




Teralis is the first ecumenopolis in space engineers. A planet covered entirely by a city.

All the buildings are built out of voxels just like a normal planet, only arranged to look like buildings.

Took me a long time to get this far, but there is still a long way to go.
This version is the first somewhat playable prototype version. I didn't want to keep this all secluded and since there is still a long way to go I thought I might as well publish an early testing version to the workshop.
Btw this is my first mod.

Since the planet is just voxels (no grass or trees), it should actually be fairly lightweight on your performance. So far all six sides of the planet are basically the same and not seamless, but you probably won't even notice it unless you're specifically looking for the seams. There are ores on the planet in the deepest crevices between the buildings.

Fun fact: the heightmap is a whopping 1.6 billion pixels, compared to the default 25 million.

Have fun messing around with it!


[h2]Stats:[/h2]
-Highly! Recommended size: 19 km
-Gravity: 0.9 g
-Atmosphere: 1 atm (breathable)
-Ores: All
-Buildings: ~800.000

[h2]How to Use:[/h2]
-Subscribe on this page
-During loading/ creating a new world, go to options->mods
-Add this mod to the list of active mods
-Ingame: shift+f10, select planets, select this one, spawn it in
(might freeze your game for a while)
-If shift+f10 doesn't work, alt+f10->tick creative tools

[h2]Important:[/h2]
In order for it to look good, follow these steps
-Spawn it in with a size of 19 km and not a meter more
-In your graphics settings, set shaders to high (glowing lights, gpu heavy)
-Set voxel quality to atleast high (extreme is better, but eats ram and gpus for breakfast)

[h2]Technical Details:[/h2]
-File Size: 255 mb (50 mb audio, 140 mb textures, 60 mb heightmap)
-Heightmap res: 16384x16384px
-Heightmap is 8 bit for technical reason (not recommended for any other planet)
-Heightmap made with gimp and a lot of sweat and tears
-The drone-like particles are spawned in through the weather
-custom ambient sounds (not really, I stole them from me-catalyst)

[h2]You want economy stations around this planet?[/h2]
-Create new world or load world with economy disabled
-Paste in this planet
-Reload world with economy enabled
-Trader station spawn points will then be created around these planets aswell

[h1]Progress update:[/h1]
I have postponed further development of this mod, as there are two problems that I cannot fix and make any further development way too time consuming and ultimately useless. The mod still works fine as is.
It was a cool experiment and it's fun to play around with, but it's pretty pointless to try and push it any further with the games limitations.
