It's finally time.

This mod allows for the creation of real solar systems with moving planets, gas giants, and stars. There are no limits on scale, speed, hierarchy, or really much of anything else. Supports fully customizable gravity, day cycles, orbit parameters, multiple stars, and much more!

Build as many systems as you want! Order them however you want! The Sun orbits Mars? A dodecanary star system? Gas giant with fifty moons? Why not? Whether you want a scale model of a real system or something more exotic, go right ahead and build it!

The wait is over. It's time to explore a world in motion!

How It Works

Setting Up a World

1. Download empty world to start: Empty World

1 (Alt). Alternately, start with the vanilla "Star System" scenario with your chosen settings and delete all of the existing planets. Make sure "Sun Rotation" option is enabled or sunlight will not rotate based on camera position. Do not start with the vanilla "Empty World" or the light direction for the stars will be stuck at a weird angle (see "Real Stars" mod page for details).

2. Load world and type "/TSE" in chat to open Solar System Editor.

3. Go into spectator camera mode and use Editor to create the solar system(s) that you want.

How To Use Editor

4. Type "/TSE" to close Editor. Save world.

Running on DS

1. Follow "Setting Up a World" steps above and create your world running locally (single-player, not on DS).

2. Save world and exit.

3. Deploy new world to your DS. Make sure to include all contents of the "Storage" folder.

The Editor does not work on DS or MP in any capacity. You must create the world locally first. If you want to use the Editor to modify a world already deployed to DS, you will need to download it and run locally to make those edits.

NOTE: If you have already created the hierarchy that you want for your world and just want to tweak some settings without modifying the overall structure, you can edit the Config.xml files for RealSolarSystems, RealStars, and RealGasGiants on the server directly without redownloading.

The only changes that strictly require the Editor are: -Changes to hierarchy, added/removed planets. -Changes to terrestrial planet size or type.

Preset Worlds

Vanilla Systems The Solar System (Scale Model) Trithorne Cluster Sköll Sector

Compatible Planets

Only modded planets that have had proxies defined for them will have correct visuals when viewed from a distance. Here is a full list of all currently compatible planets:

Get Proxies!

Planet Exporter

This is a tool for creating proxy definitions so that mod planets can be used with RealSolarSystems. Doing so will require you to create your own mod, export textures in specific formats, and use a custom config to create your proxy definitions, so keep that in mind. The Exporter will give you the textures, but creating the mod and proxy definitions is not automated.

Edit Config

How to Edit Config

Console Commands

"/TSE" or "/ToggleSystemEditor" to open the solar system editor. "/DeleteAll" to completely remove all celestial bodies in the world. "/RemoveStrayPlanets" to remove all static planets in the world (i.e. un-managed planets that cannot move) "/AddStrayPlanets" to add all static planets to the RSS system (can be used to convert a world to use RSS) "/SetupRealOrbits" sets all planets to have GravityFalloff of 2, making them compatible with Real Orbits. You may need to save and reload the world for Real Orbits to work after running this.

Controls

Alt+O to toggle planet orbit lines.

Upcoming Features

None currently.

Known Issues (Fix in Progress)

-Small planets may have mountains that poke through their proxy when in ORBIT zone. -Dramatic drops in sim speed after playing for a few minutes (on certain machines) -MES spawns may spawn offset from where they should (can be reduced by reducing spawn range of voxel planets with <VoxelPlanetSpawnRange> values)

Many Thanks!

Special thanks to DraygoKorvan, Digi, enenra, and everyone on the KSH Discord for answering various questions about the engine and saving me from a number of hairy hangups. You guys are awesome!
