A sci-fi star system generator for Foundry VTT. Generate full star systems with orbiting planets, moons, asteroid belts, linked journals, and explorable world scenes.
One-Click Star System Generation:
Pick a star type, set your planet count, and generate a complete sci-fi system in seconds. The module places the star with a dynamic light source, distributes planets across orbital bands, rolls their properties, adds moons and asteroid belts, and configures the scene automatically.
Planet Scenes and Moon Scenes:
Go beyond the system view. Every generated world can now lead into its own dedicated planet or moon scene, creating a clear sense of scale as you move from star system to world-level exploration.
Site Generator and Site Maps:
Place points of interest directly on planet and moon scenes, generate dedicated journal pages for them, and open linked site maps when you want to zoom in further. This turns the module into a much more practical exploration and campaign-prep tool.
Instant Dungeons Integration:
Site maps can be generated through my other module Instant Dungeons, if you have it installed, letting you go from star system to world to interior location in one connected workflow.
Custom Planet and Moon Images:
Use the included art or replace planets and moons with your own custom images. This was a highly requested addition and makes it much easier to match the exact look of your setting.
Live Orbital Animation:
Planets and moons orbit in real time. Animation runs locally for smooth performance, with periodic syncs from the GM to keep everyone aligned. You can adjust speed, toggle asteroid belt animation, and fine-tune orbital presentation.
Procedural Planet Properties:
Each planet gets rolled stats based on its type and orbital band, including size, gravity, temperature, atmosphere, water coverage, resources, hazard level, and life. Habitable worlds feel distinct from frozen outer-system rocks and hostile extremes.
Journal Integration:
A journal entry is created automatically for the system, with dedicated pages for the star, planets, moons, and sites. Transparent map pins let players click directly into the generated content, and the journal stays in sync as the system evolves.
Star System Editor:
Edit generated systems after the fact instead of treating the first result as final. Swap skyboxes, adjust the star, change planet and moon types, add or remove moons, and keep the journal and linked scenes updated.
Generator Conditioning:
Force a minimum number of habitable worlds or gas giants, or leave it on auto and let the tables decide. Useful when you need a system that fits a specific story or campaign premise.
Visuals and Scope:
Includes multiple skybox themes, five star types with variations, a wide selection of planet types, moons, asteroid belts, linked scenes, and site-level exploration tools. It is completely system-agnostic, whether you are running Starfinder, Stars Without Number, Traveller, Mothership, or your own setting.
