Create: Orrery
A data-driven planet addon for Create: Northstar Redux, expanding your solar system with new, explorable worlds.
Orrery builds on top of Northstar's rocket and survival mechanics, introducing a flexible, data-driven framework to add custom celestial bodies. Every new world defines its own gravity, atmosphere, temperature, and resources, fully integrating with Northstar's core systems (telescopes, rockets, life support, and more).
✨ Features
- Data-Driven Worlds: A robust
PlanetDataregistry system allowing planets, gravity, skies, and fall-damage scaling to be configured easily. - Telescope Alignment: Seamless integration into Northstar's telescope tracking system, including built-in fixes for sky rendering bugs.
- Curated Surface Generation: Immersive landscapes designed to feel alien. Overworld structures (villages, igloos) are cleaned out, while mod-compat resources (like AE2 meteorites) still generate.
- New Tools & Resources: Custom ore variants and tool-tier progressions mapped to the harsh environments of deep space.
🪐 Explorable Celestial Bodies
🧊 Pluto
The famous Kuiper Belt dwarf planet.
- Environment: Ultra-thin, deep black sky casting sharp, alien shadows.
- Gravity: Roughly 6% of Earth's gravity—even more floaty than Eris.
- Surface: A freezing wasteland composed of nitrogen ice sheets and water-ice mountains.
🌑 Eris
The distant, freezing dwarf planet located in the scattered disc.
- Environment: A pitch-black, star-filled sky with a faint, dim Sun. No atmosphere.
- Gravity: Roughly 8% of Earth's gravity (~0.084g)—expect massive, floating jumps and delayed fall damage.
- Surface: Covered in moon sand and stone, featuring deposits of Copper, Zinc, Tungsten, and Titanium.
