Create: Rocket Atmosphere

English

Features

Ground smoke – when a thruster fires near the ground, a dense cloud spreads along the surface. It fades out gradually once you lift off.

Engine smoke and ascent trails – smoke puffs at the nozzle and a trail that stays behind the rocket as it climbs.

Engine flames – extra sparks and flames at the exhaust, scaled by how hard the engine is working (ignition ramp-up included).

Camera shake – light rumble at ignition, stronger while accelerating, fading smoothly as you move away from the rocket or when engines shut down. More and bigger engines shake more.

Works with the thruster family – Thruster (1x1, 2x2, 3x3), Solid Fuel, Liquid Vector, Vector, Ion and Creative thrusters. Vector thrusters follow their tilt, so smoke and ground clouds follow the exhaust direction. Electric engines (Vector FE, Ion, plasma/ion creative) get a lighter, bluish version of the effects.

Thin-air aware – smoke fades out in low air pressure (no smoke in vacuum).

New in 0.4.0: ignition smoke

When a rocket engine (Raptor 3 and the others) lights up, it now releases rows of small blue-white puffs from the bell, a bright white mist at the nozzle, orange sparks with a few cyan ones, and a much bigger ground cloud for the first few seconds. Toggle with ignitionSmoke in the client config.

New in 0.3.0: rocket engines

Nine engines, all built on Create Propulsion's own thruster system (thrust on the whole contraption, redstone 0–100% power, goggles info). Each needs a fuel and liquid oxygen (LOX) and shuts down automatically if either runs out:

Starship: Raptor 3 (methane/LOX) and Raptor Vacuum (methane/LOX, vacuum-optimised: weak in air, full thrust in space)

Falcon 9: Merlin 1D (RP-1/LOX) · Shuttle/SLS: RS-25 (hydrogen/LOX) · Saturn V: F-1 (RP-1/LOX)

Vulcan/New Glenn: BE-4 (methane/LOX) · Atlas V: RD-180, twin nozzle (RP-1/LOX) · Electron: Rutherford (RP-1/LOX) · Upper stage: RL10 (hydrogen/LOX, vacuum-optimised)

New fluids with buckets: liquid methane, LOX, RP-1 and liquid hydrogen. Each engine has its own 3D model; the exhaust smoke follows the propellant (sooty for RP-1, almost none for hydrogen).

New in 0.2.0

Raptor 3 engine – a two-block-tall engine modelled after the real thing, built on Create Propulsion's own thruster system: thrust applied to the whole contraption, 0–100% power by redstone, goggles info. It burns liquid methane + liquid oxygen (LOX) and shuts down automatically if either runs out. It does not need air, so it keeps firing in space. Includes the two fluids and buckets (creative tab "Create: Rocket Atmosphere").

Space detection – a simple detector (configurable altitude, default Y 3000 = fully black sky in Create: Cosmonautics) and an environmental detector (space dimension, atmosphere flags, air density) that uses Create: Cosmonautics when installed (optional) and Sable air pressure otherwise. Effects adapt: no smoke in vacuum, wider flame plume. /rocketatmosphere space shows the current state.

Install on both client and server now (the engines add blocks and fluids). Effects and the detector run on the client only.

Built for weak hardware (Android friendly)

Quality presets: Low / Medium / High – change them in game with /rocketatmosphere quality low|medium|high.

Global particle budget per tick, distance cut-off and distance-based level of detail.

No per-frame heavy work: effects are computed per game tick, ground checks are spaced out.

Every effect can be toggled or scaled in config/rocketatmosphere-client.toml (max render distance, smoke size, flames, trails, ground smoke, shake strength, electric engines).

Commands

/rocketatmosphere quality low|medium|high

/rocketatmosphere status – shows quality, whether the Create Propulsion hook is active, tracked engines and current shake.

Requirements

Minecraft 1.21.1, NeoForge 21.1.219+

Create Propulsion: Simulated 1.1.5+ (and its own requirements: Create, Sable)

Install on client and server (adds the Raptor 3 block and two fluids). Visual effects run client-side only.

Compatibility notes

Rocket Atmosphere does not modify Create Propulsion files. It reads the thruster state through a small read-only Mixin hook. If a future Create Propulsion version changes that internal method, the effects simply stop showing (no crash); /rocketatmosphere status will report the hook as inactive.

Early release: tuning values (smoke size, density, shake strength) are starting points. Please report issues with your Create Propulsion version, device and quality preset.
