Build procedural planets, moons and animated stars in Unity 6.3 URP. Shape worlds live with seeded presets, 16 space skies and High Quality, Mobile and low poly profiles.Unity 6000.3.21f1 with Universal Render Pipeline 17.3.0. URP only; Built-in and HDRP are not supported. The demo uses uGUI 2.0.0. No additional Asset Store purchase is required.Real Planet Generator creates whole planets and animated stars for Unity 6.3 and Universal Render Pipeline 17.3.0. Build space scenes, galaxy maps, system menus and orbital backdrops with editable procedural worlds.REALTIME WORLDSChoose from 52 natural and industrial presets, then change the seed, surface, clouds, atmosphere and lighting through the runtime editor. Geometry and shaders render in real time. Save and load your settings as JSON, or export a PNG preview.PLANETS AND STARSExplore terrestrial, oceanic, lava, ice, gas, desert, thunderstorm, moon and sun types. Combine glowing lava fissures and lakes, rock formations, ice relief, lightning, city light networks and three-dimensional rings. Six star classes include moving solar surfaces, small surface-driven eruptions, secondary particles and lens effects.SPACE ENVIRONMENTSSelect from 16 starry environments with matching surface reflections. Place several independent worlds in a scene with a coherent camera environment.THREE QUALITY PROFILESSwitch between High Quality, Mobile and low poly. The profiles change mesh and effect budgets; low poly provides visibly faceted geometry. Profile names are not device frame-rate guarantees.A reusable runtime API and an interactive uGUI demo are included. Designed for planets viewed from space, not walkable planetary terrain.More from this familyUltimate Earth Planet SystemGeopolitical Earth PlanetPlanet Shader Studio — Mobile & WebGLUnity 6000.3.21f1 (Unity 6.3), Universal Render Pipeline 17.3.0.

Offline-authored flipbook textures animate on realtime particles; the package performs no AI generation at runtime.High Quality / Mobile / low poly budgets; runtime preset JSON save/load; framed RGB PNG preview export; interactive uGUI controls.Space-view rendering, with no walkable terrain or planet collision system. Windows URP validation; no mobile-device FPS or other-pipeline compatibility claim.Generated skies and solar/lightning sprite art are disclosed in Documentation/ThirdPartyNotices.txt. No model weights are included.Scripts and shaders were authored with AI coding assistance. Included art was generated offline using Z-Image Turbo, FLUX.2 [klein] 4B and LTX-2.5: 16 space skies, 11 solar-eruption sprite sheets and 2 lightning sprite sheets. The publisher processed these into Unity cubemaps and padded flipbook arrays, with alpha cleanup, multiple size tiers and runtime integration. The 4x-NMKD-Siax upscaler was used for the 1024-pixel sky-face tier. Detailed provenance is included in Documentation/ThirdPartyNotices.txt. No model weights or AI runtime are included; planets, stars, shaders and particles render in real time.
