Digital Planets

Digital Planets — Procedural Planet & Solar System Shaders for URP & HDRP

Build entire star systems from a single shader library. Digital Planets is a fully procedural planet renderer — no baked textures, no colormaps, no photo editing. Every continent, lava crack, cloud band and solar flare is generated on the GPU in real time and driven entirely by material parameters, so each planet is unique and infinitely tweakable straight from the Inspector.

Designed for space games, sci-fi cinematics and solar-system simulations, the package ships with 8 specialized shaders covering terrestrial worlds, moons, lava planets, gas giants, suns, atmospheres, ring systems and animated solar prominences — everything you need to assemble a believable galaxy.

A distance-based LOD system scales quality automatically from close orbital flybys down to distant background bodies, with tessellation and displacement on desktop/console (LOD 300) and an optimized mobile path (LOD 200). The custom material inspector groups every feature into clean, collapsible sections, and the built-in randomizer generates whole grids of unique planets from configurable range profiles with a single click.

Pure HLSL, fully procedural, zero runtime texture memory for surfaces — drop it into any URP or HDRP project and start populating space.

What's inside

Earth — continents, oceans, biomes, ice caps, shorelines, mountains & craters

Moon — cratered rocky bodies with dual noise terrain

Lava — Voronoi crack networks with HDR molten glow

Gas Giant — animated banding and Fibonacci-distributed storm spots

Sun — granulation, lifecycle sunspots, fresnel rim and HDR emission

Atmosphere — additive glow, 4D animated clouds and rotating hurricane vortices

Rings — banded ring systems with detail texture and shadow casting

Sun Prominence — GPU-instanced flipbook solar flares

Planet Randomizer — one-click generation of unique planet grids

Custom material inspector with collapsible foldouts for every shader
