Digital Sky Pro

Digital Sky Pro - Complete Atmospheric System

Transform your Unity project with the most comprehensive procedural sky and atmospheric system available!

WebGl Demo (Enable the WebGPU flag in your browser if sky is purple.)

DigitalSky Pro renders the whole sky from one material. Atmosphere, gradient, stars, sun or moon, a sky image and two cloud layers draw in a single skybox pass, and every value is edited in the material inspector. A material is a preset: apply it from the Sky Presets window and the scene's directional light rotates and recolours to match the sun.

Version 2.0 is a full rebuild. The sky is now driven entirely by materials, volumetric fog runs through the URP Volume system, and a new day night cycle blends any list of skies. The code base went from 16,000 to 6,800 lines.

SKY

•   One material per sky, custom inspector, no controller component in the scene
•   30 ready made skies: clear days, sunrises and sunsets, storms, alien worlds, moon nights, aurora
•   Sky Presets window: tile grid with preview icons that are generated automatically for every new sky material
•   8 key colour gradient, collapsible to 2 7 keys
•   Rayleigh and Mie scattering, Mie anisotropy, ozone absorption, ground albedo, scattering floor
•   Background source: procedural sky, or a cubemap or equirectangular panorama with rotation and exposure

SUN, MOON AND STARS

•   The sun moves on an orbit defined by two values, tilt and phase, with a compass in the inspector
•   The scene directional light follows the sun automatically
•   Textured sun or moon disc, texture rotation, Self Multiply mode for flickering rays
•   Star cubemap with atmospheric fade and sun mask

SKY IMAGE (NEW)

•   Place a picture in the sky: a planet, a nebula, a castle in the clouds
•   Azimuth, elevation, size and rotation, Additive or Transparent mode, sun tint
•   Drawn behind the clouds, costs nothing while switched off

CLOUDS

•   Two independent procedural layers, Worley and Simplex FBM with up to 8 octaves
•   Coverage, density, softness, height, speed, lighting, ambient, perspective, edge fade
•   Light and shadow colour per layer

DAY NIGHT CYCLE

•   DigitalSkyCycle plays a list of sky materials and blends every float and colour between them
•   Star, sun and background textures cross fade; sky images fade out and in without morphing
•   The sun always moves forward along its orbit, so a cycle plays as full days
•   Each entry can carry its own fog preset
•   Preview in Edit mode with Run in Editor
•   Own time base: cloud animation stays smooth in sessions that run for hours

VOLUMETRIC HEIGHT FOG

•   URP Volume component: fog settings live in Volume Profiles and blend with global and local volumes
•   Exponential height falloff, base height, bottom cutoff, tint, absorption, Henyey Greenstein anisotropy
•   Main light shadows, point and spot light scattering
•   Tileable 3D noise texture with shape, detail and large scale variation, plus wind drift
•   Downscaled raymarch, bilateral blur, depth aware upsample, Render Graph
•   Classic Unity fog presets for low end targets; the cycle fades between volumetric and Unity fog

LIGHTNING (NEW)

•   LightningStorm component spawns flipbook strikes around the active camera
•   Strikes per minute, distance range, view angle, height, per flipbook overrides
•   Optional directional light flash driven by a curve
