Add fog, haze, light shafts and a day-and-night sky to any scene in one click.

AtmosLab fills your Blender scenes with atmosphere: haze that thickens in the valleys, ground fog that rolls with the wind, sunbeams and glowing lamp halos, and a physical sky that runs from noon through sunset to a starry, moonlit night.

Pick one of eight looks and AtmosLab builds the fog, the sky and a sun lamp whose direction, colour and strength match the sky at every hour. Or set a real date, time and place, and the sun, the moon and the stars go exactly where they were on that day, then watch them move in the viewport.

Everything is standard Blender nodes and simple drivers saved in your .blend, so scenes render without the add-on and on render farms. Your own materials are never touched.

Four landscape looks and four cinematic ones, in a thumbnail gallery. Presets change the time of day, the weather and the mood, but never move your sun around the horizon or your fog box, so you can try them one after another.

The scenes below are built with free CC0 models from Poly Haven. The fog, sky and light are AtmosLab, with the fog values adapted to the size of each scene. The lamp-lit lane comes with the add-on as a demo file.

Lamp-Lit Night

Pick a look in the gallery and click Apply Preset. The fog, the sky and the light change together in the viewport, while your fog box and the direction of your sun stay where they are.

Every value stays yours. Open Fog or Sky & Sun and drag any field, and the viewport follows.

Move Elevation or Rotation and the sky, the sun disc and the AtmosLab Sun lamp change together. The lamp's colour and strength were measured from Blender's sky model, so shadows and light shafts always match the sky behind them, from midday to the last red light.

Keyframe the sun for a time-lapse. Below the horizon the sky fades through twilight to night, and the stars come out.

Turn on Use Date and Place, then enter a date, a time, a latitude and a longitude, or press Now for this moment. The sun and the moon rise where they really rise, and the stars turn with the Earth.

Press Play to run the day forward. Live Preview lets the sky move in the viewport, so you can scrub through a sunset and watch the moon and stars come out. In a dense scene the shadows set the speed, so hide heavy collections while you set up the sky.

The moon uses the near side from NASA's CGI Moon Kit, lit by the sun, so it is full when it rises opposite the sunset and a thin crescent next to the sun. You can also place it anywhere by hand. The Moonlight lamp follows the phase and lights the fog.

Stars, a Milky Way band and a faint night glow complete the sky. Turn the star field for star motion.

Put the sun behind something and the beams appear on their own, because the fog really scatters the light. Light Shafts sets how strongly the fog glows when you look toward a light.

A ground layer with its own density, height and softness sits on top of the haze. Its top edge is broken up by noise and drifts with the wind, so it rolls between trees and around lamp posts.

Lamps inside the fog get soft halos on their own; Light Shafts controls how strongly the fog glows when you look toward a light.
