Object interaction

With your scene

Clouds and atmosphere respond to objects in your scene. Real occlusion and shadows, not a flat backdrop.

Continental average OPAC atmosphere preview

Pollution

Based on OPAC OPAC – Optical Properties of Aerosols and Clouds A scientific dataset that measures how real airborne particles (soot, dust, sea salt, water droplets) absorb and scatter sunlight. We feed those measurements into the renderer so the haze you see is physically accurate, not painted in. opac.userweb.mwn.de data

For full control

Every physics parameter unlocked. Dial in scattering, ozone, fog, and more when you need absolute control.

Seamless Transition

At any scale

Atmosphere that works up close with small objects and for scenes outside the planet. One continuous sky at every scale.

Photorealistic

Trusted by your eye

The secret to photorealism isn't the big things. It's the subtle physics your eye learned to trust.

Feels like magic
every time
I use it

Physical Starlight and Atmosphere has been an invaluable tool for me in my personal/professional work and a huge missing link for lighting in Blender. It still feels like magic every time I use it, I can't recommend it highly enough!

Ben Mauro Senior Concept
Artist at 343 Industries

Result was
Photorealistic
renders

Renault built workflow to export thousands of renders for product variations in 360* view. PSA allowed to rapidly test and configure appropriate lighting conditions for this task. Result was consistent and Photorealistic renders for online product builder.

Always gives
my work that
extra edge

Physical Starlight and Atmosphere has been an essential add-on for all of my environmental design projects. It gives me such incredibly flexibility and control over the look and feel of my renders. Lighting is key for any project, and this add-on always gives my work that extra edge.

James Tralie Planetary Science
Producer and Animator at NASA

PSA Gave me
more time

My work life has become super easier since I started using Physical Starlight and Atmosphere, it cut down a lot of technical headache associated with setting up a believable lighting condition and gave me more time to concentrate on the creative part of my design process.

Subin Rajendran Concept Artist

Focusing on the
mood is super
important

As a lighting artist, focusing on the overall mood of an image is super important. Physical Starlight and Atmosphere is based on reality, so I can spend all of my time iterating on the look without worrying about how to achieve it.

Scott Warren Senior Lighting
Artist at Turtle Rock Studios

I love the tool

I love the tool. It has been my go-to since I picked it up a couple of months ago.

Requirements

Atmosphere only
Clouds
Specs

Any GPU (even integrated) that runs Blender 5.2 comfortably, laptops included.

Desktop-class GPU.
RTX 3060 / RX 6600 or better.

What to expect

Smooth. Drag the sun, scrub time, it keeps up. Runs almost anywhere. Sky, sun, moon, planets and stars update in real time even on modest laptops.

Volumetric clouds are the heaviest part of the add-on.

Interactive, not always smooth. Clouds are heavy even for high-end GPUs at higher quality settings. Navigate on Low quality with Temporal Accumulation on: the image refines to full quality the moment the camera rests. Higher presets are for final frames, not for flying around.

↳ We are currently working on performance optimisation to allow smooth workflow for clouds also on slower GPU models.
