In brief
- The add-on includes four procedural cloud layers that can be customized individually.
- Clouds, the atmosphere and lighting update in the viewport as you work.
- Sun and moon positions can be set using date, time and location.
- Advanced mode provides access to physics parameters such as scattering, ozone and fog.
On 4 November 2026, Physical Addons introduced Physical Atmosphere², a sky add-on for Blender. The tool is designed for creating scenes featuring clouds, the atmosphere, planets, the moon and eclipses. Procedural volumetric clouds are rendered in real time, and changes can be previewed in Blender’s viewport. The source does not provide details on the add-on’s price, licensing terms or the full list of supported Blender versions.
How are clouds and the atmosphere configured?
Physical Atmosphere² offers four procedural cloud layers, each of which can be customized. Users can change the clouds’ appearance with a slider, and the clouds update immediately in response to adjustments. The atmosphere and lighting also refresh in the viewport as you work.
The add-on can be used to create daytime, sunset and starry night skies. The developers say that the behavior of light, haze and color is based on atmospheric science. This is a statement from the product team; the source does not include independent image-quality or performance comparisons across different scenes.
Sun, moon and physics parameters
Enter a date, time and location to set the positions of the sun and moon in a scene. This lets you tie the sky’s appearance to the time and place selected for the scene. According to the developers, clouds and the atmosphere respond to objects in the scene and can produce occlusion and shadows. This is different from using the sky merely as a flat image placed behind the scene.
For more detailed control, Advanced mode includes physics parameters such as scattering, ozone and fog. The basic controls are aimed at quick adjustments, while Advanced mode is for users seeking greater control over atmospheric effects. The source provides no measurements on the technical limits of these parameters or their potential impact on performance.
Architectural visualization and Blender workflows
The add-on is not presented specifically as an architectural visualization tool, but Blender users creating exterior scenes may want to explore it for evaluating different sky and lighting conditions as they work. Daytime, sunset and night options can make it possible to try out how a scene might look in different atmospheres. The way clouds interact with objects through occlusion and shadows may also help integrate the sky with the scene.
Before adding it to a production pipeline, check compatibility with your Blender version and performance on your hardware. The source does not specify hardware requirements, licensing model or price. Physical Addons says it continues to support its add-ons with current Blender versions and that its team and community offer help through Discord; however, it does not provide a detailed compatibility list for specific versions.
The announcement also states that the Physical Addons team has 22 years of experience. This is a claim about the development team’s experience, not an independent assessment of the add-on’s performance or suitability for specific workflows.

Physical Atmosphere² may appeal to Blender users who want to treat the sky as an element that interacts with the scene rather than as a static background. Real-time previews could make it easier to test different weather and lighting conditions, but the source gives no performance measurements or hardware requirements, so its impact in heavy scenes remains unclear.
For offices and visualization teams in Turkey, it is important to confirm Blender compatibility, licensing and pricing before making a decision. Trying the add-on in a representative scene before adding it to a production pipeline would be a cautious way to assess its value to the workflow and its performance on your hardware.
Frequently asked questions
What software was Physical Atmosphere² developed for?
