Why we like it

Atmos earns a spot in the superhive library for handling atmospheric haze without a volumetric setup, keeping the sky clear while the effect sits on the ground and letting you adjust it by resizing a single object.

What is Atmos?

Atmos is a Blender addon from CITIGEN for adding real-time atmospheric haze to large outdoor scenes. Unlike a volumetric approach, it lets you keep the sky clear while placing haze on the ground, and it can keep an HDRI background unaffected by the added effect.

The workflow follows a click, select, and resize pattern. You adjust the haze in real time by resizing the Atmosphere Object, and you can save frequently used haze settings as presets to reuse or share with others. In certain cases, rendering can be faster than the volumetric route.

Atmos runs on Blender versions 4.0 through 4.5 and is released under the MIT license. It ships with documentation and includes product updates along with support from CITIGEN. A demo video is available.

Who is Atmos best for?

Atmos is best for blender artists who want to add atmospheric haze to large outdoor scenes while keeping the sky and HDRI background clear.

How much does Atmos cost?

Atmos is completely free to download and use.

Frequently asked questions

Does Atmos work with Blender 4.5?

Atmos supports Blender versions 4.0 through 4.5, so it runs on Blender 4.5 as well as earlier releases in that range. If you are on a version outside that range, check the developer's page for the latest compatibility details before installing. The addon is published under the MIT license, and the listing here includes documentation to help you get started once it's installed.

How does Atmos differ from a volumetric haze approach?

Atmos adds atmospheric haze on the ground while keeping the sky clear, which distinguishes it from a volumetric approach. It can also keep an HDRI background unaffected by the added effect, which might otherwise mean working through complex nodes. In certain cases, rendering with Atmos can be faster than the volumetric route, and you control the haze in real time by resizing the Atmosphere Object.

Is Atmos free to use?

Atmos is listed as free here in the catalog. For current licensing and purchase details, check the developer's page on superhive. The addon is released under the MIT license and includes product updates plus support from CITIGEN. Documentation is provided as well, which helps when setting up your first atmospheric haze in a scene. Atmos runs on Blender versions 4.0 through 4.5 under that license.

How do I adjust the haze in Atmos?

Atmos follows a click, select, and resize workflow. You fine-tune the atmospheric haze in real time by resizing the Atmosphere Object, and you can save frequently used haze settings as presets to reuse or share with others. This keeps the sky clear while the haze sits on the ground, and an HDRI background can stay unaffected by the added effect.
