Why Atmos?

You need a fast, intuitive, simple solution to give that final key to the realism of your massive outdoor scenes: the atmospheric haze. It's as simple as "Click," "Select, " and "Resize."

You can keep the HDRI background unaffected by the additional atmospheric effect.  You might struggle to bypass that through complex nodes as a VFX artist. But why not simply choose Atmos? (This is what keeps Atmos apart from all other atmospheric solutions.)

You can fine-tune atmospheric haze in real time by resizing the "Atmosphere Object."

You can render faster in certain cases.
