Easy Atmos

EasyAtmos is your all-in-one tool for bringing your Unreal Engine environments alive with dynamic atmospherics. From drifting leaves, bug swarms, smoke, sparks, dust, dense local fog and even crumbling rock formations with the help of your own custom meshes, all of which controlled through a single, artist-friendly blueprint.

No more juggling particle systems or cluttering your content browser with duplicate variations. EasyAtmos gives you full creative control, whether you’re building game or crafting cinematic shot. Every effect can be keyframed, and animated to your liking.

Optimized for both real-time and cinematics use.
