🌧️ Ubisoft pulled back the curtain on Anvil using Assassin's Creed Shadows, the first dev video dives into Atmos. Atmos is a real-time weather system: instead of baked presets the engine calculates temperature, humidity and airflow on the fly and decides whether a spot gets rain, wind or clear sky.
Wind drives the core flow sims that shape clouds and precipitation; the particle system respects collisions and carries droplets across geometry for natural results. The same wind data feeds cloth and hair animation, foliage behavior, sound and lighting at once, so weather plays as one coherent system, not a pile of separate VFX. WILD
