Each snowflake is a 3D model based on real-world snow clumps, which get lit, shaded, and rendered realistically. While it can be used in game development, the main focus is on high-quality cinematics, and when combined with Movie Render Queue, EasySnow renders beautiful, falling snow that motion-blurs in a realistic way.
According to the developer, EasySnow also includes a Material Function to easily add and blend accumulated snowfall to all of your models in a level when connected to a Master Material. This world snow Material Function supports Nanite Tessellation/Displacement for realistic results, snow glimmering effects, and full control such as adjusting the amount, the falloff, and the general breakup patterns on the accumulated snow itself.
