The Snow and Ice Geometry Node Pack provides a procedural system for adding winter weather effects to Blender scenes. The pack includes tools for generating dynamic snowfall, accumulating snow on object surfaces, and creating procedural icicles.

The snowfall generator can be attached to any object, turning it into a domain for weather effects. It includes controls for snowfall density, angle, and blizzard conditions, and supports custom snowflake textures. The snow detailing system allows for the adjustment of snow coverage on object surfaces, including displacement settings and resolution control. The pack also generates procedural icicles with options for varying length, size, distribution, and the addition of surface snow layering.
