Quick Snow is a Blender add-on for creating dynamic snow over any object by controlling the shader. In one click it can cover an entire scene, and it gives control over every object and material through a range of shader settings. The snow materials are fully compatible with Cycles and Eevee, and ship with a full PBR workflow in 1K, 2K and 4K textures.
Using geometry nodes, Quick Snow builds snow mesh quickly, and its Geotools — GeoSnow Mesh, GeoIcicles and GeoSnow Footprint — add real-time icicles and footprints. The add-on creates dynamic snow material automatically, connecting the principled BSDF, normal map, albedo map, snow shader and snow mask to a snow blend node, and it supports foliage shaders too. Blending options include normal blend, pixel blend and blend softness.
You can animate snow coverage or any shader parameter, add snow displacement through experimental adaptive subdivision, and use auto gravity rotate to keep snow on top of an object during rotation. Masks cover gradient, texture, vertex paint, edge and cavity options. It works with Blender 3.0 and later, now including macOS support.
