Objects:
PS_Particles: Procedural object that generates snow particles on input objects.
PS_Mesher: Mesher object that takes particles as input to generate the final snow mesh.
PS_Icicle: Icicle object that takes objects or particles as inputs to create icicles at the bottom of the objects.
PS_Flakes: Animated procedural snow flakes object with a variety of parameters to get the desired results.
PS_FastSnow: An additional procedural object that creates snow mesh based on the topology of input object. Similar to extrusion method.
Modifiers:
[PS][M] FluffySnow: Modifier for mesher to make the snow fluffy.
[PS][M] PolyPrint: A animatable procedural modifier that takes objects as input to create snowprints on snow mesh.
[PS][M] SnowNoise: A procedural noise modifier works based on surface normals unlike default noise modifier. With detailed options to adjust perlin noise levels and dots noise parameters.
[PS][M] SnowSculpt: Brush based sculpting modifier for snowmesh that lets you refine the surface of the snow. Lets you add detail to surface like tiremarks, pathways etc?
[PS][P] ParticleToFlake: A procedural modifier to convert particles to flake meshes.
[PS][P] SnowPaint: Brush based snow paint modifier that creates particles based on the brush strokes. Can be used as input for mesher to make it visible.
