Snow Particle

A soft, cold-white flake surface for falling-snow particle effects — a near-white base colour (0.95, 0.97, 1.0) with a cool blue-grey emissive glow (0.25, 0.3, 0.4) so flakes stay faintly visible in shadow. Transparent, double-sided (cull: none), and drawn in the transparent queue (3000). Built on @builtin::shaders.snow_material.

Inputs

• colors.base_color — the cold-white flake tint.
• colors.emissive (0.25, 0.3, 0.4) — cool self-illumination that keeps flakes readable in dark scenes.
• floats.roughness (0.8) — matte, non-glossy flakes.
• floats.metallic (0.0) — fully dielectric.
