Quick Interactive Snow Shader

Interactive Snow Shader is a dynamic snow interaction system for Unity that allows characters and other objects to create visible trails and impressions while moving across a snow-covered surface.

The system combines a customizable Snow Shader, Render Texture-based interaction, and VFX Graph to create an immersive snow effect without requiring complex manual trail placement. As the player moves across the snow, the system captures the interaction and uses it to generate a visible snow path on the surface.

The included SnowVFX system adds an additional visual layer to the interaction, creating a natural snow trail that follows the player while they are grounded. The VFX can be customized through exposed properties such as VFX Rate, Life Time, and Size, while advanced VFX Graph controls provide additional control over particle capacity, lifetime variation, and trail color.

The package includes both LowPoly and HighPoly snow plane prefabs, allowing you to choose between better performance and higher-quality snow deformation depending on your project requirements.

Key Features
