Procedural Snow and Terrain

The visual effect

Soft, art-directable terrain forms create a responsive snowy environment without relying on dense sculpted geometry.

Where this approach can fit

Seasonal landing pages, outdoor and environmental stories, stylized maps, and 3D scenes that need lightweight procedural variation.

What changes in the scene

Vertex displacement along normals driven by gradient noise
Art-directable controls: Noise Scale (frequency) and Max Height (amplitude)
Smooth, stylized results without heavy meshes
Detail scales with mesh density (more vertices - more micro-features)

Rendering approach

Vertex shader displacement, gradient noise, normal-based offset, real-time parameter controls.

Performance notes

Performance is mostly vertex-bound and scales with vertex count. If it gets heavy, lower mesh density or reduce perceived detail by increasing Noise Scale (broader forms) and limiting Max Height.
