Description

Tornado Shader Breakdown is a January 2022 Cyanilux post on a stylized tornado built with Unity URP Shader Graph. The effect layers alpha-clipped scrolling noise on funnel meshes, adds vertex displacement for wobble, and optionally a Fresnel rim to hide hard silhouettes.

Sections cover Blender funnel UVs (Y-up export), fragment setup for seamless noise scroll and alpha clip, vertex pulsation masked by height, and Shuriken particle trails that swirl into the volume.

For intermediate artists already using Shader Graph and alpha clipping; the graph is Unlit with notes on two-sided rendering when viewed from inside.

Free on cyanilux.com with annotated graph screenshots and per-layer material scaling guidance.

Commonly linked in Unity shader circles as a practical layered-noise and displacement reference.
