Vertex Deform Subgraph Library

Vertex Deform Subgraph Library provides clean, reusable building blocks for waves, twists, bulges, springs, and other common effects.

The library is built for fast iteration and easy composition inside Shader Graph.

Included demos

- DemoCannon: BulgePinch thickens the barrel as the cannonball passes; the cannonball flattens with SquashStretch on impact; the wall uses BulgePinch to form a crater at the hit point.

- DemoHeart: two deformation effects layered to create a heart beat.

- DemoSoftJitter: slime body uses SquashStretch + Turbulence; nearby slime blobs are attracted and BulgePinch suggests surface tension during merging.

Requirements

- Shader Graph

Typical usage

- Add a subgraph in the Vertex stage of a Shader Graph.

- Connect PositionOS (and NormalOS if available).

- Drive EffectTime and Strength from properties or scripts.
