UE4: Procedural Spiral Vertex Shader

Here's a little project I put together that uses basic math equations to offset the vertices of a given surface around a world space location and recalculates the vertex normals based on that offset. The world space location is defined by setting a material collection in a blueprint class, and referencing it in the base shader.

Below is the base material I made to calculate the vertex offset of the spiral and blend it with a world space gradient.
