Summary

A little shader 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.

The world space location is defined by setting a material collection in a blueprint class, and referencing it in the base shader.

It's also set up with some base parameters for animation speed, spiral depth, radius, and Z direction.

Installation

This download contains the .uassets of the spiral material, the material collection, and the blueprint handle. Just drag the files into your UE4 content folder and they should show up.

It was created in in 4.18, and should work in any version onward.
