Houdini - UV Lettering On Geometry

This setup allows you to generate random text and project them onto any input geometry using it's UV.

The technique works by flattening the geometry’s UVs, laying out letters on the UV space, and then mapping them back to the geometry’s world position. I also animate the letters in and out of the UV region to create the illusion of movement across the surface.

It’s a straightforward approach, but the core idea using geometry UVs to project patterns in 3D space is incredibly powerful. Excited to see how others might build on this!

This setup is made using Houdini Indie 20.0.75 and render with Redshift 3.6.04.
