Pattern3D

Overview: These nodes generate true volumetric 3D noise and patterns. Unlike 2D patterns, 3D patterns are evaluated based on world or object position, meaning they flow seamlessly across UV seams and do not require proper UV unwrapping to look correct.

Voronoi3D

Description: Generates a volumetric (3D) Voronoi pattern (cellular noise) that is independent of UV mapping.

Inputs and Settings:
