Crystalize is a Geometry Nodes tool for appending customizable crystal formations into Blender environments. The setup generates two distinct types of crystals: crystallites and phenocrysts. Placement is controlled using weight painting, allowing users to assign vertex groups to drive the density of either crystal type independently.

The modifier panel exposes procedural controls for the random seed, radius, diameter range, height range, base height, density multiplier, and the number of geometry sides. The package includes several pre-configured materials that can be assigned separately to the different crystal groups directly from the modifier properties.
