Learn how to create a fully procedural, proximity-driven crystal growth effect in Blender using Geometry Nodes.

In this beginner-friendly project, you’ll build a system that distributes and orients crystal instances across a surface, reacts dynamically to a moving object, and uses controlled randomness for natural variation.

The tutorial also covers crystal material creation, attribute-driven color variation, lighting, environment setup, and final animation polish.

By the end, you’ll have a flexible setup you can reuse for crystals, sci-fi growth effects, or organic surface details—and a solid grasp of how geometry nodes, materials, and lighting work together.
