CGMAtter shows how to create procedural crystals in Blender with lots of controls.
CGMatter posts another tutorial, this time showing how to create crystals procedurally in Blender. Sometimes working procedurally in 3D is a necessary thing. Do you need to create a lot of objects randomly? Then why not create a system that does it for you.
In this Blender tutorial, CGMatter shows how you can quickly and easily create procedural crystals. The tutorial shows how to develop controls for attributes like color, shape, size, and even surface properties driven by materials.
