Generators are objects that generate new geometry based on parameters and source objects that are placed underneath them. Green icons denote generators in Cinema 4D. If I hold down the Alt key when I create this, it's going to make it a parent automatically, and we need it to be a parent because it is a green object, its icon is green. I'm going to make sure that my object is selected, I'm going to go down here to MoGraph, and choose Voronoi Fracture. So, let's go ahead and create a Voronoi Fracture object. And also, we need that Voronoi Fracture in order to create that procedural growth animation that we're going to use. In fact, let's go ahead and really quickly, add the material onto this, and if we do a quick render, what you'll see is that we get a nice-looking crystal, but we're not getting those fractures in between the material but you'll often see with crystals. Well, one of the great new features in Cinema 4D release 18 is this fully-procedural Voronoi Fracture object, and it does just that. So, now we've got the cylinder here in our scene, and we want to go ahead and break it up and create fractures. So, I'm going to set the Segments to 1 and then we can just sort of dial in the Radius here for how sharp we want it to be, whether we want it to come to a full point or whether we want a little bit of a top cap there. Now I don't want multiple segments because again, I want this to be nice and sharp. And I also want to make the crystal pointed on the end,and for that, I'm going to go into the Caps tab here and adjust the Fillet. We don't want this to be smooth at all, we just want it to be sort of hexagonal, and we're also going to drop the Radius here down to something like 12, so that our crystal is long and skinny. We want it to have sharp edges, so I'm going to drop the Rotation Segments here from 36 down to 6, and that's just how smooth it's going to be. Now, we don't actually want it to be round. And I'm going to go ahead and create a Cylinder object, and this is going to be the basis for our crystal. So, I'm going to go ahead and do this in a new scene, and we'll go ahead and take this one material with us and create a new scene and paste that material in while we've got it. In the scene, crystals grow progressively out of the icy landscape, just before the plant erupts from the ground and for this we're going to use the Voronoi Fracture tool, as well as several MoGraph effectors, including the Push Apart effector, which is new in Cinema 4D release 18. In this tutorial, we'll recreate the crystal growth effect from the Warm Winter scene by Handel Eugene. ![]()
