Node Group
Better Fracture
Get this Node GroupA Geometry Node Group which fractures your mesh in a realistic way. Unlike voronoi fracture, it creates realistic cracks and crevices. All of the important parameters are provided. It also features direction based cutting which is really great for wood-type fractures. Along with it comes a visualizer section where you can visualize the points which are used for cutting references, an exploded view which lets you visualize the pieces by exploding the mesh, and a scale pieces parameter which lets you visualize the pieces by scaling them down.
After you're satisfied with the fracture, you can apply it as modifier, and then go to edit mode > select all (A) > seperate (P) > seperate by loose parts, then Right Mouse Click > Set Origin> Origin to Geometry. Now you can get all the pieces as seperate meshes and use them for your rigid body sims.
