  1. Hi, I'm trying to achieve a particular effect which I though would be relatively simple (see attached image.) I have a shot I'm working on where I have a mechanical heart and I want a bullet to go straight through it without losing impact, shattering the heart as it goes. I have pre-fractured the heart geometry with voronoi and used glue to anchor it in place. I then did a simple RBD sim as you normally would when fracturing objects. However, when I used a sphere as a placeholder bullet with initial velocity, it just bounces off the heart. Even when I increase the mass of the 'bullet' it still bounces off. My question is, how would you approach this? I'm completely lost. Cheers!
  2. Simple project to learn Houdini

    I'm new to this place, so apologies if I'm being dumb about anything. The project is to fire a beam at a piece of geometry, and have it fracture at the point of impact, like a simple sci fi gunshot. I have a rough idea of how to do the destruction, but which nodes should I use to cast the ray, and then find the intersection? Also how do you even define a direction or a vector to start off with? Currently I'm using a very long single-span curve, but I'd like to find a way to cast the ray infinitely. Any help is much appreciated. Thanks very much.
