Hi all, Does anyone have a workflow for attaching fractured geometry of an animated alembic, to the animated alembic itself? For example, a moving vehicle that's animated to collide with something and continue moving (the whole sequence of how the vehicle moves is hand animated), so only s...

Hi; I tried to fracture a baked animated character (Alembic), using voronoi fracture SOP. I want to use it in a vellum sim, later. I used "attribute interpolate" SOP to fix scattered points on mesh based on UV. The problem is fractured pieces (and primitive numbers ) are changing over time...

Hi! I seem to be having a small issue with the 'transform pieces' SOP not working as it should. I have a mixamo animation that I have fractured and I use a 'point deform' to get the animation back onto the fractured geo. I want to use the 'transform pieces' SOP to convert my proxy geo to my hi...

Hi all! There's 1 week left to register for my Mastering Destruction 8-week class on CGMA! In supplemental videos and live sessions we'll be focusing on some of the awesome new features in Houdini 18, and exploring anything else you might be interested in, such as vehicle destruction. For...-

I am trying to create a Ground collapse effect on tracked footage(tracked on 3dEqualizer) by projecting the ground texture on to my cube and then fracturing it. However, the texture from the projection is overlapping the effect even after it fractures so only the texture is visible in the scene. I'm...

I'm trying to slice an object during a rigid body simulation. imagine a fruit falling through a grid of laser beam. the object is supposed to be sliced in multiple pieces. i can't pre-crack the geometry as the fragments depend on how the object hits the lasers. like this,

I'm having problems with performing the initial Voronoi fracture with the attached piece of geometry. I'm guessing the problem has to do with either the object being made up of tri's or not having a base face. Any ideas ?

Hello houdini people, Im relatively new to the houdini scene coming from traditional modelling background so go easy on me! I came across a webinar from 2016 with Mike Lyndon in which he talks very briefly about applying a secondary frracture to already fractured pieces around thei...

Hi Everyone I'm currently trying to create circular point groups, inside a voronoi fracture. My outputs are groups currently are primitives but when I conver them to points, i have to many clustered together. I'm thinking of a solution by either getting the max/min two points of each primitive...

Hey guys, I've put this in the 'general' forum, rather than modelling or Fx as I wasn't quite sure which category this goes to.... I have a 'tower' model and I want to fracture it. If I don't turn on 'Create Inside Surface', the fracture occurs as expected, but is 'wafer-thin'. If I...

I may be missing something in the voronoi fracturing SOP, but I can't figure out a way to create clustering without causing fracturing on the geo. For instance. A standard brick will or just group of geo that clusters into groups using the scattering method so I could make the cluster groups bigger...

Hey there, I put together this dynamic fracturing following a tutorial. When I append a rop to export .abc, just the glue constraints splines get transferred, but not the geometry. Maybe the groups are not transferring correctly through the hierarchy? Can't figure out what I am missi... -
Hey all! I'm pretty stuck in a rut trying to think my way through what I want to accomplish with a brick tool I've been working on. Currently I can feed in a box, tube, or an L-shaped box that I've modeled and I can get well stacked bricks around the perimeter. What I'm stuck on is...

hello all, i want to achive the object fracturing with cloth, but when i input the sop solver on the dop simulation to read and animation the pintoanimation, the simulation break and error on frame 6, is there any know why this happen, im follow peter quint tutorial bythe way....

Hello Guys, I am playing around with houdini on an extreme beginner level. Nevertheless I made this setup where I have moving fracture pieces over the surface. My question is. Is it possible to make texture stick to those pieces so not only pieces but also the texture flows and distorts i...

What is the best way to create and controll animation of fracturing on object? I would like to destroy for example house from left to right or any other object. I should play with gradient in VoP or there is better option for this kind of job?

Hello, I'm working on a small project to have a bullet fracture a glass bottle in slow motion. I have come across a few problems while doing so and could use some help.. 1) The time warp is causing some strange scaling issue on the bullet. It continuously scales up and down. 2) During...

Hi I have a question about clustering. The problem is. If I cluster on SOPs then when I come to DOPs I get clustered pieces, but the collision guide shows tetrahedrolized geo over the whole cluster piece. Here is a picture When the geometry is this Is there...

Hello everyone, I am fracturing a geometry and need to delete the pieces bellow a certain size. My problem is that I don't know how to delete based on size. My guess is I need to create a size attribute somehow and then delete based on that. I am sure this should be pretty straight forward but c...

Hi, I'm trying to make an object explosion and I prefractured the object using the voronoi fracture node. Then I use the foreach to calculate the volume of every object and delete it if smaller then n. All works well, but if I enable the option "Add Interior Detail" when the geo passes through t...

Hello everyone, this is my first post here At the moment I have got a fractured geometry, a collision object that interacts with it and an animated bounding box that is activating the fractured pieces in front of the collision object. I want to have a procedural bounding box which is the collision o...

Hello everyone I have got a sphere activating fractured geometry by going through it. I am using a foreach node with a centroid expression inside to add point to each piece which is then activated by the sphere via attribute transfer. Then I am using a point expression on a activevalue in the DOP t...

Is there a way to keep the UVs from getting messed up during fracturing? Screenshots to show you what I mean Before: https://www.dropbox.com/s/mssyfu4wt7ubn29/Screenshot%202014-04-19%2009.54.12.png After https://www.dropbox.com/s/iullbfp6figabxt/Screenshot%202014-04-19%2009.54.53.png...

Hi All Im quite new to Houdini and have a possibly basic problem to tackle! I've set up a fracture system for a barrel I want to simulate exploding. In order to fracture each wooden plank of the barrel separatley (and avoid the voronoi fracture smooshing all the geometry together) I've used... -
Hi all! I've been having a look into using the Open VDB tools for fracturing geometry. While the idea of using volumes seems really promising, giving good control over the fracture pattern and detail, I'm currently running into some issues. I'm not sure whether it's because my approach to it is won...
