  1. Dear odforce, I want to show you this short teaser, which without the treasure of knowledge and tips found within these forums, I would not have been able to create. Please take the minute that it lasts () to watch it, and turn your volume up! A little bit about the project: a former boss at a studio in which I worked needed a quick, raw and eye-catching portfolio teaser that would be independent from client-work. A project that would be created entirely by ourselves, and that would serve as a portfolio-item in the end. I had mentioned to him the idea of having something caught in the moment of shattering, as a photograph, and he found some images that kicked our motivation off. He told me to take this project under my wing, and leave everything up to me.. so my expectations were very high. Based off of the photography, all fracturing-methods felt very CG, and despite how complex my fracturing-setup was, I always ended up seeing these eye-sores which were the typical convex voronoi pieces. Then comes H16 with its new boolean method. The possibility of using custom cutters as surfaces to pre-fracture an object, and simming it with perfectly stable results, changed the game. I started seeing how much customizing I could add to the overall fracture, via VOPS, VEX and everything that makes Houdini what it is (you know what I mean). The rnd of a whole year went to the trash and I put all my hopes into this new method, and after ~220 logged hours, I am really proud to present this fully CG short. You can find some more details to the process in the Vimeo description, and please feel free to ask anything I haven't mentioned. I completely forgot to share this project here, so having just recently updated the video (minor details + new audio) I am doing it now. I truly hope you like it!

  2. hey all! I'm trying to put some noise on the internal faces of a shattered model with voronoi fracture, I promoted the group "inside" from primitive to point to use the mountain sop, but I'm getting noise everywhere...inside and outside...I'm also struggling to subdivide a little more the faces inside keeping a nice topology...does anybody have any idea on it?
  3. Hallo, I have following problem: If I shatter an Object in Houdini, the smaller pieces get an inaccurate guide geometry for the collisions. The Geometry Representation Type is: Convex Hull. Does anyone know a way to make this representation accurate? Would really appreciate it, as the smaller pieces are only spinning around now... Thanks, Zac ShatterGuideGeometryTestproj.hipnc
  4. RDB driven by POP network

    Hello! Firstly, I'm very new to Houdini (coming from Maya), so I apologize if this has been posted before; when looking for a solution I may have just not searched the correct terms. At 49:00 in the below video, Jeff Wagner demonstrates an RBD solver that is 'driven' or on some level involves a POP network. I want to achieve a similar effect. I currently have a shattered object (using another tutorial to create jagged voronoi). Additionally, I'd like to scatter points along the inside point group (from shatter) to create wires, Entagma recently released a tutorial that I can probably use. Getting curves that are affected by gravity would be a perk, but it might be beyond ability trying to make them dynamic constraints to the shattered pieces, etc. If I don't do this however, I might have an issue with them clipping into the geo. Thoughts on how to make them collide-able at least would be appreciated. Would love anything to point me in the right direction. Thanks!
  5. Hi! Just sharing another work of mine, this one took me a lot of time and I like more what this setup can achieve than the result that I got , but at least I finished. Hope you like it!!
  6. shattering windshield

    Hey guys! I'm working on a special effects shot for a short film in which a bowling ball hits a windshield and shatters it. I'm trying to get the ball to actually stick into the glass, or possibly go all the way through. The shot will be from the inside of the car, so I may end up tracking the render to the live windshield footage - or if all else fails I'll just do it practically. Can someone point me in the right direction on how to do this sticky glass windshield kind of thing in Houdini? Thanks!
  7. This is my second installment in a houdini quasi-tutorial series; this is a setup to pre-shatter and sim a deforming character with accurate shatter deformations, custom rigid body activation, bullet packed primitive RBD setup, and post-sim multi-tile UV setup for greater flexibility. I will be following up this tutorial with another on how to create a custom shader setup that includes accurate inside displacements, multi-tile UV layered shader setup for separate shaders/displacement for inside and outside pieces, and how to mix true displacement and bump maps together in one setup Hope some of you find this helpful! Note- As are most things on the forum, this setup is a result of research and techniques compiled from both personal workflows and development and various techniques found here on the forum and elsewhere So thank you to everyone who posts here to share workflows and ideas to make these tutorials possible NJ_character_crumble.hip

  9. Hello world! I'm working on a school project which consists in a gun bullet going through a robot helmet. The modelling and animation has been made in Maya and exported as an alembic. I imported this alembic into Houdini and separated each object of the scene with the Pick option. I added a Scatter node and a Voronoi node on the part of the helmet I want to break. Then I did all the RBD stuff and the destruction works fine except I have a very annoying problem: the shatters of the helmet are too visible. Some screenshots to help you understand: Frame 1 (notice the shatters on the opposite side) Frame 34 (after impact) I'm a noob on Houdini so I might need precise explanations! I've been stuck on this for days and I'm getting desesperate... Thanks in advance for your help!
  10. Hi everyone Just recently finished one of my Houdini test projects, It was mainly for practicing RBD sims, shading, lighting and rendering (Mantra) and also to get a better understanding of outputting passes in Houdini, Please watch the final video here: Hope you like it! Sina
  11. Alright I'm still quite new to Houdini but I'm enjoying its shattering system and its dynamics are much more viable to use over the likes of Maya. My question is whether or not it is possible to bake object shattering and interactions with other objects as set keyframes. Reason for this is so I could possibly transfer it over as an FBX file to Maya. I apologize if this seems a bit obvious of a question. Thanks for any help, Belt
