Hello everyone, I recently tested out a simulation I wanted to create on smaller objects and everything seemed to work fine. It's basically a ship on water that gets struck by a missile. The part of the ship where it will get struck is already fractured (rbd). It works fine. So I would like to simulate debris coming from the points of impact and use those same source points for my massive smoke. The only problem is, there is nothing in the debris source. I have brought the packed geometry out of DOP's, unpacked, stuck a trail node and everything appears to be working until the debris source node. This is very confusing because it worked in my simple SIM setup previously but for the life of me, I can't figure out why there are no debris source points. I would appreciate some help on this, and I've attached my scene file to this. Thank you. shipanddestruction.hipnc

Hey There, I am having deep trouble in my Project where i am instancing Fractured Pieces to my Popnet but the Debris pieces are misbehaving after falling. I have created wrangles in Popnet for the (Random Pscale), (Velocity Direction) & (Orientation of Particles), but here comes the issue that when particles fall down then the pieces misbehaving and not stopping it's rotation for the entire simulation. Can anyone tell me what is the problem with that ? What i am doing wrong or what to fix for this ? I am attaching the problem mp4. and some images for better understanding. Thanks in advance for this. WIth Collider view.mp4 Debris Particles misbehaving.mp4

Hey there! Please anyone help me with this. I have made an effect of Ground Fracture, where the fractured pieces are being cracked and from that Debris particles being generated. Here i made debris from the pop network and then instance fractured pieces on my particles. For the collision of debris particles to the fractured ground, i added static object in the dop network, and make the "deforming geometry" on so that Debris particles should collide in behavior to the Ground fracture performing. But when i set these all setup, then the problem occurs of sliding debris. Please can anyone tell me how to not slide the debris. When i normally added Ground plane then the debris is performing fine, but when i add static object as my Ground fracture with "Deforming geometry" on then Debris particles are sliding. What is the reason behind this? I attached some files or examples for your convenience. Any help will be appreciated. Thanks mate! Debris problem.mp4 Debris problem_v2.mp4

Hello all, I am struggling since some months on a problem which I cant solve, I have tried so many things like, have searched YouTube Tutorials but they are for older versions... My goal is, i am trying to do a easy fracture sim like a ball hitting a wall and the wall crumbles. But then I click on the "debris" shelftool and after that I am stuck on the problem, attaching some of the fractured pieces on the particles... I want to learn this on some easy fracture set-ups so that I could apply it later to some complicated set-ups if necessary. I would appreciate some help. and if someone of you had time I would be veeery glad about a Hip file for this problem -
Hey everyone i'm currently i'm watching and learning a Rebelway Intro to Houdini FX Week 06 - Debris Src and i'm stuck middle of training sorry my english is not good i'm facing a issue thought to share it here maybe someone face same issue as me and find a solution i going to make this simple as i can 1- here i have fractured & animated box , the moving pieces of the box going to emit points i used popnet popsolver for that , and everything works fine 2- now when the pieces moving they going to emit points as you see in picture 3- but here go problem , in rebelway training the teacher going to convert the moving object to vdb polygon so he can use it as collision for points and he going to add the vdb collision to system using static object "use deforming geometry" everything works fine for him but soon as i do something like this the points go crazy - i check boundary and normals str but still facing same issue

Hello all, I am quite new with Houdini, just started in the beginning of this month. I enjoy Houdini very much, however, I encounter a problem here and have been here for quite some time. So what I want to do it basically make a scene of a ball crashing a wall and then have debris coming out of the wall as the effect of the crashing and the wall being torn down. Well basically want to get this to the next level. However, I have been looking for a way to do this and found somethings but maybe because I still need to learn more about Houdini, I do not really get how to do this properly. So I thought I can start from a simpler scene first. Firstly I read a post hereand have tried to do it step by step and even try to mimic the scene exactly but I still have no luck. I use Houdini 12 so I grabbed the torus_debris_h12_fix.hip file. I did everything as exactly as how it is in the file, but as from what I check, I see that the "delete" from the particle_location1 does not work properly (If what I see is correct). Although I see this problem, I have no idea how to fix it since I think all is correct I attached my file here. can anyone help me on this? and maybe if you know a tutorial that can be helpful for me to get the hang of this? Thanks in advance houdini_29-09try.hipnc

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 those that haven't seen me post before, I'm an FX Lead at DNEG, and previously worked at ILM / Blue Sky / Tippett. Destruction is my specialty, with some highlights including Pacific Rim 2, Transformers, Jurassic World, and Marvel projects. I've also done presentations for SideFX at FMX/SIGGRAPH/etc, which are available on their Vimeo page. If you have any questions, feel free to ask or drop me a message! https://www.cgmasteracademy.com/courses/25-mastering-destruction-in-houdini https://vimeo.com/keithkamholz/cgma-destruction-

Hey all, How can I add in Houdini 17.5 some debris to an fractured object...so I like to add some smaller debris shards to an object... I have watched on Youtube but I didnt find anything because they have tutorials about this but ONLY for earlier Houdini versions... Help would be very nice...

Hey all, so I have a explosion, but the smoke is like small Squares...that's very strange. What I make wrong...the smoke shouldn't be squares but normal... (I hope everybody understand me, what I try to explain) I hope someone can solve this problem... it would be very nice edit: one file is damaged so try the other Smoke explosion problem.hipnc Smoke explosion problem.hipnc

Hi, I'm Kind of new into this Houdini world and is not an easy world, but I like it, I got this problem: I want to make a fracture with debris, but I want that my debris wit its own geometry, So I searched, and what I understood was this: In the picture the null(out_dust) is the geometry that I want for my debris, and blast 3 is just the popnet but without a floor , when i watch the copy node is working but not correctly, the debris have the geometry that i want but the simulation is wrong, I made an example using poplocation and it works just fine, I don't know if the problem here is beacuse im working with a popsource, any kind of help will be really appreciated. ps: sorry for my english.

Hey all, when I add debris to a fractured object, and then I click on the debris node and after that on "Billowy Smoke". All works fine I can see the smoke emits from the debris and particles...BUT; When I click at Render View and then on "Render", the Smoke doesn't appear. And that happens sometimes. So from e.g 10 times it happens perhaps 3-6 times, that the smoke doesn't appear in the Render view... is this a bug? or what it can be? Because its very annoying, when I fracture an object and then it happens... When I restart Houdini and try it again it works sometimes and sometimes not... I hope you all understand me

Hey, all I have a basic voronoi fracture sim, so then I have add derbis and after that billowy smoke... all works fine I can see the smoke from the debris in the viewport, but I CAN'T see the smoke in my render view? what I make wrong???

hi all so i've been trying to make smoke come off of a pillar as it gets broken but at the moment all im getting is this steamy cloud kind of following the debris parts , and i have no idea how to make them more refined and also to make the smoke more of a thicker trail , any help with this would be greatly appreciated, i am still very much a newbie to houdini.

Hi all i have been trying to make a wall fracture as per a punch and then have smoke and debris come off of it, but at the moment smoke comes off of everything all at once , this is the first year i have touched houdini and didn't start till later in the year so i am still a complete beginner , ive compiled the scene so far from a mish mash of tutorials and how i understand it to work, i have attached my hip file and also the abc of the punch rotomated to a sphere. any help will be appreciated Wall_Fracture41.hipnc PunchRotomation.abc

Hey guys, im kinda new to houdini working on a personal project... ive tried destructions in houdini but im a bit confused as to how to get through this effect i have a similar scene in working on and i need the pretty same impact on the ground i would really be thankful if u guys helped me a bit with this thank you

Hi everyone Wonder in knowing, I am trying to get a kind of loop particles systems, means that when they collide with an object, will recover back their original position and re-simulate creating a loop. Main constraint here is that ptnum must to be constant, cannot die. After this it would allow to set different conditions as reboot when leaves frustrum or after a certain initial age, etc. My only issue is that I arrive at update (in the wrong way for being honest) the velocities to re-do the sim cycle, just that goes in the worng direction, exist a way to make them restart with their initial velocities, attached a HIP file of example. Thanks LoopParticlesTEST.hip

Hey guys, Does anyone knows how can I copy these debris into the Pop Simulation points? (Scene file is attached) copy.fragments.to.particles.v1a.hiplc

Hi, why I have an offset in the debris and the velocity is also missing. Sorry for the missing picture I've tried it with several imagehoster but each time after inserting the URL the input field turns red....??? VDB_crack3_Debris.hip

Im stuck at this point in the particles debris. So my structure collapses to the ground with a typical rbd sim. But when i emit debris particles from them, my particles seems to stop falling after colliding in the top floor of the building and just stays there like a sleeping object. I am using vdb from polygons for my collision geometry which is the geo from the sims. Is there a way to tell the particles to not go still and fall along with the falling building. Thanks alot.

Hello there! I'm new to this forum soo.. nice to meet you guys! Hah anyway, the effect that I want to achieve is like those guns shooting onto Sand, but to make it a digital asset Here are some of my references for the effect. Transformers Fighting Scorponok with sabot rounds Around 1:24. In my file, I used paint to paint the areas where I want the impact to be (From there I emit my particles). I want to make the painted areas (The one that is white has the most velocity, while the black coloured ones has the least velocity). Somehow my POPVOP didn't work. What I want to do: 1. Controlling the force/velocity of the particles (How big the impact of the shoot on the ground can be, the sand shooting upwards) 2. Controlling the distance of how far the particles can go (and then loses its velocity). I know it's too much to ask for, but I hope I get some headstart example file or something, or some advice/notes on how to get the effect. Would be great if you could help out! impact.hipnc

Hi All, I'm relatively new to Houdini and I'm working on a destruction sim of a car hitting a crystal/ice statue. I'm really close to getting a result that I'm happy with but I've hit a brick wall trying to get a fine spray of particles as a secondary effect. Here's what I have done so far: 1. import statue GEO and use a combination of cookie SOPs and Voronoi Fracture to pre-divide the mesh into groups. 2. create an RBD sim using the RBDglueObject node, bring in the low-res car proxy and use it as a collision object. 3. smash car into statue. 4. cache out the RBD as a .bgeo sequence. 5. read in the cache and everything works fine! 6. press the debris shelf tool, this is where things start getting confusing. so I'm getting several odd results, firstly I have to run the sim from frame1, despite having set the debris_sim node start frame value to the correct frame (512). I'm also really confused about the relationship between the constantBirthrate attribute of the POP_replicate node and the constantBirthRate attribute of the POP_source node. My end goal is to use the particles to instance some very simple geo with a copy SOP, however when I do this I find that where I thought there was just one particle, there are actually a load of particles, all occupying the same space, resulting in loads of copies of geo overlapping each other! I haven't uploaded a scene file because my scene is a little heavy but if anybody needs one I'll upload a simplified version with the cache as a .zip Many thanks in advance and any advice or help at all is much appreciated. M.

Hi guys, I'm working on a collapsing simulation and I'm not yet able to emit smoke from collision or from my deleting glue constraint. And I need to have some on the ground. And would it be better to do the debris before or after the smoke. Thanks in advance for your help! I've attached a file of a RBD collapsing. smoke_from_RBD.hipnc
