  3. Hi all! I recently made a free public post on my Patreon, a bit of a New Year's gift. In my destruction classes & SideFX conference presentations I've mentioned that I often use geometry grouping to define the clustered sections in my RBD sims. However, it takes a bit of work to create the feedback for-each loops to set that up, so I've finally wrapped it up into a helpful HDA. Demo HIP file included as well. (I also included the HDA in the November 2020 'quick tip' post, but this version fixes a bug in the size-based prioritization, so for patrons that have that version I highly recommend downloading this one instead!) https://www.patreon.com/posts/45769153 https://vimeo.com/496659441 Hope you find this useful, and that you enjoy the new year! :-) ~ Keith

  5. Object collision

    Hi, just wondering if anyone could shine some light on where I am making my mistake within my pipeline? Currently just trying to make my object destroy my said geometry but its pre-breaking before contact? wondering if its because I am not using glue constraints correctly(have tried to use that way) but can't seem to think of what I am doing incorrectly? My next question is offsetting the timer, I have gone into the rdb nodes in the image below and ticked boxes around the creation frame, but it doesn't offset it as it makes it disappear from my scene until the new selected frame. Help is high appreciated as this is contributing to a final grade!!
  6. How to get pyro to effect an rbd

    What is the best way to go about exploding a building with a pyro explosion? Currently I have a setup that has a fractured structure that I add point velocities to and the rbd solver. I want to have a pyro explosion I can use to drive the rbd. How can I do this, none of the tutorials I've seen have pyro. I'm looking for something like this. -
  7. Hi! First post here. After months of lurking and picking up tips from other users topics I need more direct help. I'm quite new to Houdini and I hope you share some ideas. With given FBX meshes, I have to simulate a gate being rammed out from a wall. Chunks of portal around the gate are supposed to be pulled out with it, hit the ground and crumble into bricks while the rest collapses. Gate itself is animated with bones, not physics-driven. After many experiments, I couldn't achieve that two-step fracture (big pieces falling on impact and then crumbling). This is what I've already tried: 1. I've split all wall FBX into bricks using Voronoi fracture fed with array of points (four pieces total: the portal, left, right and top parts of the wall). 2. I've divided the portal into chunks by grouping fractured elements with separate glue constraints. 3. I've created set of constraints for each piece.). 4. I've constrained all parts of the portal to the animated gate. 5. I've imported gate and wall as RDB Packed Objects to a DOP and fed it to bullet solver. 6. I've set up constraints networks for each piece with SOP solvers connected. The idea was that the portal is connected to the gate by glue constraint with infinite strength (-1) and pulled that way out of the wall. After few frames the constraint is severed by deleting lines in SOP solver. Constraints for individual chunks remain until they are broken by impact with ground. Meanwhile the result is that: when portal-gate constraint is removed while the portal is still in the wall, it's being abruptly shot upward. It looks like the animation (which I can't alter) forces meshes to overlap, so they pop when it loses control over them. When the constraint is removed few frames later when the portal doesn't collide with anything, it gains such high acceleration already, that bricks spray all around as if it has been an explosion. I suspect that my pipeline my be noobish, but I couldn't find any resources on similar cases. Unfortunately I can't share screenshots nor files as they are part of a commission. I'll appreciate your help.
  8. Hello, I am a student who was asked to research how to simultate reinforced concrete destruction in houdini. But since I am completly new to houdini, I thought it would be wise to ask some people who have a lot more experience then me how I would go about to solve this issue. I don't need the complete solution or files but just some quidelines/tips how to tackle this problem since I need to find the complete solution myself. (I don't want to steal someones work) My endgoal is to create a simple model of the concrete and steal bars seperate in Max and do a simulation with a bal hitting it at high velocity in houdini. (but for now I want to try some setups on just primitive objects) And the deadline is in a couple of weeks. I am currently looking and following some tutorials about, for example, bending metal and I also saw some examples of mimicking an explosion force using the magnetforce node with a negative value. If there are some veterans who have some advice/guidelines on how to start with this problem, all help is appreciated! Thanks in advance!

  10. Proceedual Concrete Rebar

    Hello, I have question. I couldn't understand how to weld the line inside fracture geometry... It often goes through objects. Is there anyway for to do that..? Or anything tips to reach his flow for me? Thank you Concrete_Rebar.hipnc
  11. Houdini Senior FX TD, destruction!

    Hey Houdini community, Looking for a strong Houdini senior, remote work possible as long as you can somewhat align yourself with the PST timezone, we're located in Vancouver. If you identify yourself with the following characteristics, you may be a good fit for us: – destruction experience (vehicles, buildings, fire, smoke, complex RBD constraint setups) – works confidently & independently – can execute a VFX shot in his/her discipline from start to finish – pragmatic & quick problem solver – 5 or more years of professional experience in VFX – can work with rapid deadlines without overengineering setups Email with cover letter and reel please to: info@stormbornvfx.com We usually do high level hero shots, so that's something that absolutely has to be on your reel, otherwise we can't consider you. Have a look at what we've been doing recently: Cheers, Manu
  12. Howdy! I have a detailed building facade that when I bring the obj into Houdini 18 it is all individual objects, how do i merge it into 1 object so that when i fracture it with Voronoi it doesn't all separate into hundreds of individual pieces but only into the amount of fractures that I define? (Exploded view image attached) Thanks
  13. Destruction I - RBD Simulation

    CG Forge just released a new course that's perfect for those who are new to RBD simulations! Check it out at cgforge.com
  14. Hi guys, most of the tutorials I see on the internet teaches destruction based on assets that are built before being destroyed, giving full control over all the pieces. But how would you approach a situation, where you get an existing wall, maybe a scan of a stone wall, such as the one in my attachment. Let's say I want to keep the stones intact but fracture only the cement binding them? Do I draw poly around all the stones and them boolean fracture? Or maybe I can extract such information from a texture map? I'm pretty new to the amazing Houdini, so I would be very grateful for any tips. Thank you!
  15. How to manually break constraint

    how should i break my glue constraint by velocity enegry_blast.hipnc
  16. Hi ! I am making a project of a bridge destruction and i have a problem that i can not get solved I need to get my rbd to inherit a speed and initial rotation, when they enter the active state. I want to achieve something similar to this https://www.tokeru.com/cgwiki/index.php?title=File:Staggered_fracture.hipnc . but in the sop level and not in the dop. Best regards
  17. Hi all, I'm looking for a solution for an RBD Problem. I'm trying to generate cracks on Object with the shortestpath SOP, which than wil be used to animate the growth of the crack and also will be used to cut out the crack deformation on the surface. In the next step I'm trying to create a first fracture along this cracks. If I use the data I get from the shortest path, my Fracture doesn't work because the Geometry is not Fractured completly trough. If I modify my shortestpath to generate my cutting planes, my pieces don't align with the "modeled" cracks at all. I'm sitting on this problem for more than 2 weeks now made no progress and I'm out of ideas. attached is my setup and a file which shows the idea worj´king but on a Flat wall not a round 3D Object. I already check this Form for solutions but I only could find topics where people asked a similar question but got no answer or topics which are old and outdated. I'm trying to create something simular to the Topic below. If someone could find time to help me it would be very much appriciated. cheers Cracks_with_Fracture_help_02.hipnc dm_wallCrack.hip
  18. Looking for some advice on rendering a smoke/dust sim with a heavy building destruction sim as a holdout using mantra. Without holdouts the smoke takes about an hour or so per frame as expected, but with the holdouts it is taking many hours (up to 6 hour) for some of the heavier frames. I am using packed alembic caches for each of the layers then merging them together and setting as force matte in mantra.
  19. So I am currently working on an earth destruction sequenz were I have 2 layers on top of the earth base which I fractured and is going to collide with an object. I am a little uncertain on how I should go about getting the other two layer to follow the rbd SIM without having to sim everything 3 times. Just a hint or an idea into the right direction would be enough for me. Cheers, Pascal X
  20. Hi Everyone, I have just create a building destruction effect on Houdini . In this tutorial we cover how to use Houdini to creat byuilding destruction with custom deforming. we will learn how to create custom cutting, also learn how to custom clumps for destruction. We also using VEX code to control simulation inside DOP. Please, Feel free to Check in here: https://www.cgcircuit.com/tutorial/building-destruction-part-01 Regards, Nhan Vo
  21. hi i am very new to houdini. currently studying rbd. trying to replicate this effect https://vimeo.com/124015187 I trying to replicate effect of destructing road by a curve, but i dont know how to add randomness to it. i want to apply more up forces so the pieces at first jumps up and then starting fly down by gravity. I have done just the activation of destruction of road by a curve and added a weird jumping but not in a proper way, dont know how to do it like in example. Hope it make sense. Thanks in advance! rbd_add_up_force.hipnc
  22. Destruction Questions

    Hi everyone, I'm trying to do an effect where the default pig head model is raised from the bottom and to look like ice growing and then have a big cube fall and destroy it. I have created two files the first (Ice2) is based on Yongji Chen's lvl 80 article on ice growth. The other is a destruction test following Alessandro Nardini's amazing master class tutorial. I was going to try and see how I could combine them and work the two together and I have had some success but still no luck in combining. In the destruction file, my pig head geometry looks very rocky instead of regular and smooth. I was wondering if anyone had any tips or ways I might be able to accomplish this. I have included both my hip files if anyone wants to take a look. Thank you for your time! destruction_MC_P.hipnc Ice2.hipnc
  23. Destruction Glue

    Hi guys, I tried to attach multiple element in Bullet with different glue (Wall, Wood, Wood to Wall etc... ). Each Constraint works fine. But when i tried to make it works all together , they break. Can you see what's wrong ? Thanks ! Test_Destruction_Chalet_04.hip
  24. 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.

  25. Hello I've been learning houdini the past couple of months (mostly procedural modeling) and I'm moving on to fracturing, destruction and was wondering where I could find a house room (like a kitchen or living room or bathroom) to practice/learn on? Usually those rooms have a lot of different materials to work with and quite familiar. Nothing has to be textured and preferable low poly, it's just for personal/educational usage. Are there any good tutorials/free projects out there to look at as examples that I might not be aware off that arent on the sidefx website? Thank you very much Thank you very much
