  1. 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 inside my group and delete the other points from the group. Unfortunately my VEX skills are very limited, I seem to be declaring my max function wrong. If someone could help me figure it out that would be great, also an explanation to why my attempt didn't work/ any other solutions towards achieving the same result would be more than welcome. Cheers Example.hipnc and for any questions im trying to make a tool that creates ground slams, as you can see there's distinct circular fractures which im trying to replicate, but also make procedural.
  2. Pyro FX density vs heat

    Hello, Does any one kno why the density field is being used as a binding for the threshold in the shape parameters of the pyro effect simulation once you use the "smokeless flame" preset? Its kind of weird that it takes density into account because density represents the smoke and we are trying to shape just the flames... Thanks, Diogo
  3. I am new to houdini but have been creating effects with x-particles in cinema 4d. I want to port my knowledge to houdini. I would like some help on how to do this effect... Houdini particles is a little bit confusing but I know with a little help on the approach, it can help me a great deal. Thanks (1)_Effervescent_Tablet_-_YouTube.MKV

  5. Hi guys, I’m trying to get POP object and a FEM object to have two-way interaction. The pops are colliding with the FEM, but the FEM object is not being affected by the impact of the POPs. What do people think is the best way to get this to work? Currently I’m playing around using a SOP solver on the finite FEM object to bring in “feedbacks” input. This seems to contain a the particles that hit with fininte element. The pt’s have hit attributes and, “impulse” and a normalised “normal” attribute which I assume is direction. Not sure the best way to apply these feedback points to the finite element. Which attr should I modify and what do we think is the best way to lookup the "feedback" data? Perhaps a point cloud lookup? And suggestions greatly appreciated!
  6. Art directable flip fluids

    Hi, I'm starting to do some flip fluids and I would like to be able to art direct them better, in the example I've attached, the fluids have a lot of art direction, they don't even collide but move like controlled by blendshapes. I can drive the fluids by custom forces and modify their behavior, but I'm having trouble getting an initial shape like that, with the wide leading end and then a flat stream, can anyone sugest a way to get something similar? thank you in advance.

  7. Hello, I have a growing effect on some geometry with the solver, I need the growth to start from one point, which it does, however I need it to look less even and for it to have some random gaps as this effect will become ice with shaders. Any ideas, how I could do this? I have attached the files too Thank you! Corridoor_3_Thickness.obj Corridor_Ice_Spread_003.hipnc

  10. Prep geo for destruction

    Hey guys, I've a question about models. I was reading this article about destruction simulation. The artist, Paweł Rutkowski, mentions something about model prep: Can anyone give advice to what to look for/do when prepping a model for destruction? I'm not talking about naming attributes etc. But normals, etc. Any gotchas I can avoid? Any tutorials out there that would better inform me? Thanks, guys! And a big thanks to all who've answered my previous, probably simple questions. I've learnt tonnes already!! I hope one day I'll be in the position to 'pay it forward' Addy
  11. Brick tunnel

    Hey guys, I'm relatively new to the awesomeness of Houdini. I'm into destruction as an area of the effects field more than I'm into fluids etc. I've a little school/hobby project I'd like to develop, but I'd like some pointers before I begin!! I want to build a brick tunnel which will collapse. (the modelling shouldn't be difficult ). But I'm wondering more about the destruction side. Should I make a basic poly tube, halve it etc. Or should I make something that's procedurally created with bricks? I'm thinking of doing some kind of FEM sim, rather that voronoi, so I wondered how it's modelled would effect how it's simmed? I'm looking to build something like this: I was thinking of applying a similar technique to this discussion: Or is that just wasting time and resources and it's better off to simply texture it? I'd love some ideas before I embark on it!! Thanks Addy
  12. I am trying to do an Ice simulation where the ice appears. I was wondering how I could remove the spikes inside the cylinder and also how I could achieve getting the white parts you see in ice? I tried redoing the simulation but converting it as a volume with vdb but I renders weirdly. Also, I was wondering, if I wanted the ice to start melting (as in a few water droplets), how would I go about, doing this? Thank you! I have attached the files. (File 005 has the vdb attempt but file 006 doesn't.) Ice_Railing_Test_006.hipnc Ice_Railing_Test_005.hipnc
  13. Hi! Houdini beginner here, I am trying to make a basic rain sim of rain interacting with an object and splashing on the ground making puddles. I am having a problem with the particles splashing on the ground, they are acknowledging that the ground is there but 50% of the particles splash against it but the rest go through it and splash just under it, i have tried using different things for the ground like a groundplane and geo but i keep getting the same problem. Any suggestions or help would be amazing! I Have attached the scene file if anyone would be amazing enough to have a quick look? Thank you in advance! Rain_001.hipnc
  14. Granular Sheet - Moving Pin Constraints

    Hey everyone, after unsuccessfully scouring the web and the two big Houdini forums I finally brought myself to asking directly. I'm currently trying to animate a sheet of cloth using a granular sheet since the FEM approach is just excruciatingly slow. I've found three methods for pinning parts of the granular sheet in position (@stuck, @mass = 0, @targetP) but I wasn't able to find a use either of these methods for an animated pin constraint. I'm obviously still not really proficient in Houdini since this problem has me completely stumped. So if any of you lovely people would point me in the right direction, I'd be immensely grateful. Thanks in advance! *edit: After searching some more, I came across this thread: While the file attached to the thread works when I play it, when I try to copy that setup into my scene, it just refuses to work, even though the @targetP gets updated. Obviously, I'm doing something wrong but even comparing the node settings side by side I can't for the life of me figure out what that something is. *edit #2: Okay, I finally figured it out. I didn't realize that the sop solver node is empty by default and you have to create the sop structure to update every frame by yourself. Now that I've figured that out it is perfectly reasonable, I just didn't think of that for quite some time. dia3_dmo_001_010_cgfx_setup_v003_pj_stripped.hip
  15. I'm trying to set up a structure that allows me to import 2D images, PNG/Jpegs into Houdini. Side FX has documentation for this: http://www.sidefx.com/docs/houdini11.0/io/ai Researching this i came across a couple of tutorials, saying that if you want use images you should go for .eps files This is the tutorial i tried to follow, since it covers the Adobe softwares: I'm not sure what's going wrong, whenever i upload my images there doesn't seem to be an error, but I just can't find my imported asset. Any ideas? Cheers, Callan de Keijzer Desktop.zip
  16. Melting plastic approach

    Hey guys! Started some RnD recently on melting plastic with shrinking due to intense heat. Do you guys have any idea how to approach this effect? I have been trying with FEM but denting works but not melting. However I am not sure how flip fluids will shine in this area? Didn't get time to test it out. Any help on this is gonna be amazing. Cheers, b
  17. Hey everyone, Im trying to do a simple disintegration but am running into an issue with a crossed boundary error in the Boolean SOP. On those frames (17, 21) it seems to cause the particles to pop and I am not sure how or really why I am getting the error. I attached a couple pics to show you what is happening as well as my node tree so far. Any help would be much appreciated?
  18. Ocean mesh flickering problem

    Hi, Here is my WIP for a deformed wave. I need some feedback on this. The ocean surface is flickering quite a bit, what's causing this problem and how should i go about fixing? Is this a shading problem or something else entirely? Thanks

  20. Blending 2 waves together

    Hi,I have used the attribute VOP to create 2 separates wave deformers. I would like to blend these 2 together to get the shape that I want. I tried using different attribute nodes but I can't achieve the effect of blending the meshes together. How do I go about doing it?I have attach my nodes network and the image here. You can clearly see that the meshes are separate, I want to combine the mesh. I tried joining the 2 attribute VOPs one after the other but that only increases its amplitude and nothing else, I want the 2 mesh to join at different position so I get a v shape effect like the png image I show here. I thought of perhaps multiplying the 2 wave matrix together by using the attribute wrangle node but i'm not sure how to call out the VOP variables individually when both waves' output is the same (position P). Is there a better way to do this? Any help and advice would be appreciated, Thanks!Eunice
  21. Houdini beginner needs your help

    Hi guys, I'm having a problem I am using two different version that are non-licensed and indie. One of them does not work even though when I copy nodes and expressions exactly the same way. I will attach two different files please help! Thanks Grain_dancer_indie.hiplc Grain_dancer_nc.hipnc
  22. Can't make "Font" function work

    So I've been trying to follow this tutorial: at 13:24 he uses a stamp function and changes it to a 'stamps' (string) then particle fonts change to '0' and he continues with his tutorial. On my project however, 'stamps' doesn't do anything for me. Have I not set up the previous nodes correctly, or did i misuse functions? please help! MatrixScreen.hipnc

  24. Hello, The effect I'm trying to create is a dragon fire effect, However since I've added new translation to the particle emitter and and container the simulation no longer runs correctly. I believe this is to do with the individual DOP networks yet I'm not sure. Any help would be great since I've been stuck on this issue for some time Thank you Dragon_flames11.hipnc
  25. Cloth collision like gum

    Good morning people: I'm a beginner in the 3D world. My main skill is photography and I'm searching a way to integrate some kind of VFX onto my images. Now I'm trying to generate a kind of big sheet of bubble gum colliding with a head. I don't know it the Cloth collider approach is the best or FLIP could be better. I'm stuck in this part, with this setup, I need a more stretchy look but I don't know how to achieve it. Thanks for your time. Best regards, Pelayo. clothCover.hipnc
