  1. Fluids - help!

    Hi team! I have followed a good tutorial on Youtube as I was having issues with keeping fluid in a container, this tutorial also shows how to do bubbles in the water ( Tutorial here ) When the bubbles go through the water there is a loss of fluid and I have been playing around a lot trying to figure out how to prevent the loss, when the collision objects aren't connected there is no loss in the amount of fluid but when I connect the Collison object there is a loss of fluid and I cant figure out how to stop that. I was wondering if anyone else happened to know? Its just bothering me and I wanted to know the answer. Cheers! Hottub.hipnc
  2. Burn vs Fuel

    Hello, I am following a few tutorials on how to make an explosion/fire. Some of them use the attribute burn and others use fuel. Can I please know if there is any difference between the two? Thank you very much.
  3. CurlNoise + Vex Help :(

    Hi there! Houdini noob here ^^ Some days ago I found this image on the internet and I really liked it so I thought about trying to replicate it but maybe animating it hehe to me it seemed like it could be made using curl noise fields so I followed the entagma's vex 101 tutorial and I manage to make this little animation as a test, and I really liked it. I think is pretty close to the image, BUT i have 2 issues with it that i don't really know how to fix or adjust a little, so i was wondering is maybe some of you guys could help me a bit or at least guide me to the right path. https://imgur.com/a/wyg2zMS First: Looping it, is it possible to loop The curlnoise or the curlxnoise? Or is there any other noise function that would produce a similar result but easier to loop Second: Is there any way to soften the curlnoise behavior in these spots? https://imgur.com/a/rLB40Hf My best idea so far i just placing the camera in a place where these intersections aren't in frame haha but would love to know if it's possible at least to make those somewhat less dramatic?

  4. FLIP FLUID Mesh penetrates surface

    Hello Everyone, Particles falling into the object. the particles are penetrating. I've literally tried every single suggestion on every forum and I'm still stuck with this problem. Please look into this. Things I've tried: 1. Substeps increase 2. slip-on collision 3. collision guide offset and divisions. Still, this problem exists. Can anyone help https://i.redd.it/3ziqxtmeo2l51.png

  9. Houdini Bubble burst

    HI guys i have done this realistic bubble burst inside of houdini 18. please comment your thoughts, and do like and share.... Thank you..!
  10. Hello guys ! It has been now 3 years I'm working in the VFX industry. I saw a lot of different FX artist/TD so far and I came to the point that there is many ways of doing a pyro sims as there is artist to make it... From all those different artist, I met people doing amazing simulation from really complicated pyro solver and other with a only a few nodes. There is one specific topic I wanted to get thoughts from you guys was the using of the speed field from the length of the vel field versus the pressure field. People tends to use one or the other as a mask for turbulence, disturbance etc.. in their pyro. Both seems working farely well, but I would like to know more about the prons and cons of those technics ! Looking forward to read your thoughts ! Cheeers
  11. Hello all, I've been trying an effect where a character runs into the water. As soon as the character starts moving and colliding with water little spheres or maybe bubbles start emitting and I don't know why. Below I have attached my hip. file and a screenshot of my exact problem. man_water_run_v11.hip
  12. Generate Wavy Patterns Tutorial

    Hello everyone! https://youtu.be/c4EsWQc7pAE In this tutorial we'll be going over the steps to generate a wavy pattern using simple VEX functions. This is more of a VEX oriented tutorial than my usual videos, but it should be easy to follow along since I will be giving a visual breakdown of each and every line and their effect on the geometry. Thanks to cgwiki's "JoyOfVex" guide that got me motivated to expand on this concept. I recommend you check out his series if you're interested in starting your journey in VEX. http://www.tokeru.com/cgwiki/index.php?title=JoyOfVex
  13. Wetmaps are not visible

    Hi, I am trying to get my model wet by rain. But wetmap is not visible on the object completely. It just shows up on the half body like the only half of the body is getting wet. I have attached my file Thank you rain_nine_v08.hip
  14. 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
  15. Splitting volumes after pyro sim

    Hi, I am creating a scene that is on fire where at one point an explosion happens. I did this by creating a different source for the explosion, giving it more divergence, temperature,.... However since they are merged and both sourced into the same pyro solver (at SOP level, Houdini 18), this is difficult for shading. Since the explosion is way hotter, the temperature scale etc... needs to be different for the explosion. I have thought of just simulating them both seperately but they influence each other so that is not really an option and since it is pretty HQ, it will probably take way longer too. The same basic question has been asked and answered as well: but I have fire and heat and burn and flame fields, so just copying the density fields to different custom fields doesn't work, at least when I tried,... Also the solver is on SOP level in my case because it's easier and that also changes stuff I thin. If you could help me with this I would be eternally grateful! Thanks in advance, Thoran Slock

  18. Hair Guide Transfer Issues

    Hey guys, I'm still fairly new to Houdini and I am trying to make a hair sim for a character on a short film I'm on. I have created my groom on a static mesh of the character and I want to transfer it to the animated mesh. I've imported an alembic cache from Maya, matched topologies with the static mesh, cached that matched mesh out, then brought it back in. I want to transfer the guides to this newly cached mesh, but when I use the guide transfer node, it creates multiple instances of my groom and scatters them around the space. I have also tried the vellum constraint option "attach to geometry" with only the root points selected, hoping the rest of the curves will follow but only the root points moved. Not only that, but they didn't spread across the mesh to their correct position. At this point, I'm not really sure what to do anymore. Any recommendations are welcome. I can attach the file too but I'm not sure if that would be much use since you would need the cache files too.
  19. instance in houdini

    Hi, I'm emitting points from geometry, and points which are below the grid were killed using a pop kill... I'm instancing another geo on it, since the point number is changing my pscale value is also changing for every frame... how to solve this copy to points.hip
  20. normalize in vex and vop

    Hi, sorry about the silly question, I'm a beginner. NORMALIZE in vops, what it is used for, I saw many times in tutorials people using, but, nobody explaining about it... what it differs from the clamp node?
  21. Divergence

    what is the divergence, where we use it? what does it do? is it used only in pyro? an explanation will be appreciated.. thanks in advance!
  22. Hi everyone, I've run into an issue and I'm looking for some help coming up with a work around. We've got a lot of effects that involve smoke trails from characters flying around and we've been using pyro clustering to make the trails. However there is one particular issue I just can't think of a solution to. The default cluster setup transfers the cluster number to a trailed collection of your source points and then finds the lowest source frame in each cluster in order to determine which frame each cluster container should be created on. This works fine normally, however if your trail loops back on itself or comes too close to where it was in world space at another point in the shot then the cluster gets confused as to which container should be used resulting in gaps in your trail. I've been trying to come up with a way to fix this procedurally but keep hitting dead ends. has anyone run into this issue before? Short of trying to convince animators to never have the characters loop back like this does anyone have any ideas on how to circumvent this problem? Thanks in advance, -Brandon
  23. clifford torus effect

  25. Cartoon Waves

    Hey guys, I'm on a working on a film team project that involves 2d cartoon surface water. What I've come up with so far is using a grid and an ocean evaluate to get the base shape and movement and assign two materials using groups and bounding boxes. I want to be able to slow the waves down to slow motion but I'm not really sure how to do that without loosing the size of the waves. 006 has notes and a bunch of previous attempts 007 is the most recent update. 005 is the most recent render. 6 crashed. Any C&C is appreciated SU19_BaseEffects_SurfaceWaterAbove_006.hipnc SU19_BaseEffects_SurfaceWaterAbove_007.hipnc SU19_BaseEffects_SurfaceWaterAbove_005.mp4
