Hello, I'm trying to create a signed distance with curves or a vector file. But I'm having trouble figuring out how to go from one shape to another... Essentially I'm trying to be able to blend from a complicated shape (in the center) to a simple rectangle on the exterior. attached is a simple scene file of what I've attempted so far. Thanks, blendTest01_v001.hiplc

Hey guys, I am a beginner in Houdini working on a project to achieve a glaze dripping effect on pottery. I want the pots to look like the reference image attached. I am attempting to simulate liquid in Houdini to create that outer layer of the glaze dripping. The problem is the fluid is too thick, it is not sticking to the surface of the pot, and its not dripping in that nice tear drop shape that is in the reference image. In the reference images the glaze drips down the body of the pot at the bottom. In houdini the liquid starts to fall towards the floor. I want the liquid to drip down the curve of the pot (until it reaches the bottom of the base). I have to apply this effect to a variety of 3D models (pots). What am I doing wrong? Is this the best way to achieve this type of effect? Any tips would be appreciated, been stuck for a while! I attached the hip and screenshots. FlipFluid_PotGlaze.zip

Hi everyone, I'm currently trying to create an effect of fire burning under a ceiling, looking something like this: http://footage.framepool.com/en/shot/774901137-explosive-flame-fire-disaster-ceiling-fire-blaze As far as I understand the phenomenon there is a layer of gas floating between the air below and the ceiling above. It gets ignited and starts burning at the interface between air and gas. The flames rising up create this kind of nodule structure by constricting the gas into little pockets. This is the theory but I'm completely stumped on how to create the actual effect. I've tried creating little pockets of fuel but the pyro sim simply burns into them, disregarding the fact that there should be no air that makes combustion possible. Does anyone have some experience with this kind of simulation or at least an idea how to tackle it? Any help is appreciated. Thanks in advance Paul

Hello, I have tried to replicate the videos down below. However I got an issue that the sim has a hard time to remain thickness/volume of the upres layer. I could kinda fix it when bringing up the reseeding (surface oversampling) to about 10, but that will change the volume of the sim. Does anyone have any ideas regarding that? https://vimeo.com/108888186 https://vimeo.com/638633520#t=71s

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

Hi Friends! I'm trying to do a floodwater simulation and whitewater came nearly to 1TB, what is the best method to render this as particles or the VDB?(for production use) I have to send this to the lighting artist, sending 1TB caches is tough to deal with for us, looking for help on optimizing

So I have been trying to emerge a temple from under the ocean. but I keep getting this weird collision when it comes from below the water. Looked everywhere if anyone had the same issue, but couldn't find anything. The model is from kitbash and I believe I clean it up and polyfill it so it is watertight. I tried to use another geometry like a super quad from Houdini and that created realistic collisions. Not like in the picture. It seems like it is using the whole bounding box of the vdb of the temple to move the particles. I have collision detection in the solver as Move outside of collision Ocean_emerge_02.hiplc

Im new to houdini and very confused at the moment. I tried creating a smoke portal like effect from particles then using vdb from particles. I created 2 tries. In both i dont know why the some is pretty low res in the viewport. Also i tried changing the velocity scale in the smoke volume sources but they seem to have no effect on the smoke. In the first one the center seems quite static and in the second one no velocity is inherited at all it seems. Any help would be appreciated. portal.hip

Hi guys, I am working on a project where an incense egg is lit from the top and burns down through the object by utilizing the Pyrosourcespread. I have combined this with a modified pyro solver, which i brought in from the Billowy Smoke shelf tool to achieve a denser smoke. In this, two issues occur that i cannot seem to adjust my way out of, with my current knowledge. Firstly, the pyrosourcespread is burning too quickly through the object. Here i am only running with initial fuel which seems to want a value of 7, to infect its nearest neighbours, otherwise no infection happens. This still happens at a way too quick rate. Secondly, i am looking for a way to force the infected area with emitting more, and continous, billowy smoke. At the moment, the negative buoyancy seems to just cover the burned area, where i am looking to have it droop down along the object. The end goal of this project is to have audio influencing the burn in small increments. Apologies for any mistakes. It is just recently that i fell completely in love with the software.

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.

Hi everyone, I try to find a way get a line to stick on my animation mesh with particles. here my setup - I have a body animate - pop-net particules emit on mesh and force to stick on mesh Here my problem I try to convert this particules to line but when i play with trail it's don't stick exactly like my particules on mesh. Like exemple here. Do you have an idea? Thanks you so much

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

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?

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

Hello everyone ! In this introduction, I have created an asset ES voronoi chunk. Also is included the workflow. I thank all the odforce users given that I understand Houdini in this forum. I have not contributed as much as them, but I achieved to learn from the users and I thank you again! I hope that with my work, I can contribute to be part of knowledge sharing of this forum.

Hi Everybody, I would like to get some help/advices to recreate an effect that I find really NICE. So basically, I want to reproduce the effect created on the first shot of this demo reel: http://softimage.tv/demo-2013/ So what I did was to create an animation on a grid geo, with a scale up and scale down + 180 degrees rotation, and I used a copy SOP to copy this animated grid on the points of an inputed geometry (ex: a tube). One way I got the effect working was to use a timeshift based on point number (copy stamp with a value like $PT/500). So, this works alright but I would like to have more control, let say with something that "activates" the animation. A way I could say, when the point color is green, or when this object (metaball) is close enough, now activate and do the animation once. Any ideas are welcome. Also, maybe is there a better approach to recreating this effect? Thanks in advance guys, Christian.

HI guys i have done this realistic bubble burst inside of houdini 18. please comment your thoughts, and do like and share.... Thank you..!

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

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

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

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
