  1. Hi. When i search how to make a reaction diffision 2d in Houdini i found this link and hip file: link: https://jbuchert.com/reaction-diffusion-houdini-opencl/ hipfile: https://apolloc.de/index.php/s/O8PTpnmul5ION5J In this hip file i search the F and K parameters for changing pattern and making variations but i cant find. If the reference formula working, than must be have F and K parameters, right? So, how can i change the patter and make variations in this setup. Thanks.

  2. Hi Guys, I searching some references for my project, and i found this. I'm trying echive this effect, but i dont know if it's possible to make it in Houdini, it's maybe about compositing work. You maybe see some films about war where soldier make warpaint with blood or camouflage with some on their face. My goal is make blood and with my animated character make this smudges with fingers on floor. And with this blood make warpaint. lv_0_20210823213128.mp4 soldier-preparing-for-battle-picture-id1050355366 lv_0_20210823151025.mp4

  5. Pyro trails explosion

    Hello, I am trying to recreate the trail explosion at the beginning WITHOUT the rebelway course. I want to challenge myself so please don't say that I should buy the course. I have set the challenge by myself I have figured out how to achive the particle trail simulation and I can do this without any problems. But now I am stuck on the smoke/fire part. I don't know how to attach the smoke correctly to the particles when the particles are moving with fast velocities. Because when I am pressing the pyro fireball shelftool then my particles are showing like smoked points even if I increase the pyro substeps. I can do the particle simulation without problems I hope probably someone could help me here
  6. sliced ribbon cloth effect .

    Hi , is there any guide or starting point to achieve this kind of effect in houdini like this tyflow example ? https://www.instagram.com/p/Bm8nHNfApwE/?utm_source=ig_web_copy_link the confusing part for me not the sim itself , it's how he slice the geo in a continues sliced way ? any input is really appreciated ?
  7. I have a simple problem, but do not know hou to do it. I want to color my sphere with created vector attributes, and let it change frame by frame based on the points of color vector I created as shown in the geometry spreadsheet. It should be easy to do? But I am a newbie, have tried many ways but failed. Thanks a lot!
  8. Hello all! I'd like to preface this with the statement that I'm fairly new to Houdini, come from the art side of things, and am trying baby's first Vex. Please forgive my ignorance. I'm trying to create a melty candle effect and am having some issues getting the candle to build up new wax over old wax without reheating it. This is my first real dive into fluid sim, and I think this is one of those "didn't realize it was a complex sim when I started" scenarios. I've seen a few tutorials on how to do this effect if you are generating the particles, by controlling the temp directly with particle life, but i'm trying to do this effect with the melt object preset, and as far as I know, there is no particle life that can help me here. My question is, how would you approach the issue? I made a very apelike attempt at a popwrangle with a if temp > .9 viscosity is 'insert low value here' else viscosity is 'solid value here' kinda deal. I had no clue what I was doing and it failed miserably. I'll leave it in the side of the DopNet for you to chuckle at should you so choose. It is safely quarantined from the other nodes so it doesn't frighten the children. If I'm approaching this all wrong, please let me know. I'm fairly certain I've got some default settings on this sim that shouldn't be, bad preview settings, etc. . . I'd like to learn the best practices for running these sorts of things. I'm a 3D illustrator/generalist and am trying to add some VFX tricks to my sleeves. I came from Maya over to Houdini a few months back and its still daunting. Really fun though! Thanks for your help!

  10. Sketch and etch style

    Like everyone else, I use a bunch of tools for my work. But I found myself using Houdini more and more for 2d work, including making a sketch or etch style of pictures like these. I did it using sops, and while I imagine there is at least a million ways to do that in Houdini, it was bloody fast, took just a few nodes, and with plentiful variations.
  11. Hi everyone, we meet a problem here. Our group are using Houdini to do the sand interaction effects, but we do the lighting in Maya. How could we do the transfer? For now, we just do the lighting in Houdini to try to match the lighting which we did in Maya. We use the Maya engine to import the sand particles from Houdini, but it occupied a lot of virtual memory. Is there anyone could help us ? We hope to find out how to solve this problem. Thanks a lot!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Looking forward to any suggestions!!!!!!
  12. Hi!!, I'm new at Houdini and I'm trying to get this kind of effect Following this tutorial I managed to make a smoke ring https://qiita.com/r-ngtm/items/c5483f1f4700359e0540 how can I combine it with a dop network to fill it with particles? if there is any other way to do it or if you can give me some advice I thank you sorry for my ignorance Thanks! Thanks!
  13. Hello everyone!! I have seen these organic creations and I have fallen in love <3 How we can do somenthing like this? We need too much VEX code to achieve it? I'm sure that between all of us we can achieve it! Cheers!!!!

  15. Troubles with melting object

    Hi! The newbie is here with a silly question) I'm trying to melt this arm with "melt object" but something goes wrong. Instead of object form filled with dots I only get few in random place.

  18. Hourglass Effect Help

    I'm wondering what would be the best way of approaching an hourglass effect where the sand goes upwards. The hourglass has to be taken out of Houdini and into Maya and is going to be placed into a scene ontop of a table. Any help with how you would tackle this kind of effect.
  19. How Does Vellum Physical Parameters Works ?

    Hi everyone, I'm trying to simulate paper using vellum and I can't get the friction and drag right. I kind of got the result I wanted, though I still don't understand those values. By "those values", I mean static and dynamic friction and normal and tangent drag. I'm a really visual person and there's no example or graph that show's how this works on the Houdini documentation, so I thought that maybe one of you would be able to explain it to me ? Thank you.

  24. Hi Guys, I'm trying to create a constraint network for simulating Car Suspensions, but with no results. I just need a simple "spring effect" between Body and Wheels (please find a video example attached). How I can do it? Any suggestion will be really appreciated. Thank you! I've attached a simple file test I'm working on. Car Example.mp4 Cartest.hip
  25. PointVop Animated Texture

    Hello there! I'm having kind of a hard time to solve what seems to be preety straightforward. I'm using a grid, with a point vop to displace some points on it, but I can't seem to get the displace texture animated. I'm loading it to the texture sequence in texture; if I load a single frame, it works, but with the sequence nothing shows up. Heeeeelp! Thanks in advance.
